(20) Heater core (32) Water valve (M) Actuator motor (water valve)Heater core (20) circulates water 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. Heater core (20) and water valve (32) are connected with a heater hose. These connections are critical. These connections should be checked for leaks periodically. Water valve (32) is controlled by actuator motor (M). This water valve controls the amount of water that flows into heater core (20). 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.
