Exhaust Heat Shield Replacement Front

1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

Notice: To prevent internal damage to the flexible coupling of the catalytic converter assembly, the converter must be supported. The vertical movement at the rear of the catalytic converter assembly must not exceed 6 degrees up or down.

2. Suitably support the exhaust system.
3. Remove the three way catalytic converter for access. Refer to Catalytic Converter Replacement .
4. Remove the exhaust pipe front heat shield bolts.
5. Remove the exhaust pipe front heat shield.

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.

1. Install the exhaust pipe front heat shield with the bolts:

Tighten
Tighten the exhaust pipe front heat shield bolts to 7.5 N·m (66.38 lb in).

2. Install the three way catalytic converter. Refer to Catalytic Converter Replacement .
3. Lower the vehicle.
4. Inspect the exhaust system for leaks and underbody contact.
