Refrigerant Pressure Inspection

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)
