Belt Pulley, Removing And Installing, DENSO A/C Compressor: Notes

Belt pulley is sensitive to impact. Handle it with special care

If the belt pulley overload protection activates, check the A/C compressor for ease of movement before replacing the belt pulley. Replace an A/C compressor that is not operating smoothly.

If the drive plate overload protection has activated, the belt pulley can be rotated using the outer part of the drive plate so that the A/C compressor shaft and the hexagon head on the drive plate (inner part of the drive plate) do not rotate.

The following shows the A/C compressor on a vehicle with a 4-cylinder engine. On vehicles with a 5-cylinder engine with a ribbed belt on the A/C compressor the layout of the components is different however the removing and installing of the A/C compressor ribbed belt is performed in the same way. Refer to BELT PULLEY, REMOVING AND INSTALLING, SANDEN A/C COMPRESSOR  for vehicles with 5-cylinder engines with two ribbed belts on the A/C compressor.
