PERFORMANCE TEST
1. The vehicle to be tested should be parked out of direct sunlight.
2. Close the high and low-pressure valve of the gauge manifold.
3. Connect the charging hose (blue) to the low-pressure valve and connect the charging hose (red) to the high-pressure valve of the gauge manifold.
4. Install the quick joint (for low-pressure) to the charging hose (blue), and connect the quick joint (for high-pressure) to the charging hose (red).
CAUTION:
- To connect the quick joint, press section A firmly against the service valve until a click is heard.
- When connecting, run your hand along the hose while pressing to ensure that there are no bends in the hose.
NOTE: The high-pressure service valve is on the liquid pipe A and the low-pressure service valve is on the suction hose.
5. Connect the quick joint (for low-pressure) to the low-pressure service valve and connect the quick joint (for high-pressure) to the high-pressure service valve.
6. Start the engine.
7. Set the A/C controls as follows:
- A/C switch: A/C - ON position
- Mode selection: FACE position
- Temperature control: MAXIMUM COOLING position
- Air selection: RECIRCULATION position
- Blower switch: "4" (HI) position
8. Adjust engine speed to idle speed with A/C clutch engaged.
9. Engine should be warmed up with doors and windows open.
10. Insert a thermometer in the center air outlet and operate the engine for 20 minutes.
NOTE: If the clutch cycles, take the reading before the clutch disengages.
11. Note the discharge air temperature.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
