Troubleshooting & FAQ
How do I confirm this head gasket fits my specific engine?
This part is a direct replacement for Fel-Pro 17040. Because detailed engine model compatibility is not available, it is critical to compare the photos, dimensions (68.0" x 28.0" x 0.2"), and material specifications to your original part before ordering.
What are the common signs of a failed head gasket?
Common symptoms include significant loss of engine power, engine overheating, white smoke from the exhaust (indicating burning coolant), milky or foamy engine oil, and bubbling in the radiator or coolant reservoir.
Can this head gasket be reused?
No. Head gaskets are designed for one-time use only. They create a seal by being compressed ("crushed") to exact specifications. Reusing a gasket will almost certainly result in leaks and improper sealing.
