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

No more worries about fast engine wear and annoying cold start.

But, the question:

How can you get a high quality and reliable block heater?

Well, that’s exactly what you will learn in today’s guide – from the basic definition, options available, designs, specification, installation process, and many more.

Let’s dive right in…

Chapter 1: What is a Block Heater?

ATV Block Heater

When you ignite the engine of your vehicle, oil flows via the engine block, greasing the moving parts.

In case the temperature plunges below freezing, the oil becomes thick and gets sticky.

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

If sufficient oil is not moving through the engine, it is compelled to work harder.

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

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

They are engine-heating gadgets designed to heat the upan engine, and the applicable fluids before you start it.

Based on the surrounding environment extent of coldness, this device can achieve many vital tasks.

In most cases, the term “block heater” is most used when referring to these engine heating gadgets.

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

The installed freeze plug warms up the coolant that runs through your motor.

It is basic knowledge that the antifreeze does not circulating when you turn off the engine.

However, the heat from the freeze plug transmits all over the cooling system through this fluid and gradually develops a blanket of warmth all over the engine block.

Consequently, this also prevents the temperature of the engine oil from dropping causing a thick, sticky mess.

Installing a block heater in your car makes it operate smoothly during cold weathers and winter.

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

However, most block heaters use electrical plugs.

The cord of the block heater cord at times hangs out of the grille of the car, but you can as well find it inside the hood.

The cable plugs into an exterior extension cord, which you consequently connect into an electrical outlet.

However, it might be difficult to see and locate the block heater cord.

This is because newer vehicles have a covering for the electrical prongs to improve on 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 on certain newer versions or imports.

For that reason, you will have to look for and purchase one.

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

Chapter 2: Types of Block Heater

truck heaters

People install most block heaters directly on the engine block, usually dipped in the coolant fluid.

These type of block heaters are normally more efficient than other models.

 Engine block

However, they may be a bit difficult to install and might need basic auto-mechanic expertise and professional tools.

Dry block heaters or bolt-on models, on the other hand, are easier to install though are significantly less efficient than the former.

Therefore, it is all about you selecting engine heater type that best suits your requirements as well as your budget and expertise.

When making your purchase, make sure you buy the engine block heater from your vehicle dealer’s parts department.

However, in case your vehicle manufacturer does not have one, or it is too costly, the majority of aftermarket auto parts shops will be in a position to assist you to get a universal model.

That is one that fits in your vehicle, normally for a percentage of the dealer’ price.

a) Bolt-On Heaters

Different from typical engine block heaters or the other types mentioned here, a bolt-on heater I external.

Bolt on engine heater

Bolt on engine heater

The heater functions by heating the entire engine by direct contact.

Though effective, a bolt-on heater heats the engine wholly and not the coolant directly.

b) In-Line Coolant Heater

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

This engine heating system is pump-driven, continually moving around the heated coolant to prevent it from thickening due to cold.

In-line heaters are somehow old-school.

They were mainly in wide use before drain plug, and cartridge heaters become popular.

However, they still function as efficiently as before.

And if for some reason, you are not in a position to install an ordinary engine block heater on your vehicle, an in-line heater might be a better alternative for you.

An in-line heater is, basically, a heater that you should install in line 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 and join both ends of the hose to the input and output of the heater.

The coolant will flow through the heater where it will be heated up.

c) Oil Pan Heater

Do not be fooled by the name, the role of an oil pan heater is not to warm up the oil pan only.

This type of block heaters entails a plastic pad which encases a heating element.

You can simply attach the oil pan heater to any metal surface of your vehicle’s engine, and it will warm up everything that is within.

Thought the engine oil pan is the most favorite spot, you can as well install the block heater on the transmission oil pan.

Pre-heating the transmission oil can assist with a hard shift during cold weather.

It will as well minimize the overall wear and tear on the components of your transmission due to cold start.

It is crucial to state that you could utilize more than a single oil pan heater on the same vehicle.

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

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

However, if you have one power cord only, you should connect the two heaters in parallel to make sure they function to their full potential.

Connecting them in series would lead to the two block heaters functioning at only 50% of the overall power.

