Mercedes-Benz Heater Valve Insert (Spool) - A0008350644

This insert is the internal spool component for the heater control valves identified below in the listed Mercedes-Benz applications. Match the installed valve reference and insert design before choosing the replacement.

Vehicle Applications

• Mercedes-Benz С107 1971-1989
• Mercedes-Benz R107 1971-1989
• Mercedes-Benz W123 1979-1991
• Mercedes-Benz W126 1979-1991
• Mercedes-Benz W107.

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.

Insert and Related References

The full insert, valve and related reference list is in Part Number / PN. Match the installed assembly; the reference list does not imply unrestricted interchange between every valve version.

Repair Scope

The product is the heater valve insert. Inspect the valve housing and electrical section before replacing internal components; a damaged housing or solenoid may require a different repair. Heating symptoms alone do not identify the insert as the failed component.

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.
