🔌 Function

Holds the cooling system at its working pressure so the coolant can run above its atmospheric boiling point, and releases into the expansion tank when the pressure rises past its setting.

⚠️ Common Signs of Failure

• Coolant pushed out into the expansion tank or overboard on every run
• Boiling or overheating with the coolant level correct
• Seal on the cap perished, swollen or missing
• Coolant staining around the filler neck
• Cap no longer holding when the system is pressure tested

🛠️ Service Notes

• Check the filler neck seat and sealing face when the cap is changed - a damaged neck will leak past a new cap
• Never open the cap while the engine is hot
