Question about 1998 Mazda 626
It came off while driving, it is there, just cant figure how to replace it!
You may have to buy a new belt because that one may have stretches. After you buy a new belt. Look at he alternator, it has two screws, one hold it in place and the other allow it ti move. Lose both a little. With a pry bar push the alternator so the belt can fit. Look for the belt routing diagram in the engine compartment. Follow it and put the belt on. You were suppose to have a belt tension tool to determine the tension. Then use your pry bar to move the alternator to position and tension then tightened alternator screws.

You can loosen the alternator that should releive the tension on the belt.
When you tighten it again make sure you can only turn the belt 90 degrees then you know you have the right tension.

See Figures 1, 2, 3, 4 and 5
Check the condition and tension of all drive belts every 12,000 miles, or at least once a year. Loose drive belts can lead to poor engine cooling and diminished alternator, power steering pump, air conditioning compressor, or emission air pump output. A belt that is too tight places a strain on the bearings in the driven component.

Replace any drive belt that is glazed, worn, cracked, or stretched to the point where correct adjustment tension is impossible. If two belts are used to drive a component, always replace both belts when replacement is necessary. After installing a new belt, run the engine for ten minutes, shut OFF the engine and recheck the belt tension. Readjust if necessary.

Two popular methods of checking drive belt adjustment are; the Belt Tension Gauge Method and the Belt Deflection Method. The former requires a special gauge and the latter requires a straight edge and scale or just a good eye for measurement. The deflection method will be used in the following belt replacement instructions. A rule of thumb for checking belt tension by the deflection method is to determine the midpoint between two pulleys of the drive belt and press down at that point with moderate thumb pressure. The belt should deflect to the measurement indicated in the following installation procedures. Adjustment is necessary if the belt is either too loose or too tight.
WARNING A belt adjustment which is either too loose or too tight will eventually damage the accessory that belt is driving. A too loose adjustment allows free-play in the belt which could transfer a whipping motion or shock to the accessory drive pulley. Similarly, a belt which is too tight will preload the accessory bearings, leading to early failure.

If removal of the alternator belt is required, the A/C belt must first be removed.

When servicing the air pump, use the square holes provided in the pulley to prevent camshaft rotation.
