Heater Valve Replacement Cone Set — BMW E39 / E38 / E34 / E46 and Mercedes-Benz W140 / W124
Restore Proper Valve Seating — Replace the Worn Cones Without Buying a New Valve.
The cone valves inside BMW and Mercedes heater control valves wear over time — causing poor seating, coolant leaks, and loss of temperature control. This cone set replaces the worn cones precisely, restoring a proper seal and full valve operation.
Verify Your Valve P/N Before Ordering. Compare the cone dimensions with your existing cones before purchasing.
