Block Heater: The Ultimate Guide(2021 Version)

Block heater ensures rapid heating, fuel efficiency, and fast ignition.

It reduces the stress of fast engine wear and annoying cold start.

It has many qualities. Yet, some questions remain. How can you get a high-quality and reliable block heater?

Well, that’s exactly what you will learn in this guide. We are starting from the basic definition to the options available. We also include designs, specs, setup process, and many others too.

Let’s just dive right in.

Chapter 1: What is a Block Heater?

Engine Heater Titan-P1

Let’s start from the basics. What happens when you ignite the engine of your vehicle? The oil flows via the engine block, greasing the moving parts, right?

Often, the temperature may fall below freezing. As a result, the oil becomes thick and sticky.

So, this makes it difficult for the oil to flow through the engine.

If enough oil is not moving through the engine, it forces itself to work harder.

As a result, your engine parts can get worn out.

Engine Assembly and Working Principle Video

This is where the block engine comes into work.

A block heater is a small electric heater that works within the engine of your vehicle.

They are a type of engine-heating gadget. It works to heat up an engine, and process the applicable fluids before you start it.

This device can handle many vital tasks of your engine. The tasks depend on the surrounding climate.

Often, the term “block heater” comes up when referring to these engine heating gadgets.

Most designs entail a “freeze plug” fitted in place of the expansion plug of your engine.

The freeze plug ignites the coolant that runs in your motor.

We all know that the antifreeze does not work when you turn off the engine.

Yet, the heat from the freeze plug transmits all over the cooling system. It goes through this fluid and forms a blanket of warmth all over the engine block.

So, this freeze plug prevents the heat from cut-offs. It causes a thick, sticky mess of heat around the engine oil that stays.

After you install a block heater in your car, it will start to operate. This runs smoothly especially during cold weather and winter.

Some block heaters operate directly off your vehicle’s diesel or fuel supply.

But, most block heaters use electrical plugs.

Sometimes, the cord of the block heater hangs out of the grille of the car. Not to worry, you can as well find it inside the hood.

The cable plugs into an exterior extension cord. Hence, you connect this plug into an electrical outlet.

But, it may be hard to see and locate the block heater cord.

This happens often with newer vehicles. These vehicles have a covering for the electrical prongs. This covering improves the safety of the cord.

Still, there may be other reasons you cannot locate the plug.

Automobile manufacturers do not pre-install block heaters anymore. As we say this, we point towards certain newer versions or imports. Older versions may still have it, but it’s uncertain.

For that reason, you need to find out and buy the right plug.

In case you lack the installation skills, it is best to hire a professional. Let them do the block heater installation on your behalf.

Chapter 2: Types of Block Heater

truck heaters

People often set their block heaters right on the engine block. That’s why they usually stay dipped in the coolant fluid.

These types are more active than other models.

Installation Diagram of Block Heater

Installation Diagram of Block Heater

Yet, they are a bit hard to install. You need to have basic mechanic expertise and professional tools.

Then again, dry block heaters or bolt-on models are easier to install. Even though they are less efficient.

Thus, it is all about selecting the engine heater type that suits your needs. You also need to take the budget and expertise in the count.

It is ideal to buy an engine block heater from your vehicle’s dealer. So if you are buying one, make sure you contact them.

In case your vehicle company does not have one, don’t worry. Sometimes it is costly too. In such a situation, most aftermarket auto parts shops will be able to assist you to get a universal model.

If you really can’t find it, you can log in: www.RVheater.com to buy.

They will find you the one that fits in your vehicle. They do it for a percentage of the dealer’s price.

Bolt-On Heaters

Let’s talk about one of the most different from the regular engine block heater. It is none other than the external bolt-on heater.

Bolt on engine heater

Bolt on Block heater

Here, the block heater heats the entire engine by direct contact.

This bolt-on heater heats the engine in an effective manner.

Just like other block heaters, it also heats the engine by heating the coolant.

In-Line Coolant Heater

The design of an in-line coolant heater enables it to maintain the coolant. It keeps the coolant above a specific heat to keep it in a fluid state.

