Parts Desk Insights
Best Use Case: This gasket is the correct replacement when the original is found damaged, compressed, or leaking during engine service or component disassembly. As a general rule, any gasket that has been disturbed during service should be replaced — reusing a compressed or deformed gasket is one of the most common causes of repeat leaks after a repair.
Common Issues: Gaskets are one of the easiest parts to mis-order because many Volvo Penta gaskets look similar in photos. The safest approach is to confirm part number 21584008 directly against your engine serial number and the relevant diagram position. If you have the old gasket in hand, the part number is often stamped or printed on it. Contact us with your engine model and serial number if you need help confirming the correct part before ordering.
Installation Notes
Always replace gaskets rather than reusing them. Clean mating surfaces thoroughly before installation and inspect for warping or damage. Use the torque specifications from your Volvo Penta service manual for all fasteners. Do not reuse the old gasket.
Service Interval
Gaskets are not a scheduled replacement item. Replace whenever the mating component is disassembled for service, or when a leak is traced to the gasket location. Inspect adjacent seals and O-rings at the same time and replace as needed.
Technical FAQ
Q: How do I confirm this is the right gasket for my engine?
A: Cross-reference part number 21584008 against your engine model and serial number in the Volvo Penta parts diagram. If you have the old gasket, check for a part number stamped on it. Contact us with your serial number if you need help confirming.
Q: Can I reuse the old gasket if it looks okay?
A: No — Volvo Penta recommends replacing gaskets any time they are disturbed. A gasket that has been compressed and released will not seal reliably and is a common source of repeat leaks.
Q: Should I replace other seals and O-rings at the same time?
A: Yes — whenever a component is disassembled, it's best practice to replace all gaskets, seals, and O-rings in the assembly. This avoids having to re-open the engine shortly after for a seal that was borderline at the time of service.
