Installation Notes

Disconnect the battery and allow the engine to cool completely. Drain the engine coolant.
Remove any components obstructing access to the cylinder head, such as the intake and exhaust manifolds.
Carefully unbolt and remove the cylinder head, followed by the old gasket.
Thoroughly clean and inspect the mating surfaces of both the engine block and the cylinder head. Ensure they are free of debris and old gasket material.
Position the new cylinder head gasket, paying close attention to its correct orientation.
Reinstall the cylinder head. Tighten the head bolts in the sequence and to the torque values specified by the manufacturer.
Reassemble all previously removed components, refill the cooling system, and reconnect the battery.
Start the engine and check for any coolant, oil, or compression leaks.

Troubleshooting & FAQ

How do I confirm this gasket fits my engine?

This gasket is specifically made for Volvo Penta D1-13, D1-13B, and D1-13F engine models. The best way to ensure fitment is to check the part number (3809647 or 3808602) from your engine's service manual and compare it to this listing.

What are the common signs of a failing cylinder head gasket?

Symptoms of a blown head gasket include engine overheating, white smoke from the exhaust (burning coolant), milky or frothy engine oil, unexplained coolant loss, and poor engine performance or loss of compression.

Why are two part numbers (3809647 and 3808602) listed?

Manufacturers often update part numbers over time. In this case, 3809647 is a newer number that supersedes the older 3808602. Both refer to the same component with identical specifications for the listed engines.

Is this gasket made from the same material as the original?

This aftermarket gasket is manufactured to meet or exceed OEM specifications, using comparable, high-quality materials suitable for the high-pressure, high-temperature environment of a marine diesel engine.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
