【Function】Engine block heaters are devices used to heat the engine and fluids before starting the vehicle. Heaters are useful in cold temperatures because they reduce the risk of "cold start" and idling damage. When the vehicle is started after using the heater, the fluid quickly reaches the ideal operating temperature.
