Troubleshooting & FAQ
How can I confirm this gasket fits my engine?
The most reliable method is to match the part number. This gasket replaces Volvo Penta 957181, 18840, and 1218022. Always compare the photos and specifications to your old part before ordering.
What are common signs of a failed engine gasket?
Signs of a failing gasket include visible fluid leaks (oil or coolant), engine overheating, loss of compression, or discolored engine fluids. If you notice any of these symptoms, inspect your engine's seals promptly.
Is any sealant required with this gasket?
Typically, modern gaskets are designed to be installed dry. However, always consult your engine's service manual for specific instructions, as some applications may recommend a light application of a specific sealant.
How often should engine gaskets be replaced?
Gaskets do not have a fixed replacement interval. They should be replaced whenever a component is removed or if there are any signs of leakage or failure.
Can I reuse my old gasket?
No. Gaskets are single-use components designed to crush and create a seal. Reusing an old gasket will likely result in leaks and improper sealing.

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.
