- Carefully lift the cylinder head from the engine block and remove the old gasket.
- Thoroughly clean and inspect the mating surfaces of the engine block and cylinder head. Ensure they are flat, clean, and dry.
- Position the new gasket correctly on the engine block; do not use any sealant.
- Carefully lower the cylinder head onto the gasket and block.
- Install new or verified head bolts. Lubricate threads as per the manual and tighten in multiple stages, following the manufacturer's torque sequence and values precisely.
- Reinstall all previously removed components.
- Refill the cooling system with the appropriate coolant, check oil level, and reconnect the battery before starting the engine.
Troubleshooting & FAQ
How do I know if my cylinder head gasket has failed?
Common signs include engine overheating, white smoke from the exhaust (coolant burning), milky or frothy engine oil (oil/coolant mixing), bubbles in the radiator or coolant reservoir, and unexplained coolant loss.
Does this gasket require sealant upon installation?
No. This is a multi-layer steel (MLS) gasket with a non-stick coating designed for a dry installation. Applying sealants can interfere with its function and cause premature failure.
Can I reuse my old head bolts?
It is strongly recommended to use new head bolts, as many are torque-to-yield (TTY) and stretch permanently upon first use. Reusing them can lead to improper clamping force and gasket failure. Always consult your service manual.
Is this gasket compatible with both Vortec and non-Vortec heads?
This gasket is primarily designed for 1997 and newer engines, many of which use Vortec-style heads with an 8-bolt intake manifold. Always verify your specific engine requirements and part numbers before purchase.

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.
