Q: Loose belt sound under hood

asked by on

I can hear a noise from under the hood when the blower is engaged. It sounds like a loose belt, but it is not. It has something to do with the AC.

Hi there, even if your belts are tight, over time they can heat up and develop a glazed area which is very slippery. Do not tighten the belt more as you can damage the components attached to them. My recommendation is to have a certified technician inspect the belts and help you find the cause of the sound.
