I am working on a GM air conditioner with a delco compressor. My suction line was leaking, and the compressor was going out. I decided to replace the other 2 hoses, condenser, and accumulator at the same time. ( everything but evaporator) I have all the old parts removed. Before I install everything I was wondering if I should flush the evaporator - it would be a major task to remove it from the hvac box. If I flush it in vehicle, do I need to worry about getting all the solvent removed when I blow it out with just my air compressor? I removed the orifice tube and it only had a little bit of residue around the bottom (largest) if the 5 screen sections, near the o-ring seal at the base.
My system takes 8.7 oz of oil ( 2.7 for compressor, 4 for accumulator, 1 for evaporator, 1 for condenser ). As I understand if you are doing individual component replacement, to just add the the proper amount to that component. In my case, should I add all of the needed oil to either the accumulator or compressor?
I plan to take it to a shop to get it evacuated/charged.
Any tips would be greatly appreciated.
