PERFORMANCE TEST DIAGNOSIS USING MANIFOLD GAUGE

STANDARD VALUE
If cooling cycle is operating normally, the manifold gauge reading will be approx. 21-28psi (1.5-2.0kg/cm2) for the low pressure side and approx. 206-213psi (14.5-15kg/cm2) 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.
