Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: Apply sealer GM P/N 12346004 (Canadian P/N 10953480) or equivalent to the shaded bolts (1) in the graphic. Failure to do so may result in engine coolant leakage from the bolt holes passing through the water jacket.

Tighten
Tighten the front cover bolts to 25 N·m (18 lb ft).