This type of engine is pump-driven and always moving around the heated coolant. This way it prevents heat fog on cold.

In line cool and heater

In-line heaters are kind of vintage and indie style.

They were in wide use before. But then drain plugs, and cartridge heaters come up and become more popular.

Yet, they are still as efficient as before.

In case you are not in a position to install an ordinary engine block heater on your vehicle, it’s fine. An in-line heater may be a better alternative for you then.

An in-line heater is a heater that you should install in line. you do it with the engine’s coolant circulatory system.

In simple terms, it is a heater you are at liberty to install anywhere you wish. Commonly, you would fit it near the thermostat or at the output of the radiator.

You simply slit a segment of any coolant hose on your car. Then you can join both ends of the hose to the input and output of the heater.

The coolant will flow through the heater where it will heat up.

Oil Pan Heater

Do not let the name fool you. The role of an oil pan heater is not limited to oil pan only.

This type of block heater entails a plastic pad. So it encases a heating element.

You can simply attach the oil pan heater to any metal surface of your vehicle’s engine. Then, it will heat everything that is inside.

How to Install Oil Pan Heater

Now, many people takes engine oil pan as their most favorite spot. But you can as well install the block heater on the transmission oil pan.

Pre-heating the gearbox oil helps. They does it with a hard shift during cold weather

It will as well cut the overall wear and tear on the components. This affects your transmission due to cold start.

Know that you can use more than a single oil pan heater on the same vehicle.

For instance, you could use one for the engine oil. Then use the other for the transmission oil.

Even so, always use two different power cords for such a connection.

But, if you have one power cord only, you should connect the two heaters in parallel. That way you can make sure they serve to their full potential.

Connecting them in series leads to less performance. Then the two block heaters would serve at only 50% of the overall power.

This means that you will have to plug them frequently. This is to meet the same outcome as in parallel connection.

That would be counterproductive.

You need to know that a stick on heater is not as efficient as other old heaters.

Oil needs more time to warm up. Same happens when transmitting the heat to the oil pan from the heater. As a result, the oil consumes more energy as well.

On the other hand, these heaters are affordable, easy to install. You can have several of them in one vehicle.

Freeze Plug Heaters

A freeze plug heater is a relatively smaller and simpler gadget. It is to protect your vehicle’s engine from extreme cold.

They are block heaters that you install directly on the engine block of your vehicle. They works as a substitute to one of the freeze plugs

Freeze plug heater

Freeze plug heater

If you are not aware of what a freeze plug is, have a look at the rear end of your engine. Search for round metal cups on the side of every cylinder.

These plugs’ role is to prevent your vehicle’s engine from crashing.

They achieve this by popping out. The coolant fluid freezes up within the coolant flows.

Freeze plug heater is one of the most usable types of engine block heaters.

Even though freeze plug heaters can be very efficient, you should be aware. The setup process can turn out to be difficult.

This is particularly tricky when you plan to move it from one vehicle to another.

Drain Plug Heaters

The working principle of a drain plug heater is nice. It is almost similar to that of a freeze plug heater.

The difference comes in only in the process of installation.

Drain plug heater

Drain plug heater

During their installation, drain plug heaters replace the drain plug of the engine block. It does it instead of freeze plug as is the case with freeze plug block heaters.

Cartridge Heaters

Hands down, the Cartridge heaters are the easiest engine block heaters to install.

There is only one setback though. It is that you can install only one cartridge heater on your vehicle engine block.

On certain car models, there exists a special metal casing. It stay close to the coolant chamber.

This is normally on the engine head’s side. There you can always glide a cartridge heater and fasten it to a bracket.

This way of setup places the heater right beside one of the channels of the coolant. So the coolant will receive heat by thermal conduction.

You may have a design factor where the cartridge heater works as an add-on. If you do, you should not opt for this type of engine heating system.

The installation of these block heaters takes no more than 15 minutes. Then they works pretty well like any others

Still, cartridge heaters tend to cost more than other block heaters.

But, it is worth the investment. Imagine, you never have to experience leakage of freeze plug coolant with this type of block heater.

Engine Warming Blanket

These types are like power blankets. They can hinder your engine from freezing.

