🔩 Torque settings
Values can differ between engine variants — check the code stamped on your block.
| Torque | Fastener / step |
|---|---|
| 4 Nm (3.0 lb-ft) | Tighten M5 securing nuts (1) |
| 6 Nm (4.4 lb-ft) | Tighten M6 securing nuts (1) |
| 6 Nm (4.4 lb-ft) | Unscrew the eight securing bolts (2) and remove centre part (3 |
| 6 Nm (4.4 lb-ft) | Unscrew the nine securing bolts (5 |
| 7 Nm (5.2 lb-ft) | Unbolt cable (PIN 10) (1) and place it to one side |

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
