9. Lower the vehicle.
10. Remove the compressor manifold and tube assembly.
11. 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 .
    • Install new O-ring seals lubricated with clean refrigerant oil.
12. Evacuate, leak test, and charge the refrigerant system. See A/C REFRIGERANT SYSTEM TESTS .
