Drives really slow
Okay... so everything on my AC system has been replaced including the lines. Everything has been completely flushed and dried except the compressor and the accumulator obviously. I filled the system with the prescribed amount of oil which in my case was 10 oz of pag 46. Compressor came with 3 in it, so I added 7.
So last night after having pulled vacuum for weeks and purged with nitrogen a couple times I go to charge it up. I'm using Duracool, so I'm sure many people will say that is the issue, but I don't believe so... From everything I've read it behaves almost exactly like R134A when filling it up except you put in less and it runs at a lower overall pressure because of that.
Anyway, I start putting in the Duracool with the compressor running, my low side pressure starts around 30 psi with the first can, which seemed odd, should be lower I would think. Then after putting in 4 cans the low side pressure doesn't drop below 60 PSIG, and the temp at the evaps doesn't drop at all. The static pressure with the compressor off is 70 PSIG, which is okay with the Duracool. The low side pressure should be dropping more than 10 PSI. The high side is getting around 110-120 PSIG. ***...
Only thing I can figure is the compressor is bad or the orifice tube and/or expansion valve is somehow letting refrigerant by without a restriction. I double and tripled checked the orifice tube and it seemed sealed. It is the variable orifice tube also. The expansion valve on the rear evaporator is a brand new OEM ford.
Does anyone have any good ideas on how to diagnose or troubleshoot this thing without letting out all my refrigerant? Any help is appreciated!! This would be the second brand new reman part I've had fail immediately on this rebuld. First was the redhead steering gear.
