One of the tools needed is an information tool called the pressure chart.

Automotive a c pressure chart. This simple fix recharges the R-134a freon stop leaks gets your car AC cold again. FOR AUTO AIR CONDITIONING R134a SYSTEMS. At Sea level water boils at 212⁰ F R134a boils at 15⁰ F.

Automotive AC Pressure Chart for Air Conditioning Systems with R134a. Note that pressure gauge readings vary with ambient air temperature humidity and system design. The low-side should be near 30 PSI at 90 degrees Fahrenheit or less.

On a 90 degree day the LOW side reading should be about 70 psi or higher. R-134a System Pressure Chart. Automotive AC Diagnostic Checkout Procedures Please send comments corrections and additions to.

On a properly working system high-side pressure will be about twice the ambient temperature plus 50 PSI. At IDLE - Condenser inlet temp 170 to 180 Condenser Outlet temp 135 to 150 usually a 30 to 40 degree drop in temperature across the Condenser Evaporator Outlet temp 45 to 55 Compressor Suction temp 60 to 70 usually a 15 to 20 degree.
