Diesel engine block heater

The engine block heater is used on diesel vehicles in cold weather, to keep the engine from freezing. This heater mounts directly to the engine in place of a freeze plug or a pipe plug. Engine block heaters can be installed in a hour or two. Before you turn on the heater, you should fill the engine with coolant, and test the engine. To get the block to heat the engine you plug a block heater cord into a outlet. A cold diesel engine can make the vehicle hard to start up, and it decreases your battery output amperage.
