(1) Heater core Coolant is circulated throughout the system by the water pump. Coolant circulates through heater core (1) in order to exchange heat with the air inside the cab. The heater core is constructed of copper or aluminum. Copper and aluminum are utilized in the design because these metals are excellent conductors of heat. Foreign matter on the outside surface of the heater core can cause a poor exchange of heat. The heating system loses the capability to heat when the heater core gets dirty. The outside surface of the heater core should be cleaned when the system is checked.
