To change the alternator belt on a Mazda 323, first remove the right hand air shield under the can. Then locate the pulley tensioner of the AC and loosen the bolts on the pulley. Finally, remove the alternator pivot bolt under the alternator to remove the old alternator belt and replace with a new one.

This is from the Owners Handbook of my Mazda 323, 1996 : Alternator Drive Belt. 1. Loosen the alternator mounting bolt and adjusting bar bolt. Replace Fanbelt. 2. Turn the adjusting bolt until the correct tension is obtained. The deflexion should be 10mm. 3. Tighten bolts and recheck the tension.

Slacken the nut at the top of the alternator (14mm I think) and the bolt at the bottom. Pull alternator out until you can only get 10mm of movement in the belt on the longest run. Tighten bolts. You will need the car up and take the shield underneath off to get access.
First, disconnect the battery and then, remove the alternator and power steering belt, then the timing belt cover, the timing belt and the two pulleys, unscrew the pump bolts and that's it
It should be changed every 60,000 miles on all years 1988-94 with a timing belt. It is not an interference engine.
Most mfg. suggest to change it at 60k miles. Since your car has over 90k , Isuggest you change it as soon as possible, My 1989 car broke the belt and it bent valves and damaged head and pistons. Changing the belt is not expensive,
It means something is worng with your charging system. Check first your alternator if its charging. Check if belt is loose or broken. Check voltage of battery. Might be undercharged.
it is to the left of the engine beside your belt.
I was looking at the Gates website ( they make timing belts etc. ) and for the 1600 cc engine in a 2003 Mazda Protege ( Canada ) it shows ( 60,000 miles )
to hard.. get a mechanic to do it.......
