I'm bypassing the AC in the sleeper in my 1992 T800, I am installing a new grilledenser, york compressor, drier and expansion valve. My question is how much r134a freon should I put in since deleting the sleeper part of the AC? It will be basically a day cab version now and how much oil should I put in the new compressor before I install it. It came shipped with 12oz that I emptied out but the APAIR guy said to put 2oz/lb of freon total but start with 2 oz in the side of the york compressor and then distribute the rest throughout the system but he said the daycab freon amount should only be about 2.5 lb total in it so that would only be 5oz of oil total. MHC Kenworth service said to put in 3.7 lb of freon so I'm not sure what I need to do.
