Heating Symptoms to Diagnose

• Only hot air from the heater.
• Only cold air from the heater.
• Cabin temperature cannot be adjusted.
• Different air temperatures on the left and right.
• Weak cabin heating in winter.
• Coolant leakage through the heater valve.

Confirm the cause before replacing seals. A seal repair can address leakage caused by worn seals when the valve housing and solenoids are serviceable; cracks or other damage may require a different repair.

Important Before Ordering

Compare the original part number, marking, shape and mounting design before ordering. A model name alone does not confirm the required version.

FAQ

No. It contains seals only.

Can it repair a cracked valve housing?

A cracked housing can require replacement of the valve assembly; inspect it before choosing a seal repair.

How should I select the kit?
