Inspection of the Air Conditioner
122SD mm 83.01.01
- Park the vehicle on a level surface, apply the parking brakes, and chock the tires.
- Inspect the A/C compressor hub. A torn or melted rubber dampener (center section) indicates internal damage has occurred within the compressor. Inspect friction surfaces for wear, oil-soaked condtions, or discoloration due to excessive heat.
- With the belt removed, check to make sure that the rotor (pulley) spins freely. It should not wobble or make contact with the hub when it is spinning. The average air gap between the hub and rotor should be 0.014 to 0.024 inch (0.35 to 0.6 mm). Check the gap at several locations and average the results. See Fig..
- Check the overall condition of the air conditioning hoses.
Look for cracks, cuts, and abrasions on the hoses. Replace damaged
hoses. For replacement instructions, see Group 83 of
the 122SD and Coronado Workshop Manual. Also check for
signs of loose fittings on all of the air conditioning components.

Warning: Wear eye protection, gloves, and protective clothing when working on the air conditioning system. Leaking refrigerant from a damaged hose or line could cause blindness or serious skin burns.