They are like the electric blanket type you might love to sleep on cold nights.

Warming blanket

What do you do to make the engine warming blanket to function? You have to plug it into a power source.

This aids them in producing enough heat. This way it is capable of preventing the engine from freezing.

Even though they function well, power blankets can be more of a headache to operate. This is less in comparison to worth.

Basically, engine warming coats are heavy duty heating blankets.

You only need to glide one beneath the hood after parking your vehicle at night. Then connect it to the power source. This way it will keep the engine of your vehicle warm all night.

There is only one type of engine heater that you can’t install permanently. It is none other than the Power Blankets.

This property gives you the flexibility to use it on more than one vehicle. It also lets you decide on the time you would like to use it or not.

You can also use engine warming coats as warming pads. You can use these to spread on the floor.

It is obvious that you want to perform some mechanical work inside an empty garage.

You can also complement it with a power pack. This is to give heat when winter camping by putting it under a sleeping bag or a tent.

If you need an engine heating system that you can keep and re-fit on your following vehicles.

Or, if setup bothers you, we have a solution for that too. Purchasing an engine warming blanket is your best option then.

Dipstick Heater

You can temporarily place this type of block heater in your dipstick opening. This will warm up the air and oil within the crankcase. As a result, it is to prevent the cloud of the fluid during cold weather.

Warm oil offers better lubrication for a durable, smoothly-running engine.

Chapter 3: Benefits of a Block Heater

When the climate falls below freezing, your engine might face difficulties. It then needs some aid to start. Sometimes that help comes from block heaters.

Heating Effect Diagram of Block Heater

Heating Effect Diagram of Block Heater

These engine heating systems are a perfect investment. They boosts the lifespan of your car and to make sure it is set to operate at all times.

There are many reasons to desire and consider buying a block heater. Below are some of those reasons and values that add on.

Minimizes stress to your engine, starter motor, battery among other engine components

If you start your vehicle’s engine when it is freezing, it strains your engine.

In a cold atmosphere, your car’s oil becomes thick. This leads to some negative side effects.

First, as the oil gets thickers, the amount of work needed to turn the crank engine by the starter increases.

Working Principle of Block Heater

This leads to extended starting times of the vehicle.

Second, thicker oil cannot shoot through all the channels of the engine. They usually do it to lubricate crucial parts.

So, when you start the engine, those components rub against one another. But they don’t grease

These cause wear and tear on the parts. Later on they may result in damage.

Also, there are other ways your engine may receive damage. if the engine of your vehicle is running with cold components it happens too. Especially if they are not warmed and expanded to the appropriate size.

Starting becomes difficult, and this wears out your engine parts.

Moreover, it harms not only the engine but also your starter motor and battery.

Warms up the cabin of your vehicle faster

The initial few seconds in a cold car can be just as stressing as for your car.

When heating your engine coolant fluid using a block heater, your vehicle’s cabin can suck in heat. This can happen almost right away after starting it in the morning.

The block heater needs one hour to heat the engine at the start.

The newer engine block heaters make it possible to install timers on them.

This lets you set the power of one-two hours before the time you will start your journey.

The timer can assist you to save up to about $25 on your utility bill.

Saves Fuel

In most cases, you will save up to 15% of fuel during the initial 20 Km of driving. This is of course if you install an engine block heater in your vehicle.

And if you are wondering, hybrid vehicles enjoy the 15% fuel save as well. Even though that extra 15% in fuel-efficiency is insignificant. This is because hybrids usually combust less fuel.

The bigger your vehicle’s engine, the greater the savings. It is that simple!

Unless your vehicle comes with a pre-fitted heater, it’s expensive for you.

The general cost of a block heater will be a worthy investment too. This is if you distribute the lifespan of the automobile in the long run.

Benefits for the environment

The use of a block heater enables cold-weather starting. It quickens cabin warming as well as reducing the emission of greenhouse gases.

