SERVICE PROCEDURE

WARNING:

The exhaust system may be hot. Allow to cool down before inspection/repairs.

NOTE:

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.

5. Secure the band clamp with the hex bolt located on the side (or on top, if needed). See Figure 1 above for example.

WARNING:

Do NOT install the hex bolt on the bottom of the exhaust tube.

^ 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

2).

WARNING:

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