95 A6q AC Questions...

[toomanyaudis at aol.com]

Does anyone know what the operating pressures of a 95 A6q AC system should be?

I'm trying to determine if I overcharged or undercharged the system after I replaced a leaking hose. System cools, but not particularly cold.? My 88 80q cools much, much better.

Receiver Drier and Expansion valve were replaced with hose, system vacuumed out overnight, recharged through high pressure port and refrigerant amounts estimated from content on cans.? Unfortunately, there's no low pressure port on these cars.

here are the specs:

Ambient Temp: 82 Degrees Farenheit.

Pressure in System Resting: 105 PSI

Pressure with Compressor Turning: 210 (idle) to 250 psi, depending on engine speed.

Of course, if I had a low pressure port, I could do a better job of diagnosing the problem.

Any input?

Thanks,

Tom
