To make a guided choice, read through this article that covers the finest brands of engine block heaters. After going through the user reviews, take a decision that you won’t regret later on.
In case you don’t want to read through the reviews, here’s our top 3 choices for the best engine block heater:
What is an Engine Block Heater And Benefits Of Using It?
The engine is the most important part of any automobile. It is through the engine that oil is transmitted. Oil makes the other parts of the vehicle move, and thus we are able to drive.
In very cold climates, the engine hits a low temperature. The oil that flows through it is naturally viscous and cannot flow smoothly if not warm enough. Colder climates don’t make it easy for the oil to flow through if the engine is cold.
This is where we need an engine block heater. It’s embedded within the engine of your car and heats it up.
Basically a small heater, it preps your engine before you turn on the ignition. The freeze plug in the heater warms up the coolant so that the flow through the engine is smooth.
There are several benefits to using this product. Read on to know more.
Prevents Engine Wear-Out
Since the car block heater warms up the engine, the latter is in the right state before starting to work. Thus, there won’t be any premature wear and tear. It doesn’t have to work extra hard as it’s already warmed up.
An engine block heater like the freeze plug prevents the engine from getting cold. It surrounds the cooling system and the engine in warmth. Thus, you won’t get any mess from sticky and thick engine oil.
If you have a block heater for car, you’ll get mental peace. That’s because your car will operate without any hitch. This is especially a much-needed feature for vehicles operating in extreme cold conditions.
With an engine block heater, it’s easier to start your car after a very cold night. Without it, you’ll not only find it hard to start your car, but you will also cause damage to the engine.
An engine block heater will save fuel for you. For the first 20 kilometers, your vehicle will save at least 15% gas. These savings are even higher if you own a bigger vehicle like a Jeep, that houses a bigger engine.
Since an engine block heater prevents the engine of your vehicle to start before it reaches the optimum temperature, there is less emission of gases that are harmful to the environment.

How To Choose The Best Engine Block Heater
With a host of engine block heaters available, making a buying decision is a tough choice. However, you need to consider several factors before making the final purchase of an engine block heater. Read on to know more.
Temporary Or Permanent
Engine block heaters can be either temporary or permanent. Depending on whether you need one for a short vacation up north or you live permanently there, it will be a deciding factor for your purchase decision.
If you’re in the market for temporary heating solutions for your car engine, pick a dipstick heater or an engine-warming blanket, or an oil pan heater.
However, if you live in extremely cold regions, other types of engine heaters should give you more long-term solutions. You could go for the most efficient type of heater for your car – in-line coolant heater or freeze plug heater.
Not all weather conditions demand the use of a car block heater. It’s only the extreme cold to very cold climates where you need a heater for your vehicle. Due to this type of climate, the coolant and oil in your car freeze, causing damage to the engine.
It’s only when the temperature goes down to 5 degrees Celsius then you ought to run the engine warmer.
The bigger the engine of your vehicle, the bigger the power or Wattage of your engine block heater is needed. For example, the tractors and trucks used on a farm have a big engine. For these types, you need a truck block heater with at least 300 wattage power.
Ease Of Installation
Some engine block heaters are easier to install, while others need professional help. Before you choose one, first decide if you want to install it or get the pros to do it. Depending on your decision, select the right engine block heater for you.
The stick-on types of heaters like the dipstick heater, oil pan heater or the engine-warming blankets are the easiest to install. Others require more expertise as these need to be in electrical harmony with the engine system.
If you own more than one vehicle that runs regularly, then you need to choose a heater for your engine that can be used on multiple cars. You can opt for an engine-warming blanket.
This type of engine warmer installation is temporary. Therefore, you can move this from one to another vehicle easily.
You can also get an oil pan heater to warm up your fleet of cars. Although they are not the most efficient, they still provide the warmth that your vehicle engines need in cold weather.
Types Of Block Heaters
Engine block heaters are available in a few types. But they all use the basic mechanism of heating to keep the engine and fluids warm. Let’s take a look at these types.
1. Dipstick Heater
A dipstick heater for an automobile engine is placed in the part where the oil dipstick is usually found. This is a temporary heater, easy to install, and directly warms up the oil and air. Thus, the cold weather cannot make the fluids thick. Hence, the warm oil keeps the engine running smoother and for a long time.
2. Bolt-On Heater
This type of an engine block heater is latched on the outside of the engine. It heats up the engine directly, which in turn, heats up the coolant. It’s totally effective but the installation part is difficult.
3. Engine-Warming Blankets
This is a larger size heater for your car, especially suitable for cold weather. It will make sure your engine doesn’t freeze.
This type of engine heater needs a power source to be plugged into. You need to put it under the hood and turn the switch on. The heat is spread uniformly and keeps the car warm throughout the night.
