CHECKING AND ADJUSTING
Adjust the lubricant quantity according to the test group shown below.
- CHECK LUBRICANT RETURN OPERATION Can lubricant return operation be performed? A/C system works properly. There is no evidence of a large amount of lubricant leakage. Yes or No Yes : GO TO 2. No : GO TO 3 .
- PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS: Start engine, and set the following conditions: Test condition Engine speed: Idling to 1,200 RPM A/C or AUTO switch: ON Blower speed: Max. position Temp. control: Optional [Set so that intake air temperature is 25 to 30°C (77 to 86°F ).] Next item is for V-6 compressor. Connect the manifold gauge, and check that the high pressure side pressure is 588 kPa (6 kg/cm 2 , 85 psi) or higher. If less than the reference level, attach a cover to the front face of the condenser to raise the pressure. Perform lubricant return operation for about 10 minutes. Stop engine. CAUTION: If excessive lubricant leakage is noted, do not perform the lubricant return operation. OK : GO TO 3.
- CHECK COMPRESSOR Should the compressor be replaced? Yes or No Yes : GO TO , " «LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT»(ref-180428-S39659311552005072600000) ". No : GO TO 4.
- CHECK ANY PART Is there any part to be replaced? (Evaporator, condenser, liquid tank or in case there is evidence of a large amount of lubricant leakage.) Yes or No Yes : GO TO , " «LUBRICANT ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COMPRESSOR»(ref-180428-S02295465412005072600000) ",. No : Carry out the A/C performance test.
