From my own vehicles the pressures look fine. Are those pressures done at full operating temp? Also what's your idle pressure? You should try to find what the factory specs say it should be.

Idle pressure is 30 psi 900 rpm. This car has a clutch fan and an electric fan. I tried to test the electric fan by turning on the a/c and it didn't come on. There was no power at the plug. Is the electric fan supposed be on when the a/c is on, on this model?
