PERFORMANCE TEST CONDITIONS

  Vehicle indoors or in the shade

 Doors 

closed

 Windows 

open

 Hood 

open

  Temperature on "Max" setting

  Discharge air on "Face Vent"

  Recirculation switch on "Recirc"

  Fan speed on "High"

  A/C switch "On" and verify A/C Clutch engagement

  Engine speed at idle

  Operate the A/C system for 10 minutes before taking measurements

Precautions:

1. When removing the compressor, store it in the same position as it is mounted in the vehicle.

Failure to do so may cause lubricant to enter the low pressure chamber and cause compressor
damage.

2. Allow components stored in cool areas to warm to area temperatures before removing seals.

This prevents condensation from forming inside A/C components.
