Ac lines stuck on compressor

Any suggestions on how to get the ac lines unstuck from the compressor? The compressor is currently soaking in pb blaster and sitting on the front sway bar with the lines frozen to the threaded stud.

I've replaced a dozen compressors in the past month and mine has to be the one to give me problems.

I'm done with not having ac so I installed a new condensor, receiver/drier, orifice tube, seals, and as soon as the compressor is on, I can hook it up to the machine and get it going for once.

There is a product called "freeze off" that may loosen the parts. My brother used it on a stuck O2 sensor, and it became almost finger tight.

Almost a whole can of "freeze off" and all I've got is the smell of pine sol all over.

If freeze off did not work, I am at a loss. There are seals under the clamping plate, but I do not know if the aluminum will withstand being pried off. The aluminum is mostly dead soft.


You may have to hit the local junk yard for a replacement. They are usually easy to remove, and the yards do not charge a whole lot for them. Most of the time they pop right off, especially if someone left the refrigerant in the system.

There are a few here, and a couple have the hose intact.

Send a message via AIM to Blue Wail
Id replace both the lines and compressor.
After 16 years, neither is probably any good
especially with the problem you're having.

Even with shipping, the RA part is probably just as cheap as the junk yard part with shipping, and it is new.

Yeah I priced the line out last night and ordered from Rock auto. It would have been $17 at a junk yard for me to pull it, plus pay $2 entrance fee.

I did manage to get the line off after pulling the compressor with lines attached.

Does anyone know offhand where the orifice tube is located so I can knock that out when I get home.

It should be in the hard line between the condenser and the evaporator.
