Switching to new compressor
I am fixing to do a conversion to a serpentine belt set up on my truck within the next three weeks. As some of you remember I just rebuilt my A/C last year for use with R134a and it has been working perfectly, thanks to everyone who helped me through the process 
. With the serpentine conversion I'm going to be switching from my York compressor to a newer style compressor (FS10 I believe). When I did the work last year I put 10 oz of Ester 100 in the York compressor crankcase. I know that oil gets circulated through the system. My question is what should I do when I install the newer compressor? How much oil should I add to it? Should I just use one of the cans that says "oil charge"? Or should I flush out the system and start with a new amount of oil?
Thanks,

Personally I would stick with your York compressor & forget the serpentine belt idea. But your going to have to break open the system wish means pumping the system down anyway so go with manufactures specs for oil. If your going to open the system & install a compressor most manufactures won't warranty their compressors unless you change the filter drier.

If you can,,,, drain the oil out of the york once you remove it and measure it.
You can add the difference for what the FS10 requires.
The evaporator and Condenser etc. are similar enough for the two systems to guesstimate the oil volume.
If you get 8 oz out, the FS10 takes 9 oz so you know that 7 oz would be the right amount.
10-8=2
9-2=7

Cool, thanks.
And Craig, I am changing the drier too. I'm not worried about having to pull the vacuum on it, because I bought a 2.5 CFM vacuum pump from Harbor Freight.
I'm doing the Taurus/Mark VII/T-bird (which ever one of those I can find) electric fan swap when I do this also. I already did the 130 amp 3G alternator upgrade.
I'm going to the JY Saturday to pull stuff.
