You can probably changed it without pictures. You can take the serpentine belt off, and to do that you actually turn that tensioner that you want to replace, which releases the tension on the Belt. Once you have the belt off there is one bolt to take off the tensioner arm. It all comes off in one unit, and the new one will come already assembled, with a new bolt, ready to disc boat right in. There was a little pain that needs to line up to make sure you get it in the right position, other than that there's nothing to it.

SOURCE: how to change the rear 3 spark plugs on a Buick regal LS 2002

You can try rotating the spark plug boot a little bit-not even a 1/4 turn-to break the seal between the plugand the boot. Then pull the boot wire off with a pliers on the metal boot shield. Once the boot has beet rotated on the plug, the shield helps to remove it.

SOURCE: how to remove belt tensioner on a 2002 buick regal l s 3.8l

disconnect battery first, unbolt alternator(3 bolts), cross bar bracket(2 nuts) unhook both heater hoses out of the connectors(each has a 7mm head bolt in them, then twist loose), remove belt, then there are 3 bolts holding it on the motor, has a plastic elbow to the intake and an o-ring seal male port that goes into the timing cover. gently pry back and forth to work it loose so not to break either the elbow or the port off. alot of times it seizes up in there. the elbow is a hat trick to get in and out also, just be patient and take your time

How to replace serpentine belt to alternator


You'd better hope you have a belt routing picture under the hood. Usually the belt is released at the tensioner pulley, which is spring loaded to keep the belt tight. The pulley is unloaded by using a 3/8 long handled socket wrench. Find the square hole.

I have a 95 Buick Regal.It makes a noise when running ,but if take the belt off it stops.


it depends what kind of noise, if its a licking noise the pulleys that the belt is being turned by could be bad (belt tensioner pulley ,Idler pulley etc.) if its a squealing sound like a high pitched whistle or like a rubber heal screeching on a tile floor constantly the belt is no good there is fabric on the inside of the belt and when it wears away you will get the chirp or squealing /screeching sound from this. inspection of that belt will tell you look at the grooves if looks like shiny rubber you found it if it doesn't and the fabric is there then a pulley is the problem bad bearing can make the belt slip resulting in the squealing good luck LATER MAN!

High pitched sound just started. It goes REEEEEE!!


It sounds like your power steering pump as you said, but I would start with changing the main drive belt. I have come across this same problem before. If you change out the belt and you still have this problem, remove the belt and start the engine. Turn the wheels left and right and listen for the noise. If the noise is gone then put the belt back on and check again. If the noise comes back then you have a component problem. I have seen the belt tensioner to make noises as you describe. I hope this helps you. Let me know if this is helpful to you.
