Believe it or not, there is a STOP-LEAK for auto A/C...It was developed by NASA for their spacecraft...There are two types, one sells for 300 bucks a bottle and the other for $50...I had the $50 put in mine with a leak in the evaporator unit and a leak in the compresser....Works great and saved me almost a $1000....Don't let these mechanics tell you otherwise....IT WORKS.....

Give us a name. I could definitely use some of that for my truck.

While this worked for me, it will not work on major big leaks...The leaks have to be small and slow...
The name is TLC 2121, (TLC is the company's name) and is made in Sunrise,Fl., which I believe is in the Miami area...

Well, its been almost another year, and my AC is still working super...That stuff really do work.....
