Engine Compatibility

This sealing ring is shown in Volvo Penta charge air cooler diagrams for select D9A2A and D9A2B diesel engine applications, including D9-425, D9-500, D9-575, and related D9A marine / industrial configurations depending on serial number and charge air cooler assembly. Supporting gasket-set references also associate 3807481 with D9A2A / D9A2B / D9A2C / D9A2D / D9A2E / D9A2F / D9A2G / D9A2H / D9A2J / D9A2K / D9A2L / D9A2M and selected D11 configurations, but the strongest match is by the exact charge air cooler diagram callout.

Serial Number Fitment Notice

Sealing ring fitment depends on the exact Volvo Penta engine model, charge air cooler assembly, flange connection, cooling-system layout, and serial number range. Always confirm compatibility using the Volvo Penta engine serial number and current parts diagram before ordering, especially on D9 engines where charge air cooler configurations can vary by rating and production range.

When This Part Needs Replacement

Replace this sealing ring whenever the related charge air cooler connection is opened, or if the original seal is flattened, hardened, cut, swollen, leaking, heat-damaged, or no longer sealing properly. Reusing an old compressed sealing ring can lead to air or coolant-side leakage depending on the service location.

Installation Notes

Clean the sealing surfaces before installation and inspect the charge air cooler flange connection, O-rings, end plates, anode, drain nipple, and related hardware while the assembly is apart. Seat the sealing ring evenly and follow the Volvo Penta service procedure for the specific D9 / charge air cooler assembly.

Parts Desk Insight

This is a diagram-specific charge air cooler seal, so the safest match is the exact Volvo Penta parts drawing rather than engine family alone. If the charge air cooler is already apart, checking the adjacent O-rings, anode, flange connection, and drain hardware at the same time can help prevent repeat service.