As a fact, tests are carried out in a laboratory using a dynamometer. The results show that a plugged-in motor vehicle releases:

  • One-sixth the amount of carbon monoxide
  • One-fifteenth the quantity of hydrocarbons
  • One-quarter as much nitrogen it would produce if you did not fit it with a block heater

Chapter 4: Main Components of Block Heater

Next, let’s look at the main accessories of the block heater:

Heater Accessories Diagram

Heater Accessories Diagram

Electric heating element

The electric heating element is the main part of the heater.

After the electric heating element receives energy, they generate heat.

It transfers to the coolant inside the heater later on.

Electric Heating Tube for Engine Heater Titan-P1

Electric Heating Tube for Engine Heater Titan-P1

After that, the coolant will move to the engine parts to complete the heating.

The electric heating element is usually an electric heater tube. There are also block heaters that use PTC heating elements.

Electric Heating Tube for Engine Heater Titan-P5

Electric Heating Tube for Engine Heater Titan-P5

Inside the electric heating, the tube is an iron-chromium wire. It stays connected to two power terminals.

Wonder where they are? They stay between the iron-chromium wire and the wall of the electric heating tube.

It fills up with magnesium oxide powder. Inside the heater tube, there is almost no air present. This will extend the service life of the iron-chromium wire.

Electric Heating Tube for Engine Heater Titan-P3

Electric Heating Tube for Engine Heater Titan-P3 and P4

The typical service life of electric heaters can reach 8000 hours.

The power of electric heating tubes goes in a wide range. They start from 500W to 1000W, 1500W, 2000W, 2500W, and many more. They conform and can heat various engine sizes.

We offer three different types of electric heaters.

One is the ordinary electric heater, which is steep in the coolant.

Electric Heating Tube for Engine Heater Titan-B1

Electric Heating Tube for Engine Heater Titan-B1

The other type is a die-cast electric heater tube in an aluminum case. This protects the heater tube. This can extend the life of the electric heating tube.

There is another kind of PTC heating piece, which has fast heating up and high thermal efficiency.

Water pump

The heater can rely on gravity flow to get the purpose of heating.  It uses the water pump to assist the flow. This way, the heater works much better.

Block heater water pump coil

Block heater water pump coil

The block heater is set next to the engine. So, this figures out that the shape of the heater cannot be too large. And the water pump as an auxiliary device, its size should be relatively small. Thus, the power of the water pump will not be very high.

Usually, the water pump inside the engine block heater is one of a kind. It consists of a miniature magnetic pump that has the same structure as the water pump. It cleans the water in the aquarium.

The structure of the pump of the block heater is:

In a motor frame made of silicon steel sheet, there are two coils. Then in the position of the head of the silicon steel sheet, there is a magnet of ferrite. This magnet is set inside the stator of the pump by a stainless steel shaft. At the head of the stainless steel shaft, there is an impeller installed.

Block heater water pump rotor

Block heater water pump rotor

When the coil gets energy, a magnetic field builds inside the silicon steel sheet. At the position of the head of the silicon steel sheet, the magnetic field cuts the ferrite. This makes the ferrite move. As a result, it drives the impeller to rotate.

The coil will generate a high temperature when working for a long time. This requires the coil’s enameled wire to be heat resistant. The usual enameled wire for the cylinder heater needs a certain amount of heat. It is somewhere near 180 degrees Celsius (356 degrees Fahrenheit).

Temperature controller

Many block heaters only have heating tubes and wires. They are also not paired with a heat controller due to the power being too low.

But, a block heater without a thermostat is an obvious safety hazard. It can cause antifreeze to boil or other safety incidents due to high heat.

Block Heater temperature controller

Block Heater Temperature Controller

Such a heater with a thermostat can take the heat up to 65 degrees Celsius (149 degrees Fahrenheit). This gets rid of the potential for antifreeze boiling and fires due to high heat.

The temperature controller is a temperature protection device with a ceramic body structure. Inside the ceramic body, there is a bimetal.

At the head of the bimetal, there is a silver contact. It can move, and this silver contact moves with the bimetal.

On the base of the ceramic body, there is another stationary silver contact.

At room warmth, the stationary silver contacts on the base of the ceramic body. Also, the movable silver contact on the bimetal is touching each other.

