A/C Refrigerant System Pressures And Temperatures, Checking







The pressures and temperatures in the A/C system will vary depending on engine speed (RPM), coolant fan speed, engine coolant temperature, A/C clutch engagement, outside temperature, humidity, etc.

Pressure and temperature specifications are based on the following:
- Engine speed (RPM) at 1500
- Fresh air blower on high speed
- A/C adjusted to Max. cooling

1. Compressor, high pressure side
2. Condenser
3. Restrictor
4. Evaporator
5. Accumulator
6. Compressor, low pressure side
