Hi Im not sure if this question was already posted i know next to nothing about car im slowly learning but i hope some one and help me if not lead me in the right direction
2001
Chevrolet
Cavalier
2.0 or 2.2 (i really dont know what that means but i know is a 4-cylinder)
120,000 miles (dont really know odometer is not working right)
Ive had the car for about 3 years about a month ago I was adding coolant and a day or two after the belt on the side (have no clue what its called) came off, a friend of mine who knows a good bit about cars helped me put it back on he told me its fine and that I didn't need to replace it unless it was broken and things were fine until about two weeks ago when ever i made a left turn it would make this loud humming noise as if something were rubbing against something and now it making the humming whenever i accelerate i think the humming is coming from the right side under the hood the same side that the belt is on but when i look at the belt its still on and attached to everything and turning i hope this is enough i'm in college so money is a BIG issue considering i have none any help is appreciated Thank you

Check that belt's tension first then I'd take it off and spin the pulleys. Any wobble or sounds from the idler pulley or pulley on tensioner noted? Spin them all for anything unusual. You added coolant so pay attention to the water pump as well. This is higher on the suspect list with coolant loss, noise and you might notice some anti-freeze under it.
The belt came off already and that's unusual. That could be a pulley failing, tensioner not providing quick and automatic tension to keep in snug all the time, belt could be stretched to range limit of the tensioner. The power steering fluid if low can make a growling, buzzing sound so check all the belt driven items carefully.
The noise being exaserbated by steering could just be the added load of the pump on the belt causing issues with another items bearing on its pulley.
Suffice it to say that belts don't just fall off (whole and intact) so this problem should make itself apparent,
