Auxiliary Diesel Pre-Heater Control Valve | LR016848

A diesel engine pre-heater manages coolant from the engine’s cooling system to be routed through an internal network of passages within the heat exchanger. As the coolant flows through this system, the heat from the exhaust is transferred to the coolant which is then routed back to the diesel engine. The heated coolant then transfers its heat to the cold engine as it circulates, thus, greatly decreasing the time required to bring the engine up to operating temperature.
