I think your best bet would be to get a haynes manual for gm cars. i just got one for my lesabre to do some work on it and it has great detailed instructions and wonderful pictures and diagrams. u can order them online. just go to and select your car

How to put serpentine belt back on

There should be a label under the hood that shows the pattern and You Tube has lots of videos by brand and year that show the actual process. Process if done correctly is to hold the spring loaded auto belt tension unit back (mine you just insert the head of a 3/8 ratchet and pull it back, move the belt into position and back the tension off, smooth on belt to smooth on pulley and grooved part of belt to groved parts on the other pulley.

Try You Tube first and you will get the idea, easier with a second person to help, I recently did mine alone outside with a temperature of 14 degrees.

If the belt came off for no reason inspect the tension unit.

I need a routing diagram for a 1999 Buick Century. and does it have a tensioner?

all cars that have a serpentine belt have tensioners the belt routing should be on a sticker on the cover or metal bar above the radiator,sometimes they have put on a belt cover at the front upper pulley showing the routing.if it is missing you can go to a parts store or a the dealer to look at the routing of the belt,better yet if you draw the routing on a piece of paper before you take it off also works

How to change serpentine belt on 97 laSabre

On the underside of the hood or on the radiator shroud there should be a decal showing the routing of the belt for the engine that came in the car. The tensioner pulley (should be designated on the decal) will need to be moved to remove the old one and to reinstall the new.

How do i change the serpentine belt on my 1999 chevy tracker

First, keep this diagram around as you will need it to route the serpentine belt when you reinstall it. There may also be a diagram under the hood by the radiator.

Diagram for 1998 buick lasabre serpentine belt

I found the diagram in my owner's manual.
I replaced the belt on mine just 2 days ago. All you need to do is remove one bolt from the lower motor mount and remove the spacer. After you relieve the belt tensioner, the belt will slip right through the gap. Don't forget to support the engine before removing the bolt. As a backup I took a photo of the belt with my digital camera beforehand... just in case.

Serpentine Belt

Generally there is a sticker under the hood, showing belt routing. If not, get a cheap (usually under $20) manual... not only will you learn belt routing, but tips on tensioner adjustment, necessary to replace belt. Even a cheap manual includes lots of stuff you may need to know in the future!
