You only need to change the condenser if the tibds are damaged or the compressor has puked metal shavings. You always have to change the accumulator or drier when you change compressors.
Watch a few YouTube videos to see what is involved.
Hey Stamp, you ever worked on many mini bus systems like Turtle Top or other shuttle style cutaway van chassis bus ac add ons? Trans Air I think is the most common.
I used to have an E Super Duty with one and getting ready to replace compressor on another add on RV/Bus style system.
Has Large rectangular condenser underneath vehicle mounted going down side and evap similar size evap inside with expansion valve and sensing coil I'm pretty sure (will look tomorrow). I remember calling Turtle Top back then and talking to a very helpful tech there about proper charging pressures.
I recall I was seeing higher low side than I expected. He told me they usually charge with 4-6lbs...BIG variance to me.
I has good to even low high side but low side was 50+. I think he told me or I read somewhere that even up to 60 is normal for these.
I got to the point to where I would put an accurate digital thermometer in the vents and charge to coldest temp without it increasing as long as high side stayed respectable.
Any experience or advice appreciated.
This compressor was cooling some but loud and clicking/tapping. It smoked the clutch so it might be locked up now. I am debating to flush or not. I don't like flushing products....I have always been a denatured or isopropyl alcohol flusher on the few I have flushed and I think only condensers anyway.
I don't think this system even has a receiver/drier. It may have a small filter/drier in the high side closer to compressor. I will have to look.
Any crud or ring pieces from compressor (don't know if it has metal or teflon etc) should be in the condenser or caught at the screen on the expansion valve so I might unhook and look there and flush or blow condenser backwards.
I have never liked putting an air hose to ac component but I'm not going to go buy nitrogen just for this. I have CO2/Argon but that is expensive!!! Lol I guess I could spare a few strong shots. Not sure how much better than air CO2/Argon would be but would have to be better than moist shop air in this humidity.
Back to sealer. I know the stuff you are talking about that clogged machine. Prob the interdynamics stuff. I used it once and it was a gray rubbery mess and clogged an LHS expansion valve instantly. Total waste of 19.99 but I did clean out expansion valve and it flowed afterwards through all other parts.
I have never had the Red Angel clog anything but all sealers are risky and best to find and fix the problem.
