My 1987 Cutlass Supreme is in pretty good shape - it runs well, gets decent gas mileage, ect... The problem is that the inside of my car always has a faint smell of antifreeze, and I have no idea what it's from. I've cleaned the inside, used air fresheners, but my final thought is that the smell is coming in through the air vents, even when the a/c is off. Does anyone know of any specific places in the ventilation system (or other parts) that I should be checking for antifreeze leaks, or anything that may be causing this odor? Thanks, Mike.
