STANDARD VALUE

Diagnosis:

If cooling cycle is operating normally, the manifold gauge reading will be approx. 21 - 28 psi (1.5 - 2.0 kg/sq.cm) for the low pressure side and approx 206 - 213 psi (14.5 - 15 kg/sq.cm) 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.
