Stop-Leak in air conditioner?

Question

I have a '98 GMC Jimmy and the a/c has gone out in it. When I took it in to be seviced, the technician said that I had a slow leak of the freeon (sp). I don't know if the leak was in the comprssor or a hose. I was just wondering if stop leak could maybe stop the leak. They recharged it, but after a couple of months it stopped cooling again. A "friend" said that he used stop leak in his and has been running cold ever since. Was he just pulling my leg beacuse I am female or is there something to this?

Answer 1

I've had some luck with it some of the time and then again, it hasn't done any good.

The best way to fix it, is to get the leak repaired. I know that it isn't the cheapest but it is the best way to do it. Then you are done with it and next year you know it will still be working, where your friend will have to guess and most likely it won't work.

If it is only a a leaking seal in one of the hose connections then it shouldn't cost too much to get it fixed.

good luck.

Answer 2

Well if its a seal leak/very small hose leak etc ...charging it with freon with system safe stop leak in it may cure the problem but alot of times this is a band aid and it wil leak again...you could put the fron with the uv dye in it, fill it and after a while use a blacklight and look at all the hoses etc.// Im willing to bet ya the leak is in the condenser which is in front of the radiator , usually stones from the road get flung at this and put pinholes in them...have somebody look and see if there are any oily spots on it, or on you hoses etc...since fron contains oil sometimes you will find the source of the leak to make a decision on whee to go with the problem next

Answer 3

He is pulling your leg. The freon in the AC unit is not chemically compatible with 'Stop-Leak' which is used in automobile engine coolant systems. When you next have your A/C serviced, ask about the freon with a dye in it so the leak can be seen easier.
