Troubleshooting & FAQ
How do I know this is the right gasket for my engine?
Verify your engine model and year against the compatibility table. This gasket is specifically for Volvo Penta D2-55 and D2-75 series engines and directly replaces OEM part number 21228429. Comparing your old part to our photos is also a crucial verification step.
What are the signs of a failing cylinder head gasket?
Common symptoms include engine overheating, white smoke from the exhaust (coolant burn-off), milky or discolored engine oil (coolant contamination), and coolant loss with no visible external leaks. You may also experience loss of compression or poor engine performance.
Do I need to use sealant with this gasket?
No. This gasket is designed to be installed dry. The mating surfaces on the engine block and cylinder head must be perfectly clean, flat, and free of any old material or oils. Using sealant can interfere with the seal and cause premature failure.
What is the difference between this part and the superseded number 3809337?
Part number 21228429 is the current, updated replacement for the older 3809337. It may feature incremental improvements in materials or construction to enhance durability and sealing performance while maintaining the exact same fit and function.
