A/C pressure for 1993 Cad Seville R12

Bob B on Tue August 21, 2012 6:24 PM User is offline

Year: 1993
Make: Cadillac
Model: Seville STS
Engine Size: NS 4.6
Refrigerant Type: R12
Ambient Temp: 95-100 F

Can anyone advise the low& high side pressures for the above vehicle?

Thanks,

Because of the system configuration on this vehicle, you really want to charge weight. Location of the service ports makes pressure readings almost useless.

If like the DeVille, self diagnostics shows the hi and low side pressures in *C, but need a PT chart or a good memory to convert that into PSI. Really a CCOT system, at 85*F shoot for 28/220, but need special adapters with a right angle connector.
