Troubleshooting & FAQ
How do I know if this gasket fits my engine?
This gasket is a direct replacement for Volvo Penta part number 856004. It is crucial to verify this part number against the one specified in your engine's service manual or by checking the number on your existing part. Do not rely on model compatibility alone.
