How to Install a Block Heater in Your Car

Eric Loveday
As the mercury dips to near zero in many regions, we quickly realize that these freezing temperatures have a profound impact on our most common mode of transportation, our car. Cars perform best in warm weather. The fluids used to lubricate the car flow freely, the battery provides more starting power, and the heating system is adequate when temperatures are above freezing. However, since the cold weather is upon us, we need to prepare our cars for the months ahead. Installing a block heater is an excellent way to ward off the effects that the cold weather has on our cars.

Block heaters install into the coolant passages of a car and through the use of electricity, provide warming of the entire engine as well as anything attached directly to the engine of the car. A block heater contains a small electric heating element that warms the coolant in the car which in turn warms the rest of the car. Block heaters range in price from as little as $20 to as much as $100 depending upon the wattage that you purchase and the type that your vehicle requires. Most block heaters are easy to install, though I recommend a professional handle the installation of this item.

You can usually purchase a block heater for your specific car from the dealership. If the dealership does not have one in stock, the can usually order it for you. Most new cars sold in Canada and Alaska come standard with block heaters so finding one that will work for your car should not be difficult. Though people who live in very cold regions such as Alaska are familiar with block heaters and their benefits, those living in warmer regions like the Midwest and the Northeast could benefit greatly from a block heater.

Once you have chosen a block heater for your specific car and have it installed you will be able to immediately enjoy the benefits. All you need to do is purchase an outdoor timer and plug the cord from the block heater into it each night during cold weather. Set the timer to turn on approximately two hours before you have to leave for work in the morning. The block heater will automatically turn on and begin to warm the coolant and your entire engine. By the time you are ready to leave, you will realize that the entire engine bay area is warm and the car will start much easier. Another benefit that you will quickly realize is that your car will blow hot air through the heater vents almost instantly after starting the car. This could be extremely beneficial to those that have waited several minutes feeling nothing but ice cold air come out of the heater vents inside your car.

So go ahead and install a block heater in your car. Your car will thank you with much easier start and reduced wear and tear and you will be happy with the instant heat that blows through the heater vents making those bitterly cold days bearable.

    Just stick one end into the other end, and then stick the other end into the other end.., and that should do it! Be carefull not to confuse the ends, or leave any ends unended. Be sure you torque all values as per OEM specs.
