IMPORTANT: Seal the A/C compressor suction and discharge ports after the hoses are removed in order to keep contaminants from entering the A/C compressor and oil from draining out of the A/C compressor during removal.

All A/C lines, hoses and components should always be sealed after component removal in order to avoid excessive moisture contamination to the A/C system during servicing.

10. Remove the fastener (2) from the discharge hose (3) and disconnect the discharge hose (3) from the A/C compressor.




11. Remove the fastener (2) from the suction hose (1) and disconnect the suction hose fitting (1) from the A/C compressor.




12. Disconnect the A/C compressor electrical connector.




13. Remove the A/C compressor mounting fasteners (1,2,3,4).




14. Remove the A/C compressor (2) mounting stud (1).
