Volkswagen Golf Service & Repair Manual: Removing and installing decoupler pulley with freewheel
| There are different versions of decoupler pulleys with
freewheel. |
| Before removing the decoupler pulley with freewheel, it must
be determined which special tool must be used. |
Caution
| The length of the poly V-belt depends on the version
of decoupler pulley with freewheel installed. |
| Please check which type of the decoupled pulley with
freewheel is installed in order to ensure installation
of the correct poly V-belt. Refer to ETKA for proper
allocation of the poly V-belt. |

freewheel, small; use special tool T10474 |

depending on the installation of an air conditioning system in
the vehicle. |
