Lubricant Adjusting Procedure for Components Replacement Except Compressor

After replacing any of the following major components, add the correct amount of lubricant to the system.

Amount of lubricant to be added

● *1: If refrigerant leak is small, no addition of lubricant is needed.

Lubricant Adjustment Procedure for Compressor Replacement

1. Before connecting the recovery/recycling recharging equipment to the vehicle, check the recovery/recy-

cling recharging equipment gauges. No refrigerant pressure should be displayed. If OK, recover refriger-

ant from equipment lines.

2. Confirm refrigerant purity in supply tank using recovery/recycling recharging equipment and refrigerant

identifier. If NG, refer to MTC-3, "

Contaminated Refrigerant" .

3. Connect recovery/recycling recharging equipment to the vehicle. Confirm refrigerant purity in vehicle A/C

system using recovery/recycling recharging equipment and refrigerant identifier. If NG, refer to MTC-3,

"Contaminated Refrigerant" .

4. Discharge refrigerant into the refrigerant recovery/recycling recharging equipment. Measure lubricant dis-

charged into the recovery/recycling recharging equipment.

5. Drain the lubricant from the “old” (removed) compressor into a graduated container and recover the

amount of lubricant drained.

6. Drain the lubricant from the “new” compressor into a separate, clean container.

7. Measure an amount of new lubricant installed equal to amount drained from “old” compressor. Add this

lubricant to “new” compressor through the suction port opening.

8. Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant

to “new” compressor through the suction port opening.

9. If the liquid tank also needs to be replaced, add an additional 5 ml (0.2 US fl oz, 0.2 Imp fl oz) of lubricant

at this time.

Do not add this 5 ml (0.2 US fl oz, 0.2 Imp fl oz) of lubricant if only replacing the compressor.
