  1. Ensure the engine is off, cool, and disconnected from the battery.

  4. Thoroughly clean both mating surfaces, removing all old gasket material and sealant residue.
  5. Position the new gasket, confirming it aligns correctly with all bolt holes and passages.
  6. Reassemble the engine components, tightening all fasteners to the manufacturer-specified torque and sequence.
  7. Refill any drained fluids to their proper levels.
  8. Reconnect the battery, start the engine, and meticulously check for any leaks around the newly installed gasket.

Troubleshooting & FAQ

How do I know if this gasket will fit my specific Volvo Penta engine?

The best way to confirm fitment is by matching the part number. This gasket replaces Volvo Penta part number 859027. Since detailed model compatibility is not provided, you must verify this number against your engine's service manual or the old part itself.

What are the common signs of a failed engine gasket?

Symptoms of a faulty gasket can include visible fluid leaks (oil or coolant) around the engine, engine overheating, loss of compression, or milky-colored oil, which indicates coolant is mixing with the oil.

Why is this a "special order item"?

Special order items are typically parts that are not held in our regular stock due to lower sales volume or specific sourcing requirements. This may result in a longer lead time for delivery.

Is any sealant required for installation?

Whether a sealant is needed depends on the specific application and the type of gasket. Always consult your engine's service manual. Some gaskets are designed to be installed dry, while others require a specific type of sealant on one or both sides.

What does the California Proposition 65 warning mean?

This warning indicates that the product may contain chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information, you can visit the OEHHA website for Prop 65.
