Exhaust system parts do not need to be removed for this inspection/repair.

1. Raise the vehicle on a hoist.

2. Inspect the heat shields on the front exhaust tube for the following:

^ Heat shield contact with the exhaust tube.

^ Separated / missing band clamp(s).

^ Weld separation(s).

3. If a heat shield is found contacting the exhaust tube, pry it away to allow a minimum 1 mm (.040 inch) space.

^ Road test the vehicle to verify the repair.

4. If a weld or band clamp is separated, or the band clamp is missing, install new band clamps as needed.

^ For band clamp(s) location, refer to the pictures below that applies to your vehicle.

^ Band clamp hex bolt torque: 4.0 - 5.5 Nm (0.4 - 0.56 Kg-m, 2.9 - 4.0 ft-lb)

6. After securing the band clamp, cut off the clamp's excess at the end.

^ Wrap the end of the band clamp over the hex bolt, and then cut off the excess band clamp within 5 mm (0.2 inches) past the hex bolt (see Figure

WARNING:

Be careful of sharp edges after cutting off the excess band clamp.
