How much A/C oil?

[rollfj]

I'm replacing the hoses and accumulator/dryer on my trucks A/C (Factory Air, converted to R-134).

One of the old hoses developed a really bad leak and the system has completely vented all the refrigerant, I now have a huge oily area on my inner fender by the leak (close to where the hose connects to the condenser on the driver's side).

How much oil should I add to the system when I re-assemble it? I have all the tools and the vacuum pump, I just don't have any data on this system?

Thanks,

AFTER flushing the system, My book says 7.00 oz. then there is an *

*On models with "authorized Modification" decal ( on radiator support near VECI label), add only the specified amount of refrigerant oil.On all models without this decal (except the following exceptions), add the specified amount plus an additional 2.00 oz. On 1993 through 1996 Bronco and F-Series Pick-ups without a decal, add the specified amount plus an additional 4.00 oz. If there is no decal on 1994.......


BASED on that I would think either 7.00 oz or 11.00 oz depending on the sticker. Best isto put 1/2 in the compressor and 1/2 in the drier/reciever.

Operating pressures:
LOW side 28-45

HIGH side 128-230

I would try to get the low side to about 35 and the high side to about 200.

Your welcome. When I looked this morning ( had to replace my vacum pump) My label says 7.00 oz. of oil but mine is allready 134a from the factory.
