A/C MANIFOLD AND TUBE ASSEMBLY REMOVAL / INSTALLATION

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




1. Disconnect the compressor manifold and tube assembly from the receiver/drier. See the Spring Lock Coupling Disconnect and Connect general procedure in See A/C SPRING LOCK COUPLING.
- Discard the O-ring seals.




2. Disconnect the compressor manifold and tube assembly from the condenser core.
- Discard the O-ring seals.




3. Disconnect the A/C pressure cut-off switch connector.




4. Disconnect the fuel line spring lock coupling, see SPRING LOCK COUPLINGS.




5. Remove the nut and reposition the bracket.




6. Loosen the bolt and remove the compressor manifold and tube assembly.
- Discard the O-ring seals.

7. To install, reverse the removal procedure
- If a new compressor manifold and tube assembly is to be installed, transfer the pressure cutoff switch to the new compressor manifold and tube assembly.
- Lubricate the refrigerant system with the correct amount of clean refrigerant oil. See A/C REFRIGERANT OIL ADDITION.
