Troubleshooting & FAQ
How can I confirm this gasket fits my specific engine?
The most reliable method is to match the OEM part number 859034. You can also use the compatibility table to verify your engine model and year range. When in doubt, compare the product images to your old part.
Is this an "intake manifold gasket" or an "aftercooler gasket"?
Both terms are often used for this part depending on the specific engine diagram and terminology. It seals the connection for the intake manifold, which may incorporate an aftercooler (intercooler) on these Volvo Penta models.
What are the signs of a failing intake manifold gasket?
Common symptoms include external coolant leaks, engine overheating, poor performance or rough idling, and loss of boost pressure on turbocharged models. A visual inspection may reveal coolant residue or gasket degradation.
Do I need to use gasket sealant with this part?
Typically, this type of gasket is designed to be installed dry. Applying sealant can sometimes interfere with a proper seal. Always consult your official Volvo Penta service manual for model-specific instructions.

This listing is for an aftermarket replacement, not an OEM component. It has been engineered to meet or exceed original equipment manufacturer (OEM) specifications for material and performance, manufactured in an ISO 9002 certified facility, and is subject to batch inspection for quality assurance.
