System Diagnosis
Normally Functioning A/C System
Gauge Readings:
Low Side Gauge -
Normal.
High Side Gauge -
Normal.
Other symptoms:
Sight Glass -
Clear.
Discharge Air -
Cold.
Normal gauge readings will depend on system components
and ambient conditions, make sure that the valves are closed
and the readings are stable and that the system has a full
charge.
The pressures on the manifold at 25 °C with the engine at
1500 RPM, the blower on maximum and the thermostat set to
maximum, should be approximately:
Typically, the high pressure is 6 - 8 times the low pressure.
LOW SIDE - 2.0 bar (2.0 kgf/cm

)
HIGH SIDE - 14.8 bar (15.1 kgf/cm
