Re: Vintage Air SureFit Condenser Kit 21567, for 1967-72 C10 and C20 Chevy & GMC Truc
Low side sounds really low. I would expect 45-55 or so. Was that at idle or a higher RPM, and did you have a big-a$$ box fan blowing at the condenser?
My only A/C experiences have been with complete V/A systems, and just today a 99 Chevy pickup. At around 85 deg ambient at 2,000 RPM we got it blowing 45 at the center vent, and, as I recall, pressures were 45-55psi and 150-160psi.
I assume you pulled a vacuum on the system before charging, right?
