2008 Saturn Vue Q&A
2008 Saturn Vue Question: buzzing sound from under the hood.. Belt?
Sounds like one of your pulleys may make a buzzing noise. Perhaps the power steering pump or alternator pulley bearing may be noisy. Best thing to do is have the belt removed, spin each pulley manually and check for any restriction or grinding sensation. Hard to say. Good luck. - DaveJHM
If not engine replated suggest checking the hood stops. Adjust if the hood vibrates. - calaway
