A/C Refrigerant Oil Replacement

Special Tools Required 

Oil Injector Tool Robinair ROB16256*, commercially available

*Available through the Acura Tool and Equipment Program; call 888-424-6857

Recommended PAG oil: DENSO ND-OIL 8

P/N 38897-PR7-A01AH: 120 mL (4 fl.oz)

It is important to have the correct amount of refrigerant oil in the A/C system to ensure proper lubrication of the A/C compressor. Too little oil damages the A/C compressor; too much oil reduces the cooling capacity of the system, and can produce high vent temperatures.

Add the recommended refrigerant oil in the amount listed if you replace any of the following parts:

A/C condenser (including Dryer Desiccant)..............35 mL (1 1/5 fl.oz)

Evaporator............35 mL (1 1/5 fl.oz)

Line or hose..........10 mL (1/3 fl.oz)

Dryer desiccant.....10 mL (1/3 fl.oz)

Leakage repair.... 25 mL (5/6 fl.oz)

A/C compressor.... For A/C compressor replacement, subtract the volume of oil drained from the removed A/C compressor from 82 mL (2 7/9 fl-oz), and drain the calculated volume of oil from the new A/C compressor: 82 mL (2 7/9 fl-oz) - Volume of removed A/C compressor = Volume to drain from new A/C compressor.

NOTE: Even if no oil is drained from the removed A/C compressor, do not drain more than 50 mL (1 2/3 fl.oz) from the new A/C compressor.