When the ceramic body detects that the heat of the heater is slowly increasing, the bimetal will bend. Also, when the heat reaches 65 degrees Celsius (149 degrees Fahrenheit), the silver contact is on the ceramic base.

The silver contact on the bimetal can then completely cut off the power.

When the heat drops to 45 degrees Celsius, the two silver contacts turn the power back on.

We have two heat controllers for the heater. They attach to the zero and fire wires of the power supply. Two temperature controllers can make the heater safer.

Block heater sealing ring

The block heater with a built-in water pump consists of different types of fittings. There will be gaps between these fittings.

Block heater sealing ring

Block heater sealing ring

We need to seal these gaps. We use silicone rubber seals as sealing material.

Silicone rubber seals are resistant to high temperatures and abrasion. Even if the heater is not set up, you can use these seals again.

Block heater connection cable and plug

There are two options for the connection cable of the block heater.

One type of linkage is that the cable coming from the cylinder heater comes with a plug.

Block heater connection cable

Block Heater Connection Cable

It connects to the power supply and the heater is able to work that way.

The advantage of this connection is that it is easy to install.

Also, it only requires placing the plug inside the cabin or next to the cab.

But, it can be troublesome to power up the heater.

Connect the cable to the block heater

Connect The Cable to The Block Heater

You need to open the engine compartment cover or open the driver’s door.

Another way to connect the heater is to have a connection port on the heater.

Connection cable connection method

Connection Cable Connection Method

This is compatible with our matching connection cables.

We provide two connection cables. One of them is with armor protection.

It is inside the engine slot to prevent electrical safety from the high heat.

European standard plug

European Standard Plug

It prevents those who can cause damage to the cable.

The other cable connects the bumper plug to the power supply.

It is a cable that makes it easier for you to operate the heater.

American standard plug

American Standard Plug

One side of the cable with armor connects to the heater and the other side stays on the bumper.

When you need a heater, you only need to connect the external power supply to the connector of the bumper.

Then connect the power supply, and the heater will be able to work.

Block heaters are mostly called for in many cold regions of the world. So you will need to choose the right plug style for your country’s standards.

We prepare for you.

  • European standard plugs, suitable for Europe, Korea, Russia, and Mongolia, etc.
  • American standard plugs, suitable for the United States, Canada and Japan etc.
  • Australian standard plugs, suitable for Australia and New Zealand, as well as Argentina and China

Block heater shell

The ordinary block heater has no housing, it mounts directly on the cylinder.

Block heaters with built-in water pumps usually have a die-cast aluminum ingot housing.

The block heater fills with antifreeze inside. That’s why this puts strict demands on the heater housing. As a result, it needs the heater housing to be leak-proof.

So, the heater housing is usually die-cast on a very high-pressure machine.

This machine is in need to completely exclude the air holes and sand holes. These holes and sand holes exist inside the aluminum coat.

After the shell die-casting, it is also necessary to do the anti-leakage treatment. Do it to the shell to ensure that the shell will not leak.

The advantage of this connection is that it may take a few extra minutes to install. But trust me, it’s worth the time. It will save you a lot of time later on in the process.

Chapter 5: Working Principles of an Engine Block Heater

Heating Effect Diagram of Block Heater

Heating Effect Diagram of Block Heater

Understanding how to operate a block heater is like a rite of passage for everyone.

The climate often changes. They even fall below the freezing point and where winters are very harsh.

You realize you are living in a cold region of the world when you observe in detail. Small plugs hang from the grilles in such climates. It happens to almost every vehicle on the road in winter.

Ever wonder what those dangling cords are?

Or how does an engine block heater work?

It is a fascinating, yet simple gadget that has presumably saved more engines. It also helps more people get to work on time. This is faster than any other motor vehicle add-on that is winter-specific.

Engine Heater Technology

Thermosiphon circulation and Forced-flow circulation heaters increase the engine coolant heat. Their work is to maintain the heat of the engine block.

The difference between these two is in the technique of circulating the engine coolant.

· Thermosiphon Circulation Heaters

A thermosiphon circulation is a heater. It serves with the passive change of heat. It relies on natural convection. Also, it helps the flow of fluid in the absence of a mechanical pump.

