Troubleshooting & FAQ
How do I know if this gasket fits my specific engine model?
This gasket is designed for a broad range of Volvo Penta 2.0L to 7.5L gasoline engines. The best way to confirm fitment is to match your existing part number to one of the numbers listed in our Part Number Matrix (859091, 3860692, etc.). You can also consult your engine's service manual.
What are the typical symptoms of a faulty intake manifold gasket?
Common signs include a rough idle, engine misfires, unexplained coolant loss, engine overheating, or a visible coolant leak around the intake manifold. You may also notice poor fuel economy and a decrease in overall engine power.
When should this gasket be replaced?
This gasket should be replaced whenever the intake manifold is removed for other service, or immediately if you notice symptoms of failure. There is no set replacement interval; it is typically replaced on an as-needed basis.
Can I reuse my old manifold bolts for the installation?
It is generally recommended to use new bolts, especially if they are torque-to-yield (TTY) bolts, as they can stretch and may not provide the correct clamping force when reused. Always consult your service manual for the manufacturer's recommendation.
