Tools Required

J 36660-A Torque Angle Meter

1. Install the front cover gasket. The gasket is reusable and does not require sealer.

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.

2. Install the upper front cover bolts.

Tighten
Tighten the fasteners to 12 N·m (106 lb in).

3. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
4. Install the remaining front cover fasteners.

Tighten
Tighten the fasteners to 12 N·m (106 lb in).




5. Lubricate the front oil seal and the sealing surface of the crankshaft balancer with Chassis Grease GM P/N 1051344 or equivalent.
6. Install the crankshaft balancer. Refer to Crankshaft Balancer Replacement .
7. Install the right splash shield. Refer to Wheelhouse Splash Shield Replacement in Body Front End.
8. Install the right front wheel and tire assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
9. Lower the vehicle.



10. Install the engine mounting bracket adapter.

Notice: This bolt is designed to permanently stretch when tightened, and therefore MUST be replaced anytime it is removed. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.

Important: If you remove these bolts, replace with new bolts.

11. Install the engine mounting bracket adapter bolts.

Tighten
Use J 36660-A in order to tighten the bolts to 110 N·m (81 lb ft) + 90 degrees.

12. Lower the engine.
13. Install the engine mount assembly. Refer to Engine Mount Replacement .
14. Remove the J 28467-400 and the J 28467-360 .
15. Install the drive belt. Refer to Drive Belt Replacement .
