When to Inspect the Heater Valves

• The heater blows only hot air.
• The heater blows only cold air.
• Cabin temperature cannot be adjusted.
• Left and right air temperatures differ.
• Cabin heating is weak in winter.
• Coolant leaks through the heater valve.

Check the heater valve block to establish the cause. These symptoms do not identify a failed cone or sealing component by themselves.

Repair Scope

The internal repair components can be serviced while retaining a sound housing and serviceable solenoids. Worn seals can cause coolant leakage; inspect the housing because cracks may require replacement of the complete unit.

Important Before Ordering

Compare the installed heater valve OEM/P/N, marking and physical design with the listed references. Different valve versions may be fitted to the same vehicle model.
