System Performance Test

This performance test evaluates the condition of all system components. Follow these steps for optimal results:

1. Start the engine and operate it at 1200 to 1500 RPM.
2. Position a fan in front of the condenser to simulate typical air flow and stabilize the system.
3. Insert a thermometer into the air conditioning vent closest to the evaporator.
4. Compare gauge readings against ambient temperature standards.
5. Preliminary steps include:
   • Close all cab windows and doors.
   • Set the air conditioning to maximum cooling and blower speed.
   • Ensure manifold gauge readings are within the normal range relative to ambient temperature.
   • Verify the evaporator discharge air temperature aligns with recommended settings for the current conditions.
   • Check hoses and components on the high side for warm-hot temperature. If the receiver-drier outlet is cooler than the inlet, a restriction is indicated.
