REMOVAL & INSTALLATION
See Figure 1
The accumulator/drier is a large aluminum canister located in front of the evaporator housing in the engine compartment.
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.
- Unfasten the wire at the pressure switch.
- Using an open ended wrench or equivalent, unscrew the pressure switch from the accumulator/drier.
- Tag and disconnect the suction lines from the accumulator/drier.
- Remove the 2 mounting bands securing the accumulator/drier in place, then remove the clamp from around the inlet tube.
- Disconnect the accumulator/drier from the evaporator outlet tube.
- Slide the accumulator out.
- Cap all openings at once to prevent debris from entering the system. Remove and discard the O-rings at each connection.
- Using new O-rings coated with clean refrigerant oil, connect the accumulator to the outlet tube. Make sure that the connections snap firmly into place.
- Slide the accumulator into the mounting clamps and tighten the fasteners to 15-18 inch lbs. (1.6-2.0 Nm).
- Using new O-rings coated with clean refrigerant oil, connect the suction lines to the accumulator. Make sure that all connections snap firmly into place.
- Install the pressure switch. Tighten a switch with a metal base to 10 ft. lbs. (13 Nm). If the switch has a plastic base, hand-tighten it only.
- Connect the wire harness to the pressure switch.
- 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.
