2. Disconnect the condenser outlet fitting and temporarily install the pancake filter between the 2 halves of the fitting.
a. Use flexible refrigerant hose of 17,238 kPa (2,500 psi) burst rating.
b. 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.
3. Lubricate the refrigerant system with the correct amount of PAG oil. See See: Service and Repair/Refrigerant Oil Adding.
4. Evacuate and charge the refrigerant system. See See: Service and Repair/Air Conditioning (A/C) System Evacuation And Charging.
5. Check all refrigerant system hoses, lines and the newly installed filters to be sure they do not interfere with other engine compartment components.
If necessary, use tie-straps to make adjustments.
6. Provide adequate airflow to the front of the vehicle (with a fan, if necessary). Select 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.
7. Gradually bring the engine up to 1,200 rpm by running it at lower rpms for short periods (first at 800 rpm, then at 1,000 rpm). Set the engine at
1,200 rpm and run it for one hour with the A/C system operating.
8. Stop the engine.
9. Recover the refrigerant. See See: Service and Repair/Air Conditioning (A/C) System Evacuation And Charging.
