Well I can tell you the condenser is not in that great of shape. But until I can get one it'll have to do for now. The pressures drop quite a bit if I pour some water over the condenser. I haven't tried it since I installed the new drier so I'll see what the pressures look like tonight. Should I try to set the freon level by pouring water over the condenser or by letting it run free standing? If I have the right amount of freon in the system then it has to be on the evaporator or condenser side and possibly both. You figure 20 years of dirt and debri on both coils is going to have a negative effect.

I didn't flush the system.

The conversion was already done when I got the truck so I don't know if the expansion valve was changed or not.

The FSM only shows (1) way to measure the oil and that's by removing the compressor. I didn't want to go that far to be honest. I can say that I lost about a tsp full of oil when I was first trying to get the high side quick connect on. But I don't think it was enough to hurt anything unless it was low to begin with. I believe the FSM calls for 2.0 - 3.0 oz's.

I know a lot but this is not my area of expertise. I appreciate having someone to bounce thoughts off of and get input from. It helps a lot. <img src="/forums/images/graemlins/cheers.gif" alt="" />
