When to Use a Muffler Heat Shield | Roberts Automotive and Industrial Parts Manufacturing Corporation

A muffler radiates heat due to the exhaust gases of internal combustion in the engine. This heat can cause extreme injury not only to the engine, but also to other crucial car parts. And because a damaged car can lead to serious harm to the driver, passengers, and pedestrians, using a heat shield is a primary safety requirement.

Heat shields are placed between the muffler and the fuel tank to protect the fuel tank from the heat coming out of the exhaust pipes.  Though especially designed to continuously withstand high temperatures, heat shields wear out after a period of time, which establishes a need for a replacement.  Muffler heat shields should be used during long distance driving because the exhaust system of a car increasingly generates heat for as long as a car is running.

The mufflers of today are either reflective or absorptive. Reflective mufflers run generally hotter than the absorptive ones, so heat shields are an absolute must if your car has this kind of muffler.  More than half of today’s mufflers are absorptive types, and it’s a good thing that the reflective mufflers that abound the market are already equipped with heat shields.
