HELP, AC oil amount
I am working on my wife's 2006 Expedition limited with rear air (AC charge of 58 oz). The AC wasn't working so I checked it and it was very low on charge. I figured it was leaking so I added some 134a with dye. In one day it was very low again (like almost no charge). There was dye and oil all over the pump. I figure it is leaking out of a seal on the shaft (I could be wrong about that though, either way the pump is shot).
I remove the pump and got about 1 oz of oil out of it. I also drained the accumulator and got just a few drops out. I have a feeling most of the oil leaked out with the 134 because it was leaking so bad.
The new pump came with 150 ml (5 oz) of oil in it. I am now installing it with the oil in it.
How much oil should I add/ remove?
Thanks.

Only way to know for certain is to completely flush the system and refill it using the measures in the service manual. Anything other than that is pretty much a guess.
Total system oil capacity for your configuration is 14 oz.

Thanks for the reply. That is what I pretty much thought. I put 3 more oz of oil in figuring that about 1/2 would still be traped in the system. Just filled it with 134a and it is now cooling well again. I think it is slightly under charged, pressures are a little low for 70 F. Although the compressor isn't cycling off from low pressure on the low side. I would rather have it slightly under. I will have to wait to see if the wife complains.
thanks again for the response.
