AV-SCANNER / Accessory guides / Tyres, brakes and cooling
This guide gives you a complete, professional procedure for using a coil spring compressor safely on MacPherson struts and similar suspension layouts. It covers the tool types, how to choose and inspect them, the full step-by-step compression and release sequence, and how to read spring free length and installed height with worked examples. You will also see typical diagnostic jobs, common mistakes, care and calibration routines, and clear criteria for handing the job to a professional. After working through it, you will be able to compress and release a coil spring with controlled, measured steps and recognize when the risk exceeds your equipment or experience.
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.
