10. Install the suction filter in the suction hose close to the A/C compressor. Suction filter is for nylon lined core hose. These filters have two
grooves in the end tubes to accommodate O-ring seals.
NOTE: It will be necessary to transfer the A/C clutch from the old A/C compressor to the replacement A/C compressor.
11. Remove a length of suction hose (close to the A/C compressor end) to accommodate the suction filter and install the filter using A/C hose
clamps. Be sure filter is correctly oriented for refrigerant system flow. Check the label on the filter. If using the filter for a nylon lined hose,
install O-ring seals included in the Filter Kit (two on each filter tube).
12. Leak test, evacuate, and charge the system. See: Service and Repair
13. Check all refrigerant system hoses, lines, and the positioning of the newly installed filters to be sure they do not interfere with other engine
compartment components. If necessary, use tie straps to make adjustments.
14. Set the A/C control on MAX A/C, high blower motor and temperature control at full cold. Start engine and let it idle briefly. Make sure the
A/C system is operating properly.
15. Gradually bring the engine up to 1200 rpm by running it at lower rpms for short periods (first at 800 rpm, then at 1000 rpm). Set the engine
at 1200 rpm and run it for an hour with the A/C system operating.
16. Stop the engine.
17. Recover the refrigerant from the system using a recovery machine. See: Service and Repair/Refrigerant Recovery
18. Allow the engine to cool sufficiently to remove the fittings, flexible hoses and pancake filter from the condenser to evaporator tube.
19. Discard the pancake filter. It can be used one time only.
20. Reconnect the condenser to evaporator tube back into the system.
21. Evacuate, charge, and leak test the system. Make any necessary adjustments. See: Service and Repair
22. Check the operation of the system in all control function selector lever positions.
