Hi Everyone,

i noticed lately my engine sounds like there is a large fan under the hood instead of the nice motor noise it used to be. it almost seems as the fans run all the time and when i accelerate the fans get louder too .... weird, anything you can think of that may be wrong?

thanks !

At first I was thinking that your electric fan was stuck on HI, but if the noise is following RPM, you may have a stuck fan clutch. A bad clutch bearing will cause a noise, but it's more like a squeak or grinding noise to my ear. Either way it's worth a look.

R&R procedure is in the FSM page CO-14
