Volkswagen Golf Service & Repair Manual: Removing and installing Denso belt pulley

  Note
The pulley is sensitive to impact and should therefore be treated with extreme care.
If the belt pulley overload protection has deployed, check freedom of movement of air conditioner compressor before renewing belt pulley. If air conditioner compressor cannot rotate freely it must be renewed.
If the drive plate overload protection device has been triggered, the pulley can rotate with the outer section of the drive plate without the air conditioner compressor shaft and the hexagon flats attached to the drive plate (inner section of drive plate) also rotating.
Special tools and workshop equipment required
Commercially available oil filter strap wrench
