An engine block heater is an electric device that helps preheat a vehicle’s engine during cold weather.
It is typically installed in the engine block and heats the coolant, which in turn warms the engine’s internals. This helps reduce engine wear, improve fuel efficiency, and facilitate easier cold starts in freezing temperatures.
