Basic Climate Control Heating System
Heating System
•
To warm the passenger compartment during cold weather the heat from the engine is
indirectly used. The heat is transferred to the engine coolant, and the engine coolant
passes through the heater core in the passenger compartment, which gives the heat up
to the incoming air. The coolant circulates in two circuits, the ‘small’ and the ‘big’ circuit.
In the small circuit, the water pump circulates the coolant past the engine and through
the heater core. In the ‘big’ circuit, the thermostat opens allowing the radiator to transfer
the captured heat to the passing air.
