Exhaust Heat Shields

DESCRIPTION






The exhaust system heat shields are attached to the under boy of the vehicle. On vehicles equipped with All Wheel Dive (AWD), a heat shield is mounted to the catalytic converter.

OPERATION
Heat shields are needed to protect both the vehicle and the floor pan from the high temperatures developed near the catalytic converter and muffler.
Avoid application of rust prevention compounds or undercoating materials to exhaust system floor pan heat shields on cars so equipped. Light over spray near the edges is permitted. Application of coating will greatly reduce the efficiency of the heat shields resulting in excessive floor pan temperatures and objectionable fumes.
