Refrigerant Pressure Inspection

Checking refrigerant pressure
1. Connect manifold gauge set.
2. Operate engine at 2,000 rpm and set air conditioner to maximum cooling.




3. Measure low- and high-pressure sides.

Normal pressure
Low-pressure side: 20 - 41 psi (137 - 285 kPa, 1.40 - 2.91 kg-sq cm)

High-pressure side: 185 - 263 psi (1,275 - 1,815 kPa, 13.0 - 18.5 kg-sq cm)
