Volkswagen Polo Service & Repair Manual: Threaded Connections, Repairing

Special tools and workshop equipment required
Torque Wrench 1331 5-50Nm -VAG1331-
  Note
Do not use rust remover, contact spray or grease because the lack of friction will cause the torque to be exceeded when installing and this will lead to the threaded connection breaking.
The gray sanding pads are for slight contamination and suitable for "soft surfaces". The red sanding pads are for heavy contamination and suitable for "hard surfaces".
  WARNING
Risk of injury. Follow all Warnings and Safety Precautions. Refer to → Chapter „Warnings and Safety Precautions“.
–  Disconnect battery.
   
–  Loosen the cap nut and remove the wiring eyelet from the threaded connection.
–  Check the threaded connection for corrosion, contamination, etc.
–  Select the corresponding adapter and the corresponding sanding pad for the threaded connection.
  Caution
Make sure the tin layer is not worn down too much and the copper is not visible. A galvanic element can form from this, destroying the metal and causing incorrect repairs.
  Note
Due to the different thicknesses of the tin layer, the cleaning process must be performed in several steps and a visual inspection of the wiring eyelet between steps is necessary.
 

Threaded Connections, Repairing

–  Place the adapter on the threaded connection and sand off the corrosion and contaminants with circular movements.
–  Check the threaded connection and sand it again if necessary.
–  Retighten the connection and, if necessary, the anti-rotation protection to the specified torque. Refer to → Wiring diagrams, Troubleshooting & Component locations.
  Note
Optimal contact is ensured if the bolted components are tightened to the specified torque after cleaning.
–  Apply protection material to the threaded connection. Refer to → Chapter „Protecting“.
–  Reconnect the battery.
  WARNING
Risk of injury. Follow all Warnings and Safety Precautions. Refer to → Chapter „Warnings and Safety Precautions“.
