Angry A/C Leak.. Possible O-Ring replacement?

Hey guys I had my A/C recharged and it leaked out. I am guessing its a O-Ring that is bad so I was wondering if any one run into this problem or know if there are any other seals that could/should be replaced. Thanks!

There could be numerous possibilities. I would add a cheap can of freon with dye and let it run through the system. Then get those ugly yellow glasses and check for leaks with a black light. If you take it to a shop, they will pull a vaccum test on it and try it that way.

The leak was coming from the front of the compressor it looked to be the line but I wasnt using the dye so I could not get close to it =/

Bighead222^ where did you get the O rings for the A/C?

Default ES300 A/C O-Ring Sizes

Hi,

I saw your post on replacing O-Rings in your ES300 A/C system. I measured one for the Condenser manifold and it measured 7/16 ID, 1/16 cross section but when I replaced it with a new HNBR they do not seal properly. Can anyone help identify the proper o-rings for the condenser and compressor lines?

Thanks. Carey