This is a temporary installation and gives you the flexibility to use it on other vehicles as well. This requires no such installation and is, therefore, easy to use. Moreover, it warms the entire car, much like an aftermarket car heater.
4. In-Line Coolant Heater
This type of heater for vehicles is installed in line with the engine’s coolant circulatory system. More specifically, any part of the coolant hose is selected and a slit made. The two parts are then connected to the heater’s input and output.
When the coolant flows through the system, it will be warmed up. You can also put it near the thermostat or at the radiator’s output.
The installation level is difficult as this type of heater is driven by a pump. However, the system is very efficient.
5. Oil Pan Heater
This is a plastic pad that encloses a heating element. Just attach it to any metal part of your engine and it will heat up the entire engine. It’s better to attach it to the engine oil or the transmission oil pan. However, you could use two of these oil pan heaters to connect to both.
If you are using two oil pan heaters in your vehicle, always keep the power cables separate.
Although they are not as efficient as other types, they are easier to install and allows you to use on more than one vehicle.
6. Freeze Plug Heater
This is the good quality engine block heater in terms of efficiency. Every engine has a freeze plug and this is replaced by the freeze plug heater to warm the engine.
It directly warms up the coolant. It’s small in size but difficult to install. Especially if you have multiple cars to warm, this turns out to be tricky.
7. Cartridge Heater
To install a cartridge heater, the model of your vehicle should have space for it. This is usually found near the heard of the engine. Here, you can attach a cartridge heater with the help of a bracket. It comes in contact with one of the coolant channels and thus warms it up.
Installation of cartridge heaters is easy, taking only up to 15 minutes.
8. Drain Plug Heater
The nature of the drain plug heater is similar to the freeze plug heater. The only difference lies in the installation method. In the case of the freeze plug heater, the freeze plug of the engine is replaced by it. In this case, the drain plug of the engine block is replaced by the drain plug heater.
Frequently Asked Questions (FAQ)
1. Why Do I Need an Engine Block Heater?
Answer: If you live in extremely cold climates, especially in areas like North and South Dakota, Alaska, Montana, Wyoming, your car probably needs an engine block heater.
That’s because the freezing temperatures bring down the temperature of the engine. With an engine block heater, you protect your engine as it stays warm even when your truck is not running. If the oil is cold, it won’t flow through smoothly, harming your engine.
2. Which Type of a Block Heater Is Appropriate For My Vehicle?
Answer: You should choose the type of engine block heater that fits the engine size of your vehicle. Also, check how easy or hard the installation of the heater is before deciding to buy one. Another major important consideration is the weather.
3. Which Type of Engine Block Heater Is the Most Difficult to Install?
Answer: While most engine block heaters are fairly easy to install, the most difficult one is that which uses a pump to circulate warm coolant. The constant circulation prevents the coolant from getting frozen in winters.
Both circulating and non-circulating forms of in-line heater should be installed professionally.
4. If I Don’t Run My Vehicle Regularly, Do I Need an Engine Heater?
Answer: Even if you don’t run your vehicle daily, an engine warmer for winter will come to use. Many of us are into drag racing and we don’t use these cars often. As a result, they sit idle. When the engine is not running, it will wear and tear. Having an engine heater will prevent this.
5. How Do I Know When to Use an Engine Block Heater?
Answer: The first indication to watch out for is the weather. It will tell you if your car needs to be plugged into a heater or not. The antifreeze in your car should tell you that. If you see it’s not in its fluid state, then it’s better to have an engine warmer connected. Otherwise, your engine block may crack.
6. What Is Meant by Warming up the Car?
Answer: When you turn on the ignition and let the car sit idle with the engine running for a while, you’re warming up your car. It’s important because your engine has been sitting inactive and the coolant, oil, and other fluids are not sufficiently warm to start driving.
7. Which Is the Least Efficient Type of Engine Block Heater?
Answer: The oil pan heater is the least efficient type of engine block heater. That’s owing to the roundabout way of warming the coolant of your engine. It takes a long time for the oil to be warmed and then transferred to the pan and to the engine.
8. How Do I Locate the Block Heater Cable in My Car?
Answer: To locate the cord for the block heater in your vehicle, look at the grille of the car. You might see it hanging from there. If it’s not there, then check inside the hood of your car.
Vehicles are one of the most important parts of modern life. But oftentimes, we only look at the outside of the vehicle and take care of the exterior. Taking care of the vehicle engine should be number one on the list for car care.
This is especially applicable for denizens of cold and dry climates. When vehicles are left to rest overnight, it becomes difficult to get them to start the next day.
That’s why engine block heaters are the perfect solution. They help to prevent damage to the engine and save money in the long run.
To help you know more about why you need one and to enable you to select the best engine block heater, we have compiled a list. User reviews have also been factored in. We hope this helps you in hunting for the right engine warmer before the next bout of winter hits you.
