The AC in my 94 940 is working fine after adding a little more R-134a to deal with the Texas heat. But after reading the forums, I became concerned about the charge amount in the system. Outside of evacuating the system completely and adding the required 950 grams, is there pressure information available which would allow me to be more confident in the system charge?

The link in the FAQs to AirCondition.Com only provides vapor pressures for various refrigerants at ambient temperatures, not suction and discharge pressures of an operating system at various outside temperatues. There are scattered references to suction/discharge pressures at particular conditions (e.g. 85F outside temperature), but not a comprehensive chart like I have seen and used with other vehicles.

Thanks in advance!
