Muffler: Service and Repair
Exhaust Muffler Replacement
Removal Procedure
Important: The originally equipped, welded exhaust extension pipe can be cut and reused when installing a service muffler, if the extension pipe is in acceptable condition.
1. Raise and support the vehicle.
2. Support the exhaust muffler.
3. Cut the exhaust extension pipe just forward of the weld at the front of the exhaust muffler.
4. Release the muffler insulator from the underbody hanger and remove the exhaust muffler.
5. Deburr the extension pipe end as necessary.
Installation Procedure
1. Install the service muffler to the vehicle.
2. Slide the muffler inlet pipe over the extension pipe, then install the muffler insulator to the underbody hanger.
3. Install a service muffler clamp to the muffler inlet pipe. Position the clamp approximately 19 mm (� in), from the edge of the muffler inlet, with the clamp nuts oriented away from the evaporative emission (EVAP) canister.
4. Align the muffler and tailpipe to the vehicle underbody and rear bumper fascia.
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.
5. While maintaining muffler positioning, tighten the exhaust clamp nuts.
Tighten
Tighten the nuts to 45 Nm (33 lb ft).
6. Lower the vehicle.
