Fan noise under hood 2001 silverado 5.3
I have a random noise from under the hood. Sounds like engine is over-reving , like a diesel truck, but it's not,only 1600 rpm. It only does it after driving about 60 miles, if it does it at all, and never does it when i'm under the hood, so I can't tell where it's coming from. Have a long trip ahead, so i want to fix it. Anyone ever heard of anything like this?
Thanks
Thanks
