    I misread your original post. Which hose are you replacing? I thought you said, condenser to accumulator. Accumulator to compressor (low side hose) is bit more challenging if it's the OEM type hose size. The DPI hoses would be very easy to fish through the frame space.

    Adding onto a recent and relevant thread...for those who have done so, what should be my time expectation for me to replace the AC compressor, the lines, & accumulator? Evap and condenser will be cleaned out, but will remain in place.

    I want to have it ready for the the Woodward Dream Cruise and that's only a month away.

    Thank you in advance.

    None of it is very hard. If you have a lift you could knock it out in a weekend easy. I'm using car jacks and am stuck with the last connection from the accumulator to the evaporator. Now having to resort to using a dremel to try and cut the accumulator off. If it wasn't for that one connection causing so much frustration I would have been done a month ago! Hopefully you don't run into anything like that!

    If you are replacing all the lines I found it was easier to use a handsaw and cut the old lines into smaller pieces to get them removed off the car.

    If you break the line going to the evaporator, add much more frustration and at the very least another full day to fix your AC.

    You should not have to replace the compressor unless it is making bad noises. If you are familiar with the job and things go well (everything comes apart easily, no contamination) it's about a 4 hour job figuring an hour for evacuation.

    OR of it's not working. I've seen plenty of bad compressors that are not noisy but need replacement. You gotta have gauges to make the determination.

    That is a bugger of connection to get wrenches on. The Evaporator nut is steel Female thread. I don't no how you are cutting the Accumulator Nut, but you must not damage the Evaporator Nut or tube. Replacing the Evaporator is big job. I've done it, and hope I never have to do it ever again.

    Before you resort to cutting, Try penetrating oil. You could Also Carefully try heating the large Hex on the Accumulator. Aluminum will expand easily.

    Mist have not been too bad. Total bill was 300 and that was replacing the accumulator as well as convert and charge it. That was several weeks ago and the AC has been doing fine ever since. I have always refrained from 134 but really I can't tell a difference in vent temps.

    Or if the compressor is leaking (not exactly rare), and you don't want to go through the chore of re-gasketing it.
