Depending on the model there will be a couple of screws on the top plastic cover. The cover lifts off and the belt is then serviceable. On some models you will need to remove some parts on the bottom too to get the roller out.
In any case just look for screws that hold the covers on and explore a bit. You can't break anything.

Just by what you explained I can tell that it needs to be replaced. The belt doesn't have to be broken to need replacing, if it is stretched and worn then it will slip on the motor shaft and not turn the brush roll and get hot. Here is a link to the belts you need and the manual which has instructions:

it could be the beater bar (brush) has bad bearings at the ends or burs on the beater bar section the belt rides on,my money is on the bearings.
