i've been experiencing a weird humming sound from my 3.0 accord coupe engine bay. it gets higher pitched durring acceleration and stays the same durring idle. it kinda sounds like when a suv turns slowly ( that squeel sound) and a turbo charger idle...help please
P.S: i just made a 700 mile trip to college if the distance could have played a factor

 

It can be a couple things. It could be the alternator, which would mean your working it hard or its getting older. That or its a belt, in which case you should buy belt conditioner and you should be golden
