Installation Notes

Ensure the engine is completely cool and disconnect the battery as a safety precaution.
Drain the engine coolant to prevent spills.
Carefully disconnect spark plug wires and remove any components obstructing access to the cylinder head.
Loosen and remove the cylinder head bolts in the reverse sequence recommended by the manufacturer to prevent head warping.
Remove the old gasket. Thoroughly clean the surfaces of both the cylinder block and the cylinder head, removing all old gasket material and residue.
Position the new head gasket correctly, ensuring any markings like "UP" or "TOP" face the cylinder head.
Reinstall the cylinder head and tighten the bolts to the factory-specified torque and sequence. This is critical for a proper seal.
Reassemble all previously removed components, refill the cooling system, and reconnect the battery.
Start the engine and let it warm up, checking carefully for any coolant, oil, or compression leaks.

Troubleshooting & FAQ

How can I tell if my head gasket is failing?

Common symptoms of a blown head gasket include engine overheating, white smoke from the exhaust (burning coolant), milky or foamy oil, unexplained coolant loss, or a loss of engine compression and power.

Will this gasket fit models outside the listed year range?

We can only guarantee compatibility for the models and years specified in the compatibility table. Using this part on other models is not recommended, as even minor differences in engine design can cause leaks or engine damage.

Is any sealant required during installation?

Most modern head gaskets, including this one, are designed to be installed dry without any additional sealants. Applying sealants can interfere with the gasket's ability to create a proper seal. Always follow the engine manufacturer's service manual for specific instructions.

Can I reuse my old cylinder head bolts?

It is strongly recommended to use new cylinder head bolts, as old bolts can stretch and may not provide the correct clamping force when retorqued. This can lead to premature gasket failure. Please consult your service manual for bolt specifications.

What is the difference between this and an OEM gasket?

Our aftermarket gasket is manufactured to the same specifications and performance standards as the original OEM part. It offers a cost-effective solution without compromising on quality, materials, or fitment.

OEM vs. Aftermarket?

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

Shipping speed & cost?
