Any ideas on how to remove a stubborn brass fitting that connects the AC evaporator core to the Accumulator/ Drier? I am trying to replace the AC accumulator while I replace my compressor, but I can't get the male fitting to budge at all. This is the fitting over the evaporator input line that connects and seals to the female port on the accumulator. The accumulator is located on the passenger side firewall with very little room to get my 12 in adjustable end wrench (crescent)over the fitting.
I've tried loosening what is binding the fitting by some light tapping on several of the sides with a hammer.
I've used penetrating oil.
I've used a 12 inch pipe over the wrench handle as a lever.
Each time I've torqued the fitting I've tried to hold the accumulator steady so I won't end up twisting, kinking and damaging the tubing going to the evaporator, but it's getting hard to use more force to break the connection between the accumulator and the fitting without risking damage to the evaporator tubing.
Any Suggestions? Would heating the fitting and accumlator connection area with a small propane torch possibly help loosen what is causing it to bind? Or would that cause more damage and melt an internal 'O' ring?
I would really like to avoid cutting the connection and then having to replace the evaporator too.
