AV-SCANNER / Accessory guides / Diagnostic
This Auto Veteran guide delivers a complete professional workflow for using an inspection videoscope to see inside cylinders, behind panels, and into otherwise inaccessible cavities on any vehicle. It is written for working mechanics and serious DIYers who already own basic hand tools and want to add borescope diagnostics to their skill set. You will learn how to select the right scope, set it up safely, navigate it without damaging delicate components, interpret what you see on screen, and decide when a finding demands a teardown or a specialist. By the end you will be able to perform a structured visual inspection, document your results, and avoid the common mistakes that turn a useful tool into an expensive hazard.
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.
