Product Details

This Four Seasons heater valve is part of the Heater Valve line and is engineered for vehicles that use a cable-actuated coolant shutoff at the heater circuit.

Common Problems It Can Address

Match the hose connector count and opening size to the original part, and inspect heater hoses, clamps, and cable routing during replacement. After installation, refill and bleed the cooling system according to factory service procedures to remove trapped air and confirm normal heater operation.
