What do engine block heaters do?
Mia Phillips updates
Engine block heaters are devices used to warm the engine and fluids before starting a vehicle. In bitter cold temperatures, heaters are useful because they reduce the risk of damage from "cold starts" and idling. When the car is started after using a heater, fluids quickly reach an ideal operating temperature.
