my heat shield fell off my 1991 caprice classic. it‘s located between the gas tank and the rear exhaust. the mechanic told me it does not have to be replaced. is this true?
Well. drive your car around for a while without it and see. if it blows up, then I guess you needed it.
If you see smoke and fire you should fix it.
Personally I think it should be replaced. They put it on there for a reason. To protect from heat from the exhaust and as sort of a skid plate for the gas tank. I'm guessing its a plastic tank but I don't know for sure. Without it it would be easier to puncture.