When an engine block heater applies this tool, it gets some issues. It has a slow coolant flow. It also functions as a raised supply temperature.

This enables the thermosiphon effect.

Thermosiphon system

Thermosiphon system

A lab test finds out that, thermosiphon heaters a sign. It shows the coolant hitting a boiling hot surface.

This leads to hot spots and localized coolant evaporation. It also takes extra care.

Also to service and efficiency problems, thermosiphon block heaters often get installed sub-optimally. It cuts off proper rise to the hoses. This all stops the natural flow.

· Forced-Flow Circulation Heaters

Forced flow spread heating systems use a pump. This flow coolant across the heating part and the engine.

Block heaters using this technology can keep a constant temperature. This way they don’t overdo any spot. Hot spots in the hoses and engine need such care.

Truck Block Heater

Forced flow circulation heater

This block heater type also hinders low-coolant alarms. Along with coolant boiling, and coolant concentration problems.

Electric Engine Heaters

These types of block heaters need current as the outer source of power.

Let’s have a quick look at how it serves.

The engine block heater has a heating element in it. It is within the engine block.

You can connect the heating part to an external power supply using its external cord.

Engine Heater Titan-P1

 Electric heater

Electric block heaters can swap one of the core plugs of the vehicle.

In most cases, the system gets fitted by diving the heating element in the engine’s coolant.

It keeps the vehicle’s engine warm by heating the coolant.

Typically, electric engine block heaters lack pumps.

Nonetheless, there exist those fitted with pumps. This assists in the flow of the warm coolant all over the vehicle engine.

Diesel or Gasoline Engine Block Heater

With these engine block heaters, there is no need for an exterior power supply to warm up the engine.

They are some of the most convenient block heaters since you can heat up your engine anywhere and anytime.

As the name suggests, these engine block heater types operate on diesel or gasoline.

You can operate the heaters on either gasoline fuel or the diesel of your vehicle.

In this type of block heater, either the diesel or gasoline combusts to generate the heat needed to warm the engine block.

Diesel Water Heater

Diesel Engine Block Heater

The block heaters have a pump, which transmits gasoline or diesel to the combustion chamber.

Air-fuel mixture takes place in the combustion chamber.

The mixture ignites and combusts to generate heat as soon as it gets to a certain threshold.

Transfer of the heat generated to the engine then takes place via heat exchanger.

Typically, these block heaters employ thermosiphonprinciple to run.

In this concept, engine heater system preheats the engine coolant fluid by convection.

The heated coolant will consequently move upwards through the hoses to the engine of the vehicle.

On this account, the rising air dislodges the cold coolant that flows down into the block heater system.

The cycle goes on and on till your vehicle’s engine attains a suitable temperature.

For optimal performance and reliability, you should determine:

  • Size of the block heater to purchase based on the surface area of your vehicle’s engine
  • Quantity of coolant that should be heated
  • Temperature differential
  • Environmental conditions

If undersized for the use, these standardstipulations may lead to low-temperature alarm signals and an engine that fails to start.

In summary, engine block heaters mainly function under forced-flow circulation and thermosiphon circulation concepts.

Nevertheless, some block heaters entail advanced working technology to boost efficiency.

Chapter 6: How to Install Block Heater

There exist different kinds of block heaters. The type you select will rely on the make and model of your car. You should also take your mechanical powers into the count too.

The basic type of engine block heater is the one that swaps the oil dipstick.

A modestly more complicated block heater type mesh into the upper radiator hose.

You can install it within minutes using a screwdriver.

The most efficient types of block heaters substitute a drain plug. It is located at the bottom of the engine block.

Installation Diagram of Block Heater

Installation Diagram of Block Heater

Engine warming blanket and dipstick block heaters are easy to install. You can also transfer them from one vehicle to another.

Actually, installing a dipstick heater is much easier than checking your car’s oil.

There are also other types of block heaters in this line. The in-line coolant heaters are examples of those. They are easy to install if you are familiar with a vehicle engine.

But, you would rather get a professional to set up in the traditional way.

What if you want to do it by yourself? You certainly can. It’s just there are some elements that you need to keep in mind. You need to resolve them to do the set up by yourself.

