I just picked up a 96 Civic and the AC doesnt work. The car was in a front end accident and I dont know what was damaged and what was not or who even repaired it. I was going to replace all the O rings where the car was affected by the wreck. I went to a handful of auto parts stores and nobody had any idea if I needed special seals for the AC lines or not. Also I was wondering if I could pressure test instead of doing a vac. test cause I dont have access to a vac. tester but I do have access to a compressor. Any help or inisight links ect. would be greatly appriciated. Thanks!

Yes you need O-rings rated for R12/R134a. Find a local A/C shop for help. They have die they can inject to spot leaks.

 

Ya Ive been doing some reading and I guess you cant pressurize the system with air because there is water in the air and you DONT want water in the system. I think that they guy who had the car before me just threw it togeathor and didnt use the right rings. Thanks for the help!

Be sure to replace your reciever/drier then.

Get a water seperator to put on the air line then you will be good to go. You should have one anyway if you use your air tools with it. You should be able to get the rings at any local auto shop and you can test it yourself. The 134 with dye and just about anything you will need for it you can get at wal-mart, autozone, pepboys, ect. To fill it you will have to pull a vaccum on it.

 

I was thinking that I could just prolly test it and fill it myself with the dye, but I replaced all the underhood seals today and plan on having it vac. tested shortly here hopefully this weekend and see if it decides to hold vac. If it does then Im just going to get a recharge kit and go from there. If not Ill prolly just get some of that stuff with the dye and go that route. The only thing I dont like about that idea is that basically you fill your system and have it all leak out, find leak repair whatever needs to be repaired then go and buy MORE freon. AND, if there is another leak in the system, there goes the freon you filled the second time. Seems to me that its a better idea to find the leak(s) before you fill the system so you dont waste $ on freon. How do I know if I need oil for the compresor (green sitcky stuff correct?) ? Ive had some come out of the lines when working on em today...
