Section 61 (Air Conditioning (Service Information)): Compressor: Inspection: Inspection

WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT MAGNETIC CLUTCH CLEARANCE
1. Set the dial indicator to the magnetic clutch hub.

2. Connect the battery positive lead to terminal 3 of the magnetic clutch connector and the negative lead to the earth wire. Turn on and off the magnetic clutch and measure the clearance.
  Standard clearance
  
  0.26 to 0.60 mm (0.010 to 0.024 in.)
  
  If the measured value is out of the standard range, remove the magnetic clutch hub and adjust it with the magnetic clutch washers.
  
  NOTE:
  Adjustment shall be performed with 3 or less magnetic clutch washers.
3. Remove the compressor and magnetic clutch from the vise.
INSPECT COMPRESSOR OIL
1. Gradually discharge the refrigerant gas from the service valve when replacing the compressor and magnetic clutch with a new one. Drain the following amount of oil from the new compressor and magnetic clutch before installation.
  Standard
  
  (Oil capacity inside the new compressor and magnetic clutch: 130 + 15 cc (4.6 + 0.51 fl.oz.) - (Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be removed before installation)
  NOTE:
  - When checking the compressor oil level, observe the precautions on the cooler removal / installation.
  - Because compressor oil remains in the pipes of the vehicle, if anew compressor and magnetic clutch is installed without removing some oil, the oil amount becomes too much, preventing heat exchange in the refrigerant cycle and causing refrigerant failure.
  - If the remaining oil the removed compressor and magnetic clutch is too small in volume, check for oil leakage.
  - Be sure to use ND-OIL8 for compressor oil.

INSPECT W/MAGNET CLUTCH COMPRESSOR ASSEMBLY

Disconnect the connector from the w/ magnet clutch compressor assembly.

Measure the resistance according to the value(s) in the table below.

Resistance

Tester connection	Condition	Specified condition
B8-3 - Body Ground	Always	Below 1 Ω

If the resistance is not as specified, replace the w/ magnet clutch compressor assembly.
