Important: The oil pan must be installed within 5 minutes of the sealer being applied or the sealer will begin to cure, causing an inadequate seal.

1. Apply sealant GM P/N 12346286 (Canadian P/N 10953472), or equivalent to the sides of the front (2) and rear (1) crankshaft bearing caps, on both the left and right sides (4 locations total).



2. Install a NEW oil pan gasket into the oil pan groove, if required.
3. Install the oil pan.



4. Install the oil pan bolts until snug.




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.
