⚙️ Key Features

- Designed for the corresponding OEM filler-neck assembly
- Protects the system from dirt and moisture
- Provides secure closure during engine operation
- Correct OEM thread or locking profile
- Direct replacement for cap 21385502
🔌 Function
The cap seals the filler opening and prevents fluid loss, dirt entry and moisture contamination. A sound cap also ensures that the filler neck remains securely closed under vibration and normal engine operating conditions.
⚠️ Common Signs of Failure
- Fluid seepage around the cap
- Cap loosening during engine operation
- Damaged sealing face or internal seal
- Cracked or distorted cap body
- Corroded locking surfaces or threads
- Dirt or moisture entering through an incomplete seal
🛠️ Service Notes
- Fit the cap specified for that filler on your engine — caps that look alike differ in seal, venting and pressure rating, and a substitute may hold the system at the wrong pressure or not seal at all
- Wipe the filler neck and check its sealing land for nicks, corrosion and distortion before fitting; many apparent cap leaks are actually neck leaks
- Check the cap's seal is soft and unbroken, and that any vent or breather hole through the cap is clear
- Seat the cap fully, to its stop or lock position — a cap left part-turned will weep, and on a pressurised system can lift
- Never open a cap on a hot pressurised system; let it cool first
