If it is a serpentine belt is is self adjusting. So if it is squealing then it needs replacing as it is worn out. And also possibly the tensioner needs replacing as it may not be holding sufficient tension on the belt. If it is a drive belt it more than likely still needs replacing as it will have become glazed from slipping. On a drive belt it is adjusted by loosening the mounting bracket on the A/C and moving it in a direction that tightens the belt.

Most car manufacturers recommend replacing timing belts after 60,000 miles. I have seen cars go 200,000 on a timing belt. But I wouldn't recommend that. Personally, that Max I would go, even if 99% of your driving is highway, is 80,000 miles. I'm not 100% sure about the sonata, but if it is front wheel drive and your replacing the timing belt, think about replacing the water pump at the same time. That is always good practice to remember.

timing belt and most drive belts are good for 70,000miles, i think the mechanic trying to take you for a ride, as for the drive belts inspect them if there is any cracking ware marks etc replace them but seriously if they look like new which they should with only that many miles would not need replacing.

2.0L Engines
See Figures 11, 12 and 13
The accessory drive belt for 2.0L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner.
Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension.
The belt tensioner has a belt length indicator. If the indicator marks are not between the MIN and MAX marks, the belt must be replaced.
