Heat Shield: Description and Operation

Heat shields are needed to protect both the car and the environment from the high temperatures developed in the vicinity of the catalytic converters and exhaust manifolds. Additional thermal insulation is used in the sill panels and above the rear muffler.

CAUTION: Avoid application of rust prevention compounds or undercoating materials to exhaust system floor pan heat shields on cars if 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.
