REMOVAL & INSTALLATION
See Figures 1 and 2
This procedure requires the evacuating and recharging of the A/C refrigerant. An approved recycling/recovery machine is needed to do this. If you do not have the proper certification in addition to the necessary equipment, you must consult a certified professional to evacuate the system before you start the procedure, and recharge the system when the job is complete.
- Determine whether your particular A/C system uses R-12 or R-134a refrigerant. Most vehicles have identification stickers placed in the engine compartment and on certain components of the A/C system to alert you to which type of refrigerant is used.
- Have the A/C refrigerant properly evacuated using an approved recovery/recycling machine.
- Disconnect the negative battery cable.
- Disconnect the condenser to evaporator tube from the evaporator core. Cap the open connection to prevent debris from entering the system.
- Squirt a small amount of refrigerant oil into the inlet tube. engage orifice tube remover T83L-1990-A or equivalent with the tangs on the orifice.
- Remove the orifice from the tube. Remove and discard the O-rings.
- Install the orifice into the tube using new O-rings coated with clean refrigerant oil. Use tool T88L-1990-A or equivalent. Continue turning the tool until the orifice bottoms out in the tube, then remove the tool.
- Remove the protective cap and install the condenser-to-evaporator tube to the evaporator core.
- Connect the negative battery cable.
- Charge the A/C using an approved recovery/recycling machine.
- Run the A/C system and check to make sure it functions correctly.
