The Importance of a Block Heater
What is a block heater?
Engine block heaters are devices for warming up your engine, oil and engine coolant in cold weather. These heaters are mounted in the area surrounding the cylinder or against the engine block and can be plugged into standard household outlets. Engine block heaters help enable faster and easier starts during winter when an engine might not normally turn over.
How does a Block Heater Work?
A block heater is used to assist an engine in starting, particularly in cold weather climates. They are typically found on diesel engines to preheat the glow plugs before engine start up, but are used on all engine types in extreme cold weather situations.
How to test a block heater?
A block heater is a built-in heating device to keep your engine block warm. This is especially useful in northern climates to give you almost instant heat during chilly morning start-ups. Block heaters are essential for any diesel-engine vehicle to aid in cold-weather starting. However, because they are encapsulated within the engine itself, the only external part will be a typical electrical cord and plug. But that by itself will allow you to test and see if your block heater is working.
Why use a block heater?
For people who live in cold climates, a block heater for their car is practically a necessity. Block heaters reduce the chances of the car failing to start when the temperature is below freezing, shortening warm-up time and even improving mileage.
