Belt replacing how do you change the alternater belt

Hi most alternaters have free bolts,you have one that is to adjust and the other two to hold it firmly in place,one bekt and one electical plug,
so loosen the free bolts take belt off take electrical plug off the back of the alternater(sometimes there is a single wire as well) then take all bolts out remove alternater,put together in reverse,
put bolts in belt on and adjust so belt dose not slip,then do electric.
job done.hope this was some help.

If the alternator is on the top in the open, just loosen the alternator bolts a little bit. Then push the alternator to loosen the belt to remove it. Do the opposite to put the new belt on.

If the alternator is buried under a lot of other things, it's a lot tougher job.
Hope this helps.

What is a 306?

If the alternater light has come on in the car that means that the alternater is bad and you need to replace. You can also have it checked at your local auto parts store if you would like.

Good luck

There is a spring loaded tensioner on the belt line. You can put a wrrench or socket, usually 15mm, on the bolt and put pressure to turn the tensioner. Then carefully remove the belt from the pulley and gently allow the tensioner to release. When re-installing it. be very careful not to have your fingers under the belt, there is a large amount of pressure on the pulley.

THE ALTERNATER IS DEFECTIVE.
CHANGE THE ALTERNATER.--REMOVE THE SERPENTINE BELT BY PUSHING THE TENSIONER PULLEY WITH A CROW BAR OR BIG SCREWDRIVER. BE CAREFULL TO NOTE THE ROUTING OF THE BELT FIRST, THEN REMOVE THE ALTERNATER BOLTS. INSTALLATION IS THE REVERSE OF THE REMOVAL.

check the belt routing, you may have inadvertently routed it wrong, ive done it plenty of times on a taurus, think about it, if you didnt change the belt, how did it get longer????

My apologies for the delayed response. I am going back to answer unanswered questions.
1. Yes, you have to take the other belt off to take this belt off.
2. I use a wire brush to get melted rubber out of the grooves on pulleys with grooves. I use a wire brush then sand paper to remove melted rubber of smooth pulleys.
3. You should always replace both belts instead of just one.
