I think I have a good method to share for flushing components while they are removed from the system. I was not satisfied with the standard aerosol or liquid and air pressure. You get too much air blowing by the solids, never getting a good thorough push through the tube. I used a vacuum method. On one end, hooked up my Moeller 5 quart hand operated vacuum pump. Other end, I submerged in a bucket of solution. Vacuum away, I was able to keep a continuous flow going by keeping the bucket replenished. I was amazed how much oil and stuff came out. Emptied Moeller and did it again, until it was flowing clear. Then I vacuumed out as much of the solution and mist as possible, and then finished off with compressed air. Totally confident the tubes are now clear. For the condenser, Since the drier was removed, I simply put a piece of clear tubing in its place.

sounds like your method is the best. yes the oil will settle in every low spot and corner.

About to start this same project on my '72 GTS. My system appears completely original and never serviced. Components look pretty clean inside and the compressor turns freely and I can feel it is creating compression. The guys at Old Air recommended I replace the expansion valve, dryer, o-rings and convert to ester oil in the compressor for either R12 or 134. They also recommend cleaning all hoses and components with denatured alcohol. I'm thinking I should also buy a rebuilt compressor(?).    

What cleaning solution do you use? How does your Moeller connect to the A/C components/hoses, do you need special connectors? Do you vacuum in the reverse direction of flow? Have you recharged it yet and do you use R12 or 134?

Great post, thanks!

I used hot water and a little bit of evaporator concentrate cleaner. I think just the hot water would have been fine just to do the flush. Used the connectors that came with the Moeller. Direction didn't really matter to me, I just hooked up the rubber connectors whatever way seemed to give the tightest connection. I think after it flushed clear, that a final suction of alcohol would be a great idea to help evaporate moisture. I am doing a total conversion to 134, so new compressor, hoses, drier, valve...Haven't installed yet. Just finishing up assembly of engine.