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

That would be counterproductive.

Be informed that stick-on heater is not as efficient as other more traditional heaters.

Oil require more time to warm up, and transmitting the heat to the oil pan from the heater and eventually to the oil consumes more energy as well.

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

d) Freeze Plug Heaters

A freeze plug heater is a relatively smaller, simpler gadget for protecting your vehicle’s engine from extreme cold.

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

Freeze plug heater

Freeze plug heater

For those who are not aware of what a freeze plug is, have a look at the rear end of your engine and search for round metal cups on the side of every cylinder.

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

They achieve this by popping out if, due to some factors, the coolant fluid freezes up within the coolant passages.

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

Even though freeze plug heaters can be very efficient, you should be aware that their installation can turn out to be extremely difficult.

This is particularly problematic when you are planning to move it from one vehicle to another.

e) Drain Plug Heaters

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

The difference comes in only in the process of installation.

Drain plug heater

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

f) Cartridge Heaters

Cartridge heaters are by a greater extent, the easiest engine block heaters to install.

The only setback is that you can only install a single cartridge heater on your vehicle engine block.

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

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

This way of installation places the heater directly beside one of the channels of the coolant; thereby the coolant will get heated by thermal conduction.

You should opt for this type of engine heating system if your car design factored the possibility of a cartridge heater as an add-on.

The installation of these block heaters take no more than 15 minutes, and they function pretty well as any other engine block heater.

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

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

g) Engine Warming Blanket

Also referred to as power blanket, this type of can hinder your engine from freezing during severe cold.

They are similar to the electric blanket type you might sleep on during cold weather and winter.

Warming blanket

For the engine warming blanket to function, you will have to plug it into a power source.

This aids them in producing sufficient heat capable of preventing the engine from freezing.

Even though thy function well, power blanket can be more of a headache to operate than they are worth.

Basically, engine warming blankets are heavy duty heating blankets.

You only need to glide one beneath the hood after parking your vehicle at night and connect it to the power source to keep the engine of your vehicle warm throughout the night.

Power blankets are the only engine heating system that you do not install permanently on your vehicle.

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

You can as well use engine warming blankets as warming pads that you can spread on the floor.

Of course this when you want to perform some mechanical work inside an unheated garage or your driveway.

You can also complement it with a power pack 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 subsequent vehicles.

Or, if you do not want to worry yourself with any form of installation, then purchasing an engine warming blanket is your best option.

h) Dipstick Heater

You can temporarily place this type of block heater in your dipstick opening to warm up the air and oil within the crankcase to prevent the thickening 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 temperatures plunge below freezing, your engine might have difficulties starting without some aid. Sometimes that help comes from block heaters.

Vehicle covered with snow

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

Here are some of the reasons that should inspire you to consider buying a block heater and the value it adds to your vehicle.

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

Starting your vehicle’s engine when it is freezing strains your engine.

During cold spells, your car’s oil becomes thick leading to a number of unfavorable side effects.

First, the amount of work needed to turn the crank engine by the starter increases when the oil is thicker than normal.

This leads to extended starting times of the vehicle.

Second, thicker oil cannot shoot through all the channels of the engine to lubricate crucial components.

Consequently, when you start the engine, those components rub against one another without any greasing.

These causes wear and tear on the parts, which may result in their damage.

In addition, if the engine of your vehicle is running with cold components that have not warmed and expanded to the appropriate size, they can end up being damaged.

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

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

2) Warms up the cabin of your vehicle faster

Those initial few seconds within a cold car can be just as stressing as they are for your car.

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

The block heater only requires four hours to heat your engine prior to starting it.

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

This enables you to set it to power on 3-4 hour before the time you will be starting your journey.

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

3) Saves Fuel

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

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

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

If your vehicle does not come pre-fitted with an engine block heater, buying such a gadget may appear redundant.

However, if you distribute throughout the lifespan of the automobile, the general cost of a block heater will be a worthy investment in the long run.

4) Benefits for the environment

Since the use of a block heater enables cold-weather starting and quickens cabin warming, it as well reduces the emission of greenhouse gases.

