🔌 Function
Seals the filler neck and holds the cooling system at its working pressure, lifting to pass coolant to the expansion tank and drawing it back as the engine cools.
⚠️ Common Signs of Failure
- Coolant loss with no leak found, and the expansion tank overfilling
- Engine running hot or boiling in the header tank
- Top hose collapsing as the engine cools
- Seal rubber hardened, cracked or swollen
- Weak or corroded pressure spring found when the cap is tested
🛠️ Service Notes
- Test or simply renew the cap before chasing a pressure or overheating fault elsewhere - it is the cheapest part in the circuit and a common cause
- Check the filler neck seat and sealing face for corrosion or damage while the cap is off
- Never open the cap while the system is hot and pressurised
