Exhaust system heat shields protect adjacent components from being damaged by high temperature.
During service procedures, care should be taken to assure that heat shields are properly reinstalled. As an example, the new 1988 Quad-4 LD2 engine has a large heat shield at the rear of the engine. Even a short test drive without this shield installed may result in heat damage to the power steering gear boots.