As a matter of fact, tests carried out in a laboratory using a dynamometer showed 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

Parts and components of parking heaters

A block heater is an assembly of many parts and components.

Even the simplest form of block heater has more than one part.

Let me take through these components.

Block heater connection

Block heater connection

i. Combustion-air fan unit

The component is a vital constituent of the block heater because it assists in the supply of air necessary for the combustion process.

A combustion air fan may include the following based on the design of the engine block heater:

  • Engine and impeller
  • Heater label type
  • Control unit having plug-in contacts for electrical connections
  • Vent for combustion-air connection piece and also combustion air pipes

ii. Heat exchanger

The primary purpose of a heat exchanger is to transmit heat to the coolant unit or the engine.

It effectiveness dictates how quick the block heater warms up the engine of your vehicle.

Commonly, heat exchangers have both the interior and exterior section.

Moreover, it may constitute O-ring for suitable sealing.

iii. Petrol or diesel burner

The burner is where the fuel-air mixture and the real combustion takes place.

The fuel flows right into or via preheating compartment having an open shut-off valve.

In this chamber is where the initial preheating happens.

After exiting from fuel needles, its atomization takes place in venture nozzles via which actual air flows.

You should make sure you select a block heater having a suitable burner.

This is because the heater relies on the burner to warm up your engine.

When you choose an engine block heater having an inappropriate burner, it will experience malfunctions and damages which will shorten its service life or lifespan.

iv. Temperature and overheating sensor

Temperature sensors function by detecting the temperature of the coolant inside the heat exchanger of the block heater chiefly as an electrical resistant.

It then relays this signal to the control unit of the engine block heater, the spot here processing starts.

The sensor communicates to the control unit when to initiate and finalize the engine heating process.

 v. A circulating pump

Circulating pump offers feed rates of coolants in heater circuits or vehicles.

It I possible to switch on the circulating pump from the control unit.

To guarantee successful heating, the pump will function throughout the entire operation of the engine block heater.

vi. Metering pump

Metering pump blends entering, transport, and shut-off systems to transfer fuel from the vehicle’s tank to the block heater.

vii. Solenoid valve

Not all engine block heater comes fitted with a solenoid valve.

The valve ensures that the fuel moves into the combustion chamber at specified times during the start-up stages.

After shutting down the block heater, the solenoid valve hinders the fuel from moving into the combustion chamber.

viii. Air bleed screw

The component maintains the engine in form.

The engine block heater cannot function to their potential when the air bleed screw is missing.

For that matter, always ensure it is tight.

 ix. Temperature limiter

The component aids in controlling the heating temperature by making sure the process does not exceed a particular threshold.

It assists in limiting temperature thus keeping it in check.

In simple terms, the temperature limiter acts as a safety measure for a block heater.

x. Flame detector

This is another vital sensor that is instrumental in detecting the flame to avert any chances of fire.

For that reason, it is a crucial safety measure.

xi. Thermostat control

You will come across some engine block heaters having a thermostat control.

The accessory helps in modulating the heating process.

You should note that using the block heater for a long duration may lead to breaking of the coolant hose.

This will be because of the high levels of temperature.

Due to this fact, you will require thermostat control.

xii. Exhaust pipe

Exhaust gases get emitted out of the engine block heater via this component.

xiii. Heating tubes

Through these channels, the fuel and other essential fluids move through the engine.

Disassambled engine heater

Disassembled engine heater

xiv. Electric cord

This cord is very essential in the case of an electric engine heater.

The cords come in varying lengths and sizes.

xv. Coolant circulation system

When purchasing a block heater, it is advisable to always ask for a product manual.

It is from this document that you will have information on all the components and parts of the engine block heater you are considering buying.

Chapter 5: Working Principles of an Engine Block Heater

Block Engine Heaters

Understanding how to operate a block heater is like a rite of passage for any individual in regions where temperatures often 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 small plugs hanging from the grilles of every vehicle you come across on the road.

Have you ever asked yourself what those dangling cords are?

Or precisely how an engine block heater works?

