Component Tests and General Diagnostics

Exhaust Heat Shields
1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Maintenance/Service and Repair.
2. Inspect the exhaust system for loose or missing heat shields or foreign material trapped between the heat shields and the exhaust system components.
3. If any heat shields are loose, install worm gear clamps.
^ Use one of these clamps: F0TZ-5A231-A or W705949-S300.
^ Tighten to 7 Nm (62 inch lbs.).
^ Trim off the excess ear of the worm clamp.
4. If the heat shields are missing, install new heat shields or exhaust system components as necessary.
5. If a rattle, noise or buzz condition persists, install a new heat shield.
6. Lower the vehicle.