Each engine block heater comes with an electrical cord. You need to route within the engine compartment safely.

In any event, the cord comes into contact with moving parts. Such as the belts or pulleys. They can get damaged.

If such a scenario occurs, your block heater will not function, or even short circuit the next time you power it on.

Let’s look at the general guidelines for installing an engine block heater type above.

Step One: Jack up the Vehicle

Working on a cold motor vehicle will stop you from having burns.

But operating on a warm engine? It enables you to easily detach the drain plugs. Even in case the metal used to make them is different from the engine block.

Truck Engine Heater

Truck Engine Heater

Select the alternative that you are comfortable working with.

Block heaters have different wattages.

So, choose one that meets your needs and is in harmony with your car.

Jack up the forepart of the vehicle and detach the plastic casing of the engine.

Step Two: Drain Engine

Before you do this procedure, there are some essentials to do. You need to confirm with your user’s manual for guidelines specific to your block heater.

You have to detach the clips holding the cover. It stays with the radiator and bolts holding the mounting bracket.

Glide a pan below the engine of the vehicle and pull out the marked drain plug.

This is normally located at the back end of the engine block. Take out the cap of the radiator to fasten drainage.

Step Three: Plugin Heater

Pre-fit the joint between the power cord and the heating rod if you have to perform it blind later.
Put the male tip of the cord into the engine compartment.
Oil the rod or hole using grease up to, but not beyond the metal clip.
Lodge the rod inside the hole, and in case the trapped air is exerting resistance, use more grease to displace it.
You should place the metal clip so that it faces the back of the vehicle.
It will produce an audible snap if the block heater glides into position.
Some types may need you to fasten them. Do it by using a wrench to a particular torque.

Step Four: Route Power Cord

Fix the cord onto the rod. Route the wire harness via the engine compartment and out through the front grille.

Make sure you adhere to the stipulated instructions or improvise.

Ensure you do not move any hoses or parts.

Once you have placed the cord in the right position, tighten it using wire ties.

You should not leave any looseness behind the first tie.

Also, you need to ensure the cable does not come into contact with the engine manifold.

You now own a car that will be more fuel-efficient!

Using a Block Heater

The best way to run a block heater is up to the heat you are working.

In some cases, you may live in a region where it becomes cold to freeze up. This way you antifreeze and fracture your block.

Then it is wise to plug your engine block heater anytime you park your vehicle for some time.

You should always plug in a block heater overnight. Do it if the heat is to drop below levels of your user level.

Still, if you happen to be in an area that provides power outlets for block heaters, plug in and make it easy.

Besides, it will reduce wear and tear on your vehicle’s engine. This happens even if you are not parking overnight.

On the other hand, the scenarios can be different. It can be normal where it does not get extremely cold, capable of cracking your engine block. Then you can always cut costs of electricity by employing a timer.

You can set the timer to power on the block heater 3-4 hours before you get into the car every morning.

Doing so will help you void the wastage of electricity for overnight heating.

But you will still enjoy the advantages of an easier and quicker start. The hot air from the vent is much faster, and reduced wear and tear on the engine.

Chapter 7: Applications of Block Heaters

Block heaters often find use in areas with cold winters. Such as Canada, northern United States, Scandinavia, and Russia.

In these regions, It is standard to have block heaters in vehicles.

In extreme cold weather, you will find electrical outlets a lot. Most of them are in private or public parking lots. You can select the one multi-story car park.

Certain parking lots switch the power supply for about 20 minutes. It also switches off for about 20 minutes. This way it reduces the costs of electricity.

Chapter 8: Block Heater Technical Specifications

Sample technical specifications of car engine heater

If you’re planning to buy a black heater, you need to confirm the following technical specifications:

Block Heater Titan-P1

Block Heater Titan-P1

· Source of Heat

Depending on the type of block heater, it may use electricity or fuel.

The fuel may include gasoline or diesel.

· Rated Voltage

Typically, block heaters come in different voltage rating.

The most common rated voltage fall range from 110V – 120V/220V – 240V; 12V/24V

· Rated Power Consumption (W)

Just as rated voltage, the rated power of block heaters is not always similar.

