Manifold Gauge Test
PERFORMANCE TEST DIAGNOSIS USING MANIFOLD GAUGESTANDARD VALUE
If cooling cycle is operating normally, the manifold gauge reading will be approx. 21-28psi (1.5-2.0 kg/sq.cm) for the low pressure side and approx. 206-213psi (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.
