Engine Block Heater

The engine block heater is located in the engine coolant system and is responsible for warming the coolant throughout the engine block, cylinder head and around the cylinders liners. The block heater is powered by an external 120v or 220v power source with varied amperage ratings.

Engine Electric Pre-heater

The pre-heater is located at the inlet of the engine intake manifold and powered by the vehicle’s 12v electrical system. When ambient air temperature is below 54ºF the pre-heater will engage, heating the air as it enters the manifold. Once the engine has started, the pre-heater will typically remain active for 25 to 50 seconds.

Oil Pan Heater

The oil pan heater is used to heat the engine oil while the vehicle is stationary. The oil heater is powered by an external 120v source.

When an engine block heater and oil pan heater are ordered together, the wiring for both systems are integrated into the external power supply connector.

When a 1500 watt engine block heater is selected in conjunction with the oil pan heater, the vehicle harness receptacle will be equipped with a NEMA 120V-20amp “Industrial Plug” in place of a NEMA 120V-15amp “Household Plug”.
