Exhaust Manifold Cleaning and Inspection






Important: Do not reuse exhaust manifold-to-cylinder head gaskets. Upon installation of the exhaust manifold, install a NEW gasket.

1. Clean the exhaust manifold in solvent.

Caution: Refer to Safety Glasses Caution in Service Precautions.

2. Dry the exhaust manifold with compressed air.
3. Inspect the exhaust manifold-to-cylinder head gasket surface for excessive scratches or gouging.
