Chances are the belt and tensioner is not the problem. Your water pump is. Check the bottom of the water pump and see if there is some anti-freeze comming from the weep hole. If there is then that is the problem. Anti-freeze will cause a serpentine belt to come off because of its lubricating properties If there are not leaking fluids dripping on the belt that would cause it to come off then, it sounds like a belt alignment problem. You should check your mechanics guide to determine how to adjust the alignment.

Where is the serpentine belt adjuster located on a 95 Chevy Lumina?

On vehicles with a single serpentine belt, tension is usually self-adjusted automatically via a spring loaded tensioner. No additional adjustment is necessary. If the belt is slipping or loose, then it needs replacing. Also check the tensioner bearings and replace the tensioner if necessary.

Is there a tensioner to adjust a squealing Serpentine belt on 2004 Taurus?

There is also a possibility that an idler bearing has failed but that noise is a bit different from a rubber on metal squealling noise. To be certain of the problem befor you start throwing parts at it is to remove the belt and check each pulley and idler pulley (on the tensioner) for excessive play and/or rough or lumpy feel when you rotate them by hand.

What is the purpose of the belt tensioner on a Saturn sl1 y?

The tensioner maintains proper tension on the serpentine belt. Too much tension can cause premature failure of the belt, water pump, AC compressor, alternator, power steering... Too little tension can cause belt slipping, resulting in premature belt failure and poor operation of the water pump, AC compressor, alternator... AND when those pulleys are slipping, they generate a lot of heat which can cause premature failure of the water pump... you get the idea.

Does the idler pulley cause rough idling?

No. The idler pulley only maintains tension on the serpentine belt. A faulty idler pulley can cause noise and a loose tensioner arm can cause belt slipping but other than having a similar name, it has nothing in common with engine idling.

Why would the serpentine belt on a 1994 Le Baron keep slipping off of the pulleys?

Assuming the tensioner is keeping the belt tight, you need to make sure all of the pulleys are still in a straight line. If a bearing has failed in a pulley the puley will "lean" causing the belt to run off the edge.

How do you replace the serpentine belt on a 2002 Dodge Caravan 3.8 V6?

Sears Hardware sells a nice tool which you can use to rotate the belt tensioner. It is essentially a long socket wrench with several shallow adaptors. I presume you should be able to get something similar at any auto parts store. If you don't have a copy of the Haynes Repair Manual, I recommend getting it. It has a nice diagram of the belt layout. Regarding the belt, when mine slipped off, I replaced the tensioner and belt, but it kept slipping off. I bought a Gates Serpentine Belt Drive Component Kit and it never happened again. Amazon sells it. Changing the tensioner is tough. The nut holding it in can be reached from below.

Remove serpentine belt 1995 Buick Lesabre?

Use a wrench on the belt tensioner. If there is a square hole, use the socket handle only, if not, use a socket the size of the bolt in the center of the tensioner pulley. Use only enough torque on the tensioner to release tension and slip the belt off of one of the pulleys. (You don't want to loosen the bolt, you only want to move the tensioner.) You did not ask this, but it is important. Pay attention to the routing of the belt. When reinstalling, make sure the grooves are centered and seated on all the pulleys BEFORE slipping the belt over the last pulley. (Of course, using the wrench to move the tensioner.) This can be tricky. You only get one chance, because if you crank the engine with the belt not correctly seated, you will be buying a new belt, and you could get hurt.
