Finally found and repaired the A/C leak in my 01 XKR. Sensors and dyes nor stop leak did no good. I was about to remove the evaporator (major job) as I would get a squeal in the area of the firewall port. Decided to pull a vacuum on it first. In setting up and adapting to do so the hoses had to be forced out of the way. Vacuum held as did a test on the rest of the system. Another recharge. Wouldn't hold but a puddle of dye/ stopleak appeared on the floor. Suction hose crossing at rear of engine had a burn spot where it was up against the EGR pipe. Although the pipe is pretty well protected I believe the hose was routed on the wrong side of the pseudo transmission filler tube forcing it against the EGR Tube. I attempted to remove the hose assembly for repair I found that no amount of parts removal will allow it to be removed, I can see no way other than engine removal. I had a lot of stuff off the rear of the engine and could get access to cut the damaged area of the 5/8 ID rubber hose, it is just low pressure. Repaired by splicing in a 3/8 brass pipe nipple and high pressure clamps. Nipple has to be long enough to retain critical length of the hose. I slept well last night and will sleep even better tonight as the A/C is still working. Good thing I have lots of tools and patience as nothing on these cars is easily accesable.

 

It is amazing how such simple repairs often turn into lengthy affairs.

Congrats on the repair. Glad you got it fixed.
