Car Noises: Squeaky Brakes, Engine Noises & More | ACDelco

 

 

What’s your vehicle trying to tell you when it clicks, clunks or grinds? Translating these car noises is key for automotive technicians who are trained to identify problems via sound. The important thing to remember is to be specific. Narrow that rattle down and then document when it happens – details such as when the car is hot, cold, at idle, moving at 55 mph, etc. can go a long way in helping to diagnose the problem.
