Installation
All vehicles
1. Position the engine front cover gasket on the engine front cover..
2. NOTE: If the engine front cover is not secured within four minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or four minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
Apply the silicone gasket and sealant along the cylinder head-to-cylinder block surface and the oil pan-to-cylinder block surface.
