REMOVAL

NOTE: Installation of a new suction accumulator is not required when repairing the refrigerant system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

1. Recover the refrigerant.
2. Remove the engine cooling fans.
3. Raise and support vehicle.
4. Drain the cooling system.







5. Remove the lower radiator hose, reservoir supply hose, and the radiator lower tube bolt.







6. Disconnect the following:
- A/C pressure switch.
- Catalyst monitor sensor.
- Push pin from the bracket.







7. Disconnect the A/C clutch electrical connector.
8. Lower the vehicle.







9. Remove the radiator upper tube bolt, and disconnect the radiator vent tube.







10. Disconnect the upper radiator hose and engine vent hose.







11. Disconnect the oxygen sensor connector retainer and harness pin-type retainer.







12. Remove the two bolts, and remove the radiator tube assembly.







13. Disconnect the compressor manifold and tube assembly peanut fitting from the condenser.
- Discard the O-ring seal.

14. Disconnect the pressure cutoff switch electrical connector.
15. Lower the vehicle.







16. Detach the wiring harness.







17. Loosen the bolt and disconnect the compressor manifold and tube assembly from the A/C compressor.
- Discard the O-ring seals.







18. Disconnect the compressor manifold and tube assembly spring lock coupling from the suction accumulator.
- Discard the O-ring seals.

19. Remove the compressor manifold and tube assembly.

INSTALLATION
1. To install, reverse the removal procedure.
