Wear safety goggles and gloves when servicing the refrigeration system to prevent severe damage to the eyes and hands.
1.
Referring to the appropriate service manual, discharge the air conditioning system, then remove the A/C compressor.
2.
Remove the high-pressure relief valve from the top of the A/C compressor. Install the new valve and tighten to 12 Nm (106 in.lb).
3.
After installing the relief valve on the compressor, make the following inspections (to determine the cause by which the relief valve operated)
before installing the compressor on the vehicle.
a.
Check the air conditioner compressor clutch relay. (Refer to Service Manual).
b.
Check that the compressor pulley is free to turn. If it is not free to turn, replace the magnetic clutch.
c.
Perform an operational check of the air conditioner compressor clutch. (Refer to Service Manual).
4.
Before installing the compressor on the vehicle, fill it with compressor oil according to the following procedure.
5.
Using the steps in the service manual, reinstall the A/C compressor and recharge the system. Check the cooling efficiency of the system to make
sure it has the proper temperature drop before returning the vehicle to the customer. Check the high pressure reading of the system. If the reading
is above the standard operating pressure of the valve (3.5 - 4.1 Mpa [508 - 595 psi]), there is another component or system failure. Use the service
manual to diagnose and determine the cause of the problem.
