A/C Component Replacement Requirements
SYSTEM FILTERING AFTER A/C COMPONENT REPLACEMENTSet, A/C Fittings:
SPECIAL TOOL(S)
1. Install the new A/C compressor.
2. Install the new suction accumulator/drier.
3. Install the new A/C evaporator core orifice.
4. Orient the filter inlet toward the A/C condenser core.
5. Temporarily install the pancake filter between the A/C condenser core and the condenser to evaporator tube.
1 Use flexible refrigerant hose of 17,238 kPa (2500 psi) burst rating.
2 Make the connections using the A/C Test Fitting Set.
NOTE: The pancake filter is not permanently installed and will be removed at the end of this procedure.
6. Correctly oil match the system.
7. Evacuate and charge the system.
8. 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.
9. Provide adequate airflow to the front of the vehicle (with a fan, if necessary). Select MAX A/C operation and set the blower motor speed to maximum. Start the engine and let it idle briefly. Make sure the A/C system is operating correctly.
10. 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 one hour with the A/C system operating.
11. Stop the engine.
12. Recover the refrigerant from the system.
13. Remove the fittings, flexible hoses and pancake filter from between the A/C condenser core and the condenser to evaporator tube.
14. Discard the pancake filter. It can be used one time only.
15. Reconnect the condenser to evaporator tube to the A/C condenser core.
16. Evacuate and charge the system.
