How do I know if my heat shield is loose?
If the heat shield becomes loose, damaged or broken, perhaps due to loose hardware or damage from rust, it will cause the heat shield to vibrate and produce a rattling sound. The rattling will be most prominent at low engine speeds, and may change in pitch or tone according to engine speed.

How does a heat shield work on a car?
A majority of that heat is released by the exhaust manifold, the metal pipe through which the exhaust gases exit the engine. In order to prevent this extreme heat from damaging the components under the hood, a heat shield is used to help manage and contain the high temperatures.
