AV-SCANNER / Accessory guides / Engine and fuel
This guide gives motorists and working mechanics a complete, practical method for choosing, setting up, using, reading and maintaining a torque wrench across a wide range of vehicle repairs. It explains the common wrench types, how to match drive size and range to the fastener, how to connect sockets safely, and how to work through a full tightening sequence with worked examples. Readers will also learn to recognise false readings, avoid the mistakes that damage threads and tools, store and verify calibration, and judge when a job needs a specialist. After working through it, you will be able to select the right torque wrench for a task, apply a specified figure correctly, and document the result with confidence.
Guidance is general and covers many makes. Exact procedures and values vary by model, so confirm them in the factory service information for your vehicle.
