Muffler: Service and Repair
REMOVALAll original equipment exhaust systems are manufactured with the exhaust tailpipe welded to the muffler. Service replacement mufflers and exhaust tailpipes are either clamped together or welded together.
WARNING: IF TORCHES ARE USED WHEN WORKING ON THE EXHAUST SYSTEM, DO NOT ALLOW THE FLAME NEAR THE FUEL LINE.
CAUTION: When servicing exhaust system components, disconnect the oxygen sensor connector. Allowing the exhaust system to hang by the oxygen sensor harness will damage the wiring and/or sensor.
1. Raise and support the vehicle.
2. Disconnect front tailpipe hanger from the insulator.
3. Remove the mounting nuts from the muffler to catalytic converter flange.
4. Remove the clamp retaining the tailpipe to the rear tailpipe hanger.
5. Remove the muffler and tailpipe assembly from the vehicle.
INSTALLATION
All original equipment exhaust systems are manufactured with the exhaust tailpipe welded to the muffler. Service replacement mufflers and exhaust tailpipes are either clamped together or welded together.
WARNING: IF TORCHES ARE USED WHEN WORKING ON THE EXHAUST SYSTEM, DO NOT ALLOW THE FLAME NEAR THE FUEL LINE.
CAUTION: When servicing exhaust system components, disconnect the oxygen sensor connector. Allowing the exhaust system to hang by the oxygen sensor harness will damage the wiring and/or sensor.
1. Position muffler and tailpipe assembly into vehicle.
2. Install clamp retaining tailpipe to the rear tailpipe hanger. DO NOT tighten clamp at this time.
3. Install mounting nuts onto the muffler to catalytic converter flange studs. DO NOT tighten nuts at this time.
4. Make sure the exhaust system is in proper alignment. There should be at least 25 mm (1 inch) clearance between the exhaust components and any surrounding components.
5. Tighten muffler to catalytic converter flange mounting nuts to 28.5 Nm (21 ft. lbs.).
6. Tighten tailpipe clamp to 48 Nm (35 ft. lbs.).
