🔌 Function

Provides the sealed, pressure-rated filling point for the fresh water circuit and gives the pressure cap its seat.

⚠️ Common Signs of Failure

• Coolant weeping or spitting from around the cap
• Cap will not hold pressure or blows off early
• Corroded, pitted or distorted sealing seat
• Steam or a sweet smell over the front of the engine when hot
• Repeated coolant loss with no visible leak elsewhere

🛠️ Service Notes

• Plate 3825402 carries the same serial breakpoint of 1101051559 and belongs to the same later build, so check both when working on the header tank
• Fit a new pressure cap and seal with the neck, as a worn cap will fail a good neck's seat
• Check the seat for pitting before blaming the cap for pressure loss

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
