I got the leak on the condenser fixed and it is ready to recharge as soon as engine repair is complete. I have Haynes and CHilton manuals but neither gives info on specific amounts for ac recharge, or normal operating pressures. I looked all over for a sticker with this info (on original r-12 charge) but didn't find one. I got a case of DuraCool to try in it. I COULD just charge blindly until it is cooling, but would rather know what system pressures are supposed to be with the (equivalent) DuraCool charge (you use a lot less by weight), so I know when to stop. This refrigerant is supposed to run with a lower high side pressure.
