          The heater control valve is one of the many components that are responsible for warming the interior compartment. This valve allows hot coolant to be piped directly from the engine to the heater core. The heater core then transfers the heat to the interior compartment by recirculating air from inside the car across the heater core fins. This continued cycle of heating the air inside the vehicle is extremely efficient.
