Compressor Discharge (High) Pressure
WARNING: This page is about a different car, the 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
In ambient temperatures is 100-110°F (38-43°C), system performance pressures will be same as those for ambient temperatures shown on chart in 90-100°F (32-38°C) range. See Fig 1.
To determine compressor discharge (high) pressure, record ambient temperature. Record discharge (high) pressure. System performance is acceptable when pressure reading falls between upper and lower limits shown. See Fig 1.
