92 Cadillac Brougham

I believe I have a leak in my heater core (5.0L engine). A few months ago I noticed water in my floorboard occasionally. Then my defroster and a/c vents began putting out a sorta fog that smelled like antifreeze whenever I tried to use heat. With cooler temperatures here, whenever I park the car and come back to it, there is a film of moisture on the inside of the windshield. There seems to be a small leak of antifreeze just rear of the passenger front wheelwell. I really dont know where the heater core is located on this vehicle. I spoke with a garage about this problem and they suggested it was the heater core and quoted me a price of $200-$250 to replace it. Local parts store has this heater core in stock for $21.88 and I understand it would take a professional 2 hours to replace it. My question is, instead of replacing it, can I use a radiator additive like Bars Leak that claims it stops leaks in radiators, heater cores, and lubes the water pump? Just need a little advice from someone that knows more about this stuff than I do. Thanks for any help

Bottom line: You will have to replace the unit.

If its leaking that bad no stop leak is going to help you. Sorry! It is going to have to be replaced.
Did the diagram I sent you not help?
