Thread: Need help Finding A/C Leak

Hi guys, 2001 GT with 3.8, a/c quit last summer. Compressor wasn't engaging, so I added 2 cans of 134a around August and it blew cold for about 2 weeks and then quit again. Now the compressor won't kick on, so telling me that the refrigerant is leaking out and the low pressure switch is doing its job by keeping the compressor off. Also telling me that the leak can't be huge if it took 2 weeks for the pressure to drop low enough to kick out the low pressure switch, and that everything is the system is working as long as I can keep refrigerant in it.

Sooo...how do I start looking for the leak? Any known places where they "always" leak? I don't have that much experience with a/c repair so need some troubleshooting tips.

Well, you could refill the system and then spray some soapy water around all the connections/lines/etc and see if you get any bubbles.

Best bet would be to take it to a shop and have them dye test it I would think.

Ok thanks

Guys, see pic below. is this an a/c line? It runs from the radiator under and then somewhere.....it looks like it's leaking. Well I guess here's another way to ask the question: do GPs have power steering coolers? If not this is definitely an a/c line. Any what this called if I wanted to order one??

This is on the drivers side, radiator would be on your right in this pic, big thing on the left is the exhaust crossover.
