Installation guide - Replacing a radiator cap
General guidance for this part type - always follow your device manual- Rag
- Match the pressure rating stamped on the old cap.
- 1Let the engine cool. Switch the engine off and wait until it is completely cold. Never open a cap on a hot engine; the coolant is under pressure.
- 2Remove the old cap. Cover it with a rag, press down and turn it counterclockwise slowly to the first stop, let any pressure out, then remove it.
- 3Check the filler neck. Wipe the sealing surface clean and check the coolant level.
- 4Fit the new cap. Press it down and turn it clockwise until it locks fully.
- 5Check for leaks. Run the engine to normal temperature and look for seeping coolant around the cap.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
