1357776 Locating Ring | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta cooling-system filler cap catalogued under part number 1357776. The pressure cap closes the expansion tank or heat-exchanger filler neck and maintains the designed cooling-system pressure while allowing excess pressure and coolant recovery through its internal valve.

🚤 Compatibility

• HP Range: Approximately 120-171 HP
• Year Range: Approximately late 1970s - 1990s

⚙️ Key Features

• Genuine Volvo Penta OEM coolant filler cap
• Correct Volvo Penta part number 1357776
• Pressure-regulating expansion-tank cap
• Cross-references with Volvo automotive and branded aftermarket caps
• Suitable for selected fresh-water-cooled red-block marine engines
• Engine type: Volvo Penta inline 4-cylinder fresh-water-cooled petrol engine

🔌 Function

The cap seals the filler neck and raises the coolant boiling point by maintaining system pressure. Its internal valves release excess pressure and admit coolant or air during cool-down.

⚠️ Common Signs of Failure

• Coolant escapes around the cap or overflow connection
• Engine overheats despite correct coolant level
• Upper hoses remain collapsed after cool-down
• Cap seal is cracked, hardened or swollen
• Spring valve is corroded or no longer holds pressure

🛠️ Service Notes

• Despite being catalogued under 'Locating Ring', this part is the cooling-system pressure cap — check the pressure rating stamped on the cap matches your system before fitting, since caps of different ratings are not interchangeable even where they physically fit the same neck.
• It cross-references several older numbers (1357775, 1274100, 410655) — if matching a cap already fitted, check which of those is on the engine rather than assuming from the tank or hose fitting alone.
• Confirm the internal valve holds by pressure-testing the cooling system after fitting rather than by sight; a cap that looks sound can still fail to hold pressure, which shows up only as gradual coolant loss with no visible leak.
