🔩 Torque settings
Values can differ between engine variants — check the code stamped on your block.
| Torque | Fastener / step |
|---|---|
| 10 Nm (7.4 lb-ft) | Tighten bolts |
| 15 Nm (11 lb-ft) | Tighten bolts |
| 22 Nm (16 lb-ft) | Tighten bolts |
| 23 Nm (17 lb-ft) | Tighten bolts |
| 23 Nm (17 lb-ft) | Tighten in diagonal sequence |
| 25 Nm (18 lb-ft) | Tighten bolts |
| 40 Nm (30 lb-ft) | Tighten bolts in the sequence |
ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.
📋 Procedure
- ⚠ If a used belt runs in the opposite direction when it is refitted, this can cause breakage.Before removing, mark direction of rotation of poly V-belt with chalk or felt-tip pen for re-installation. — Tighten bolts in the sequence (1 ... 5) in 2 stages as follows:
- Tighten bolts hand tight.
- Tighten bolts to 25 Nm. [Note: Bolts (1) and (2) are fitted bolts.] — 25 Nm (18 lb-ft)
- Tighten bolts in 3 stages as follows:
- Screw in bolts (1 ... 11) hand-tight.
- Tighten bolts (1 ... 6) in diagonal sequence and in stages to 10 Nm. — 10 Nm (7.4 lb-ft)
- Tighten bolts (7 ... 11) to 10 Nm. — 10 Nm (7.4 lb-ft)

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.
