How do you tighten belt onto a new alternator.?
If it is a serpentine belt, the tension is automatically adjusted by the tension idler. If the belt is loose then the tensioner needs replacing. If it is a normal drive belt, then the alternator is mounted on a slotted bracket that allows you to adjust the position of the alternator. You can loosen the bolts and adjust the tension on the belt.
How do you change a serpentine belt on a 1990 GMC suburban?
My suburban has a automatic tensioner therefore I need to do is take the tension off with a long wrench and slide the belt from underneath it and replace it with the new one. The tensioner is right by the water pump. If not then you will need to loosen the alternator bolt and drop the alternator to loosen the tension. Trust me manuals can be your best friend!!

If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.

How do you tighten a serpentine belt for a 1998 Ford Contour?
Buy a Chevy!!!! That was a big help. Most but not all serpentine belt systems have a spring loaded tension pulley that just holds constant tension on the belt. If there is a tension pulley, it will be the one pulley that is not attached to anything like the alternator or AC. After that, the alternator is the most likely to be the one that adjusts.
How do you tighten the serpentine pulley on the alternator?
You don't. The tension on the belt is held tight by a spring loaded tensioner idler.
