Ford E-450 bus AC conversion - Add how much?

Year: 2000
Make: Ford
Model: E-450 cutaway bus
Engine Size: 7.3L
Refrigerant Type: R134A

Hi all!

I have a 2000 E-450 cutaway bus (7.3L diesel) that originally had the AC condenser and fans mounted on the roof with no engine mounted condenser. I removed that system to make room for the RV conversion and now I'm working on restoring the AC system back to a "normal" van (front only) AC.

I've removed the old rear hoses and installed a new condenser in the engine compartment and also replaced the accumulator/dryer, the orifice tube and one of the low pressure hoses. The old system was holding pressure when I removed it and the old orifice tube was squeaky clean. The AC sticker inside the hood is for the old roof mounted system so I can't use those specs.

I'm getting ready to recharge the system so what I need to know is the amount of oil and refrigerant to add. Also, is it best to remove the compressor and drain/replace the old oil or can I just add new oil by opening the low pressure return hose and pouring in the new oil before vacuuming and recharging?

Thanx! Rick from Farmington

Never mind, I found the system capacities listing.

For anyone who's interested, my system needs 44 ozs of R134 refrigerant and 9 ozs of PAG 46 oil.
