• | J 42220 Universal 12 V Leak Detection Lamp |
• | J 43600 ACR 2000 Air Conditioning Service Center |
• | J 45268 A/C Flush Adapter Kit |
Note: Flushing with the J 43600 is not intended to remove metal from the A/C system.
Flushing is intended to remove the following:
• | Contaminated polyalkylene glycol (PAG) oil |
• | Desiccant, following a desiccant bag failure |
• | Overcharge of PAG oil |
• | Refrigerant contamination |
Note:
• Forward flow refrigerant flushing is recommended for contaminated refrigerant or PAG oil. • Inspect and lubricate the sealing washers
J 45268 . Refer to
Sealing Washer Replacement.
Note:
• Reverse flow refrigerant flush is recommended for desiccant bag failure. Replace the condenser/receiver dehydrator assembly when the A/C flush is complete and perform the following procedure: • Inspect and lubricate the
J 45268 sealing washers. Refer to
Sealing Washer Replacement.
Note: Warmer engine or ambient temperatures decreases the refrigerant recovery time during the A/C flush procedure.
Caution: Refer to Fastener Caution in the Preface section.
Tighten
Tighten the bolts to 7 N·m (62 lb in).
Tighten
Tighten the nut to 20 N·m (15 lb ft).
Note: The filter inside J 45268-1 is serviceable. Remove and discard the check valve from the filter.
Note: Install new sealing washers onto the compressor hose assembly. Refer to Sealing Washer Replacement.
Assure that the suction and discharge ports on the J 45268-10 correspond to the suction and discharge ports on the compressor hose assembly.Note: Close the valve on the external refrigerant tank, before starting the flush process.
Note: Flushing will remove all the PAG oil from the A/C system.
The A/C system must be replenished with the correct amount of PAG oil.21.1. | Remove the A/C compressor drain plug. |
21.2. | Drain the PAG oil from the A/C compressor. Rotate the compressor input shaft to assist in draining the PAG oil from the compressor. |
21.3. | Add the total system capacity of PAG oil to the crankcase of the A/C compressor. Refer to Refrigerant System Capacities. |
Note: Flushing will remove the fluorescent leak detection dye from the A/C system. |
21.4. | Add one bottle of J 41447 directly into the A/C compressor. |
21.5. | Install the A/C compressor drain plug. |
Tighten
Tighten the drain plug to 15 N·m (11 lb ft).
Note: A new service compressor is shipped with a partial charge of PAG oil. Refer to Refrigerant System Capacities.
