If cooling cycle is operating normally, the manifold gauge reading will be approx. 1.5 - 2.0 kg/sq.cm (21 - 28 psi) for the low pressure side and approx. 14.5 - 15 kg/sq.cm (206 - 213 psi) for the high pressure side. Inlet temperature should be 30 - 35 °C (80 - 95 °F), with the engine at 2,000 rpm, maximum cooling selected, and the blower on highest level.
