Engine Compatibility
Current references support Volvo Penta 3818912 in D4 and D6 diesel cooling-system applications. The strongest catalog trail places it in the D6-280A-A cooling system, while broader current fitment sources associate it with multiple D4 and D6 water pump applications. The safest fitment standard is the exact Volvo Penta parts diagram for the engine being serviced, especially when confirming coolant-pump configuration by serial number.
Serial Number Fitment Notice
Fitment can vary by engine rating, production revision, and pump version. Confirm Volvo Penta part number 3818912 against your engine serial number and the correct cooling-system diagram before ordering to ensure it matches the exact pump assembly on your engine.
When This Part Needs Replacement
Replace this gasket whenever the water pump or coolant pump assembly has been opened, or when the original gasket shows coolant seepage, flattening, tearing, swelling, or damage during removal. Replacing it during pump service is usually the safer choice than reusing an old compressed gasket.
Installation Notes
Install on clean, flat mating surfaces with all old gasket material removed. Confirm the gasket matches the exact pump housing and diagram location before assembly, and tighten related hardware evenly to help prevent repeat coolant leaks. Since 3583811 updates to 3818912 in current references, matching either number during service can help confirm you have the correct gasket.
Alternate/Superseded Part Numbers
Current Volvo Penta parts references show 3583811 as the earlier number updated to 3818912. Use 3818912 as the current primary OEM ordering number.
Parts Desk Insight
Water pump gaskets are easy to underestimate because the old one can still look usable once removed. Matching the exact D4 or D6 cooling-system diagram first usually saves more time than trying to compare the old gasket by shape alone.
