Serial Number Fitment Notice

When This Part Needs Replacement
Replace the oil filter during scheduled oil changes, seasonal maintenance, winterization, or any time the filter is damaged, leaking, restricted, corroded, or overdue for service. A clean oil filter helps reduce abrasive contamination in the lubrication system and supports reliable engine operation.
Installation Notes
Install according to the Volvo Penta service manual for the specific engine. Clean the sealing surface, lightly oil the new filter gasket, spin the filter onto the original filter mount by hand, and tighten as specified. After refilling with the correct engine oil, run the engine, check carefully for leaks, shut down, and recheck the oil level before returning the engine to service.
