A friend who I maintain(and repair) a 98 Chevy Tahoe 2 door 4x4 needs working AC, he will be using his truck to transport dogs for a rescue organization he volunteers for - despite my urging to tell him get a truck or van for the day from Getaround(Uber's car sharing arm)/Zipcar/Enterprise and get reimbursed for it, he wants to get the AC working again and use his truck. Last year, I've tried to top it off with AC Pro(yea I know, bad for HVAC recovery machines and against my usual practice of nothing but oil and refrigerant in the AC system) and found out the system was tampered with a loose connection at the accumulator/drier and the compressor is shot. It makes a loud screeching noise so I'm assuming the compressor's gone bad. I plan on replacing the compressor, manifold hose set(cheap part, no rear AC on this model) and accumulator and trying to flush out the condenser and perhaps evaporator with mineral spirits or acetone to try to remove the sealer that AC Pro uses and any metal glitter trapped there. I've read the original Delphi compressor is a belly leaker(thanks JHZR2) and corrosion at the compressor halves will destroy the sealing surfaces. Amazon and eBay sell Chinese Denso and Sanden clones with a new accumulator, orifice tube and O-rings. Pick & Pull is having a sale this weekend and I can try to find a used OEM compressor for half off plus core charge. I'm trying to keep the price below $250 for parts, should I just get the new Chinese compressor and cross my fingers it will run for a year or try to find the OEM Delphi compressor that's in good shape?
