SOURCE: 2003 galant serpentine belt replacement

pick up a belt at you local auto parts store you wont need a jack just a couple of metric wrenches and a rachet. under the hood will be the routing for the belt . follow it exactly. make sure all the pulleys spin . they all will except the crank. if any other one doesnt spin you found the reason the belt broke. let me know if you cant find the diagram ill send it to ya.
hope this helps

SOURCE: Belt squealing when first started

The squeal when first started is most likely coming from the alternator belt. You need to have the tension of the belt checked to make sure it is properly adjusted. If you had a shop due it have , have them recheck it. Or stop by a local shop and they shouldnt charge you to check it. But its all in how you ask, if you go in and tell them your problem most likely they will try to get you for a fee to diagnose it.Just ask to have them check the belts and make sure there tight.If its ok, has anyone tried to fix your sqeul by spraying anything on it? if so your belt could be slipping from the lube they used. there is one more thing you can try, providing all the pullys/ tensioner pully if equiped are straight. If it is a serpantine belt(flat/multiple grooves) not A v-belt
when the engine is off,you take a tablespoon or so of corn starch, yes the stuff in the yellow box in the kitchen, and put it on the inside oif the belt. Its acts like a dry lube. I learned this trick at the GM dealership, from a factory bu;lliton. good luck

There should only be about 1/2" deflection on the belts if you push down with your fingers. If they are ok i would suggest you investigate your alternator first , then last resort water pump bearing.(new water pump)

SOURCE: How do i change belt on mitubishi mirage 98

( BEFORE ADJUSTING THE ALTERNATOR BELT DISCONNECT THE NEGATIVE BATTERY CABLE OR YOU MIGHT BLOW AN EXPENSIVE HIDDEN FUSE)to change the alternator belt, you have to loosen the lower mount bolt on the alternator, loosen block shaped bolt that the long adjuster bolt goes through, and loosen the belt by turning the long adjuster bolt, take off the belt. to adjust the power steering belt, there is a long adjuster bolt that moves a tensioner pulley, first you have to loosen the nut that holds the pulley in place , now the pulley can be moved with the adjuster bolt.

Makes squealing noise

You need to check the belt that drives the alternator for proper operation. The belt may be old and worn, or a pulley may be not freewheeling, but seized or with a bad bearing. Possibly the tension on the belt is too loose from a worn out tensioner.

First, spray a little water on the belt with engine running and see if noise goes away, possibly a worn belt. Pull the belt off and check all pulleys. Spin them by hand and see if spins easy, no rough feeling or a catch when spun. Check alternator pulley, idler pulley, tensioner pulley, PS pump pulley and A/C compressor pulley-check them all for free wheeling. If good check the tension on the belt when installed. If unsure, have a mechanic check tension with a belt tension tool.
If belt is good and pulleys good, check alternator output with a voltmeter on the battery with engine running. If voltmeter is below 13.5 volts, the charging system is still not working properly. Have it checked out.

Could it be the pulley on the AC that's squealing? Use a mechanic's stethoscope to locate the squeal. If it is the AC, you can get a belt that is shorter, and bypass the pump, since it doesn't work anyway. Try some belt dressing first. When the engine is running, just spray it on the inside of the belt.

Alternator drive belt squealing

yeh, mine did the same thing with a hydralic belt. it was the bearings. mazda capellas use a lot of 6202 bearings which, luckily, are fairly cheap, and are commonly used in pool pumps. so you can find them at pool pump repair stores. although pool pumps use 6202 2RSR bearings. these are just the water proof type, but are excactly the same size and can be used.
to test if it is a bearing problem, remove the belt and try to twist the individual wheels by hand, you should be able to turn the 2 smaller ones.
from memory the alternator belt is in a fairly in accessable postition so the belt is going to be hard to put back on.try other things first, like wiping the inner side of the belt with a dry cloth to remove moisture.
worst case senario is your alternator has, or is starting to, seize up and you need to replace it.
