Heat Shield: Description and Operation

Sound insulators and shields protect the vehicle from exhaust system heat and should be inspected at regular intervals to ensure they are not dented or out of position. If a sound insulator and shield is damaged or shows evidence of deterioration, it should be replaced. The sound insulators and shields for the muffler, muffler pipe, resonator, and TWC pipe are replaceable separately.

Sound insulators and shields that are attached to the TWC are not repaired other than to replace missing or damaged attaching parts such as clamps or screws, and to remove debris that may collect in the shield area.
