@the.car.brief: ENGINE NOISE? THE SOUND ALONE ISN’T A DIAGNOSIS Follow me to learn more about cars every day. A knock, tick, rattle, squeal or whine can point you toward a possible system, but the same sound can have more than one cause. When the noise happens matters — cold start, idle, acceleration, load and RPM can all change the diagnosis. Oil level and other symptoms matter too. Use this chart as a starting reference, not a one-sound/one-part diagnosis. Persistent or worsening noises deserve a proper inspection. #enginenoise #carproblems #carknowledge #fyp #carcare
