You need to replace the tensioner assembly, not just the pulley.....

Where is the tensioner pulley located on a 1994 pontiac bonneville? and how do I adjust it to get the alternator back on? Thanx


the tensioner is located directly below where the alternator bolts on. it is an automatic adjusting tensioner so you can't adjust it . you can only move the pulley back and forth to allow slack in the drive belt.

There is a tensioner pulley attached to an arm.
Release the tension on the belt by undoing the pulley arm bolt, the belt will have enough slack to slide off the pulleys.
To put it back on, you find the diagram on the radiator guard or under the hood.

How do I change a serpetine belt on a 1999 Pontiac Bonneville ?


be sure to view the belt diagrahm...locate the tensioner pulley and insert the drive end of your 3/8 drive ratchet into the square slot in the tensioner...move your ratchet clockwise, you should see the belt loosen...then lift off, when replacing with the new belt...install over pulleys...you will need to twist the tensioner pulley with the ratchet to install over the final pulley...release and belt should remain tight...again check the belt diagrahm for belt accuracy before test running...:)

A pulley appears to be coming off of my 99 pontiac grand am causing a squealing and knocking noise because its rubbing on a piece of metel


Sounds like a "tensioner" and or belt. The late 90's model Grand Ams & Grand Prixs were notorious for tensioner problems. You'll need a new tensioner first the a new surpentine belt. A belt that has worked GREAT for me is the auto after market product called a "Gator belt". It looks like an alligator's back on the inside as opposed to the stock belts which are ribbed on the inside. The after market people, (Auto Zone, Oreilly's etc...) can provide the correct Gator belt given you make, model and engine size.

It appears that either the new tensioner or some other pulley is NOT lined up properly. Check to make sure all pulleys are in alignment.

Thanx for diagram, where do i start on changing serp. belt on 1996 bonneville?


Crank the tensioner over so that you have some slack in the belt and pull the old one from one easily accessible pulley. Pull the belt off the pulley system and put the new one on following the diagram. Crank the tensioner again and use a screwdriver to pull the belt over the uppermost pulley. Release the tensioner and check belt tension.

Loud squealing sound in my engine


Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.

If the belt broke check the area around the belt for any damaged wiring, look down by the crankshaft pulley.
