Installation





1. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.

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.

NOTE: Make sure that the engine front cover gasket is in place on the engine front cover before installation.

Apply silicone gasket and sealant along the cylinder head to cylinder block surface and the oil pan to cylinder block surface.





2. Install the engine front cover with engine front cover gasket on the front cover to cylinder block dowel and loosely install the bolts.











3. Tighten the engine front cover fasteners in sequence in two stages.
Stage 1: Tighten fasteners 1 through 7 to 20 - 30 Nm (15 - 22 ft. lbs.).
