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
