AC Stop leak

[landtank]

I don't remember reading anything on this. I have a leak in my condensor. While up at the FJ Cruiser gathering in NH I talked with the mechanic at that shop and he mentioned he used this stuff with great success.

I get nervous about any stop leak stuff since the 60's with clogged heater cores.

I've heard from a farm & auto mechanic that it can successfully stop small leaks as long as they're not in the compressor itself. I have not used it myself.

Some professional AC techs will use the stop leak. Other professional AC techs believe it is a bad move that ultimately results in more work for them.

I put some in my '91 about five years ago; haven't had any problems and it gets used a LOT in the summers. I'm not saying it's the right way to go; just that I did it and it's working. Don't know where the leak was...

Just bought some for my 84 Cressida; still debating whether to put it in...

the truck has 200k on it and I know where the leak is, it's the condensor which is over 200.00. Everything that I've read says that while it is a stop leak it is also a lubricant of some sort. And if your leak is plugged the rest stays in there as a safe guard for when the next leak appears.

I think I'll just give it a try.

I just had my truck a/c serviced. Basically what the others said. Stop leak only works for small leaks, but it won't repair a damaged system. Apparently, some of the shops don't like it because they aren't equipped to deal with evacuation of the system (it can gum up their equipment). Overall, I think the advantages outweigh the disadvantages, so I opted to have it put in my truck.