Chapter 9: How to Troubleshoot Block Heater

If your engine block heater breaks down during cold weather, you will need to perform some speedy repair to have your car up and running properly.

As I have already stated, a block heater helps in keeping your vehicle’s engine warm during cold days.

This mechanism is practical with majority other diesel engines, and on other vehicle models that incline to have congealing problems with the oil or other fluids within the motor.

Locating the source of the complication on these devices would entail inspecting the electrical outlet to your garage or home to make sure it is not a bad wired connection or blown circuit.

Step 1: Inspect the Power Cable

The initial step in repairing your block heater is checking the power cord to make sure it is working correctly.

To perform this, connect the power cable to a working outlet, and confirm whether the coil and the heater unit are becoming warm.

If the heater does not warm up, then you might be having a broken power cable.

Driving away with the cable still plugged in, or it getting pinched or entangled in something are some of the causes of this problem.

This is always the first area to inspect and ensure to observe and confirm that the power cord connection to the heating unit is done correctly.

Poor connection to the block heater could as well lead to a complication with transmitting the right voltage.

Step 2: Replace the Heating Unit

The next frequent problem relating to engine block heaters would probably be the heating unit, which others sometimes refer to as the heater coil unit.

This is the electrical attachment of the block heater, and you can easily replace it by unfastening a few screws.

Simply remove the old unit, and then connect your cable to the new one before reinstalling it.

As you take out the wiring and related connections on the power unit, make sure you label the wires to avoid confusion when you will be reinstalling them.

When working with the electrical parts and components on your vehicle, ensure to detach the negative terminal of your battery to prevent electrical shock.

Step 3: Replace the Heater Block

If during the repair of your engine block heater, you do not realize any electrical problems, and the device is still not working correctly, there are higher chances that it is the block heater leading to the complications.

You can easily remove this part from the engine, and the technique of carrying out this is ordinary, and you can execute it without much hassle.

You will have to drain all the oil and excess fluids from the engine of the vehicle before detaching the block heater to prevent a serious mess of things during the exercise.

Remember to label all the electrical connections during the process of disconnecting the old unit.

Keeping track of the connections help you avoid electrical cross wiring.

The replacement parts varying in prices.

They usually come with guidelines on how to correctly assemble them, since some of the process can differ based on the make and model of your vehicle.

Step 4: Check Thermostat

A faulty thermostat can lead to too little or too much cooling.

When it is thrust open, the engine will require quite some time to warm up since the coolant will flow at all times.

You can take out the thermostat and probe it in a basin of almost boiling water.

It ought to open slightly before the water hits the boiling point, then shut as the water cools.

You should replace the thermostat if it does not move.

The only method to fix a faulty temperature sensor or thermostat is to substitute it.

Other Fixes for Block Heater

If the coolant level is low, or there exist an airlock (after substituting any faulty parts), you ought to fill the system appropriately.

To carry out this, tune the block heater controls in the vehicle to maximum heat.

Take out the radiator lid (or remote mounted coolant pressure lid, at times on the overflow tank) and top up to the right level.

Now turn on the engine without returning the lid and idle for some minutes.

Check for the level of the coolant to fall as the thermostat opens.

With the engine still running, maintain the coolant topped up to the maximum level.

Compress the top radiator hose to promote the pumping of air around the system (ensuring that you avoid contact with any moving parts, specifically the radiator fan).

You should force out all the air between the water pump and the engine heater.

Once the coolant is full and warm, return the lid and test drive.

Preventive Maintenance for Block Heater

At times, you may consider the following preventive measures for your block heater:

Step 1

Regularly examine hoses and replace if need be.

Step 2

Once every year:

  1. Take out electrical box cover and examine the electrical connections.
  2. Take out the heating element from the block heater. Make sure you do not destroy the O-rings. Cleanse and flush inside of the heating element casing and wipe the surface of the element of any coolant deposits.
  3. Shake the heating element holding tank as you observe and listen to the movement of the valve. If you fail to see free movement of the valve, substitute the valve assembly and retaining ring.
