  • Common Questions


    The whole dash has to come out in my 2005 Prius, so it costs $1614 to fix it. Will this stuff work on evaporators?


    I can only tell you that it worked for me in my 2008 Toyota Tundra, while my friend tried it in his wife's jeep.


    Is there a way to remove the air from the hose before putting it in?


    If you have leaks and you wouldn't be using this if you didn't, it won't help you.


    Is it possible to use the whole can?


    I used the whole can to fix A/C leaks on a 1997 Saturn and a 2004 Toyota Highlander.


    Is this the god for a nissan versa evaporator leak? How long does it last?


    It depends on the size of the leak.


    Will this not cause harm to shop equipment if I go for a evaporator replacement or gunk up the a/c system?


    It works for small leaks, but my valve core became the problem, so I would use it again in the future.
