How Much R12 Does My 930 Hold?

[Quick930]

I had a bad A/C condenser and have a new one on order and wanted to find out how much R12 are system holds? I have a 30lb cylinder.

From Griffith.com Mr. Ice Project:

Optimally we want the lowest possible high side pressure with the lowest vent temp possible. Normally when charging the 911 with R12 you would observe the drier's site glass as an indication that the system has been "filled" with R12.

They started with 16 oz of R134A and worked up to 30, the pulled back to 26 oz. This is with three condensors [one in driver's R fender] yours would be less b/c only have two condensors.

I am sure the correct guesstimate is listed in the factory manuals. They are available online here somewhere ... search :)

Good luck.
