My serpantine belt has been dislocating many times from alternator, how to improve this situation? should I change the alternator with a new one? My Car is Suzuki Aerio 2004, please help me to solve this problem. Thank you

you have to remove the serpantine belt and then the alternator has 2 bolts one top one bottom remove both it slides out put new in put new serpintine belt on good to go 2 hour job

take an 11/16 wrench and turn tensioner pulley towards cockpit then slip the belt off of the top idler pulley

here it is

you need to take the tension off the belt by pressing on the automatic tensioner pulley. once the tension is off the belt can be removed. the new one goes on in reverse. The new one might seem very tight. Wrap the belt around the hardest pulley(s) first

if the old belt is still on, its quicker if you just trace how the belt goes around the different pullies on a piece of paper, or take a digital photo of the belt. that way you how to install the new one.

You need a 14mm socket on a extended breaker bar,
place on automatic tensioner center pulley bolt which is the dumpy pulley located above the alternator.
Move the nut to tighten which will move spring loaded tensioner to low side which will allow you to slip belt off.....installlation is the reverse

It is a safe bet the serpantine belt that drives the power steering and alternator has snapped, open the hood and check, there should be a belt about an inch wide or so running round the pulleys, if you can see a bunch of polished rings across the pulleys then the belts gone, you need a special tool or a decent toolbox to fit a new one, it often also runs the water pump so dont drive far.

the serp belt tensioner is a 12mm or 13 mm bolt that your loosen and move the alternator forward to slack the belt

Here's a link to the diagram you've requested. Best of luck.

you shouldent need to remove anything to replace or tighten your serpantine belt there is two pullys without grooves the one on the left should be the tensioner if you turn the bolt clockwise it looses the belt off so you can pull it off if done right you can take the belt and pull it around the fan then reverse to put a new one back on
