Installation Procedure
- Install a NEW engine front cover. Refer to Engine Front Cover Installation .
- Clean all the adhesive from the corners of the oil pan gasket where it meets the engine front cover.
- Apply a 5 mm (0.197 in) wide and 25 mm (1.0 in) long bead of adhesive, GM P/N 12346141 or equivalent, to the engine front cover to engine block junction at the oil pan sealing surfaces.
- Install the engine oil pan nuts and bolts.
- Tighten the oil pan bolts to 12 N·m(106 lb in).
- Tighten the oil pan nuts to 25 N·m(18 lb ft).
- Connect the crankshaft position (CKP) sensor wire.

Important: The oil gasket and the oil pan must be installed and the fasteners tightened while the adhesive is still wet to the touch.
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.
