Installation Guide

1. Remove the old gasket and clean the mating surfaces on both the exhaust manifold and cylinder head with a solvent to eliminate residue.
2. Inspect the surfaces for scratches or damage; repair if necessary before proceeding.
3. Place the new ELRING 690.721 gasket onto the manifold, aligning it precisely with the bolt holes.
4. Reattach the cylinder head, tightening bolts in a cross‑pattern sequence to ensure even pressure distribution.
5. Verify that all fasteners are torqued to the manufacturer’s specifications.

Maintenance & Longevity Tips

• Inspect the gasket during routine maintenance or after any engine overhaul.
• Avoid exposing the gasket to extreme temperatures beyond its rated range; use a heat shield if necessary.
• Keep the exhaust system clean from corrosive deposits that could degrade gasket material over time.
