HEATING / AIR CONDITIONING: COMPRESSOR (for 2ZR-FXE): INSTALLATION; 2020 - 2022 MY Corolla Corolla HV [01/2019

(a) When replacing the compressor with motor assembly with a new one, gradually discharge the inert gas from the service valve, and drain the following amount of oil from the new compressor with motor assembly before installation.

(Oil capacity inside the new compressor with motor assembly: 110 to 125 cc (3.73 to 4.22 fl. oz)) - (Remaining oil amount in the removed compressor with motor assembly) - 65 cc (2.20 fl.oz) = (Oil amount to be removed from the new compressor)

NOTICE:

When checking the compressor oil level, observe the precautions on the cooler removal/installation.
If a new compressor with motor assembly is installed without removing some oil, there will be too much oil in the system due to the oil remaining in the pipes of the vehicle. Excessive oil in the system prevents heat exchange in the refrigeration cycle and causes ineffective cooling.
If the amount of oil remaining in the old compressor with motor assembly is too small, check the air conditioning system for oil leaks.
Be sure to use ND-OIL 11 or equivalent compressor oil. If any compressor oil other than ND-OIL 11 is used, compressor with motor assembly insulation performance may decrease, resulting in leakage of electric power.
Make sure to drain compressor oil from the intake port.
Make sure to add compressor oil from the intake port.
If the amount of oil from the removed compressor with motor assembly plus an additional 65 cc (2.20 fl.oz) is then greater than the amount of oil in a new compressor with motor assembly, do not drain the compressor oil from the new compressor with motor assembly.
When it is not possible to confirm the amount of oil in the system such as when compressor oil is spilt due to damage caused by a vehicle collision, etc., install a new compressor without draining any oil. If also replacing the cooler condenser assembly, do not add the supplied oil (40 cc (1.35 fl.oz)).