It is a fascinating, yet simple gadget that has presumably saved more engines and helped more people get to work on time 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 temperature employed to maintain the temperature of the engine block.

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

· Thermosiphon Circulation Heaters

A thermosiphon circulation heater functions with passive exchange of heat relying on natural convection, which facilitates the circulation of fluid in the absence of a mechanical pump.

An engine block heater applying this technology has a sluggish coolant flow and functions at a raised supply temperature.

This enables the thermosiphon effect.

Thermosiphon system

Thermosiphon system

Laboratory probing of thermosiphon heaters showed the coolant hitting a boiling temperature.

This leads to hot spots, localized coolant evaporation, and extra maintenance.

In Addition to service and efficiency problems, thermosiphon block heaters often get installed sub-optimally minus appropriate rise to the hoses, which hampers natural flow.

· Forced-Flow Circulation Heaters

Forced-flow circulation heating systems employ a pump to circulate coolant across the heating element and around the engine.

Block heaters using this technology maintain a constant temperature all overdoing away with hot spots in the hoses and engine.

Forced flow circulation heater

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

Electric Engine Heaters

These type of block heaters need electricity as the external source of power.

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

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

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

Electric heater

 Electric heater

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

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

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

Typically, electric engine block heaters lack pumps.

Nonetheless, there exist are those fitted with pumps that assist in the circulation 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.

Engine heater

 Engine heater – Photo courtesy: Over Drive Heavy Duty

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

Installing heater


There exist different kinds of block heaters, and the specific type you select will rely on the make and model of your car as well as your mechanical capability.

The simplest type of engine block heater being one that substitutes 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 located at the bottom of the engine block.

Block heater

 Block heater

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

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

Other types of block heaters, such as in-line coolant heaters, are comparatively easy to install if you are conversant with a vehicle engine.

However, you would rather get a professional when installing traditional freeze plug block heaters.

In case you resolve to do the block heater installation by yourself, you should remember one crucial element.

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

In any event, the cord comes into contact with moving parts such as belts or pulleys, it 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 engine block heater types we have highlighted above.

Step One: Jack up the Vehicle

Working on a cold motor vehicle will prevent you from experiencing burns.

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

Select the alternative that you are comfortable working with.

Block heaters have different wattages.

Therefore, choose one that satisfy 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 commencing this procedure, it is essential to confirm with your user’s manual for guidelines specific to your block heater.

Detach the clips holding the cover of the radiator and bolts holding the mounting bracket of the radiator.

Glide a pan below the engine of the vehicle and pull out the designated 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, however 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 require you to fasten them 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 dependent on the temperatures you are working.

In case you stay in a region where it becomes cold to ice up your antifreeze and fracture your block.

Then it will be wise you plug your engine block heater anytime you have your vehicle parked for any duration of time.

You should always plug in a block heater overnight if the temperature is speculated to drop below levels your antifreeze cannot sustain.

Nonetheless, if you happen to be in an area that provides power outlets for block heaters, plugging in will lead to easier starts.

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

In scenarios where it does not get extremely cold capable of cracking your engine block, you can always cut cost on 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, hot air from the vent much faster, and reduced wear and tear on the engine.

Chapter 7: Applications of Block Heaters

· Rated Voltage

Typically, block heaters come in different voltage rating.

The most common rated voltage fall range from 110V – 120V/220V – 240V.

· Rated Power Consumption (W)

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

They are different depending on the kind and size of the engine block heater you desire to buy.

The rated power may range from 500W, 1000W, and 1200W or even higher.

· Working Temperature

Because of the inbuilt temperature sensors, the block heater will automatically halt operation when the temperature hits 65°C.

The engine heater will resume operation when the temperature falls below 45°C.

· Weight and dimension

They differ based on the heater’s design.

Nonetheless, most block heaters have their weight ranging from 1Kg to 2Kg.

For this reason, make sure that the engine heater you are planning to purchase adheres to the RoHS, FCC, TUV, and CE requirements.

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 enables it to fire up without troubles due to cold start when you power the engine on.

VVKB Engine heater with inbuilt pump

VVKB Engine Heater with In-built Pump

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.
