Chevy 1992 G20 Sportvan 350 A/C pressure and other questions

Hello all,

It's time to change the A/C and I would like to know the suggested GM A/C pressure quantity for the vehicle

I also appreciate it if you could please suggest me the most important accessories , aftermarket and performance parts websites for this vehicle

I currently live in Spain and it's quite difficult to find an on-line dealer who ship merchandise to Europe

Thank you in advance for your responses

Carlos

Welcome to AF.

AC low side should range 25-32 lbs.
High side will vary to outside temptures.
150 -250 is good high side readings.

Always check pressure at adle and at 2K rpm.

Google search for performance and other add on stuff.
