Heater Core
Mitsubishi FUSO®

The Heater Core, also known by its part number MK583351, is an essential component of a truck's heating system. It is responsible for converting hot engine coolant into warm air that is blown into the truck's cabin through the vents. The Heater Core works by passing the hot coolant through a series of small tubes that are surrounded by fins. As air flows over these fins, it absorbs the heat and is then distributed throughout the cabin. If the Heater Core becomes clogged or damaged, it can lead to a lack of heat in the cabin or even coolant leaks. Replacement of a faulty Heater Core is crucial for maintaining proper heating function in a truck.
