2001 Jeep Cherokee Question: will stop leak damage a/c

 

Question

Last year my a/c quit working and the mechanic used stop leak and it worked for a year, then the mechanic I learned did it again this summer, it stopped and I added freon, it worked for a while then stopped and stop leak was used again, will it clog up my system? The a/c has blown cold for several days but the pressure tht I told at home shows it just around 25-30? Also I was told it could be an evaporator could the stop leak have damaged a compressor, it still clicks on and off? Are there any signs it if damages a condensor, compressor, or evaporator, like it won't keep a charge for long, or won't recharge past a certain psi depsite the amount added? Tahnks

    The last part of your question is a bit hard to understand so I hope this answer helps. I do not think that adding stop leak three time over the last year or so would damage any of your A/C system components. It is a bit excessive however. It may be time for the A/C system in your 2001 Jeep Cherokee to be completely diagnosed by an A/C professional. If there is still a leak it must be found and repaired - it seems that the stop leak did not work to seal your A/C leak. Once the leak is found and repaired the system can be fully charged and inspected for other issues.

    I don't like using stop leak additives unless it is an emergency or you really aren't interested in putting money into the vehicle.
    You system still has a leak, it will need to be located and repaired. It can be a hose, evaporator, condenser, basically can be from anywhere. What the repair shop should do is add fluorescent dye into the system to help locate the leak. As far as all that stop leak damaging the compressor, I don't have any experience with it to know, but my feeling is that it can't be good.
    Either was, focus on finding and fixing the leak, recharge the system and see how the compressor is working.
    Good luck!

    STOP LEAK WILL NEVER DAMAGE YOUR A/C. IF THERE IS A LEAK IN THE SYSTEM AND THE STOP LEAK CANNOT PLUG IT, THE LEAK SHOULD BE LOCATED AND FIXED. THE FLOURESCENCE DIE WILL ALWAYS HELP TO DETECT THE LEAK.
