🔌 Function

Seals the filler and holds the cooling system at its working pressure, relieving to the expansion side when that pressure is exceeded.

⚠️ Common Signs of Failure

• Coolant loss and steam at the filler with no other leak found
• Overheating that eases as soon as the cap is slackened
• Sealing rubber hard, cracked or swollen
• Sealing face pitted or scaled
• Spring gone soft, so the cap lifts far too early

🛠️ Service Notes

• Quote specification 867521 or 867527 when ordering, as this number covers both
• Because the earlier numbers were listed as a cover and as a housing, an old parts list may not use the word cap at all
• Never open a hot system, and pressure test the circuit once the new cap is on
