2001 Buick Century Repair Manual
KenF answered 7 months ago Autozone's web site has a repair guide section, believe it is based on their AllData subscription service for mechanics/shops, can be viewed for free once you register for their site. You can also try your library, some branches carry repair manuals in their science and technology section.

You can get lucky and find a repair manual at although your car might not be old enough. (I scored a 56 F100 manual from there.) You can also try the 'Auto Repair Reference Center' which many libraries subscribe to, but you'll need to get a login for it, currently they have a free trial:. My states library system (Ohio) is switching over to AutoMate, supposed to be more thorough, as an Ohio library card holder you would have access to it through OhioNET. Very likely your own state would have some similar setup with either ARRC or AutoMate. Finally, you know the old caveat, you get what you pay for, and a free repair guide may not be accurate enough for whatever you need it for, you can always subscribe online to Chiltons and Haynes and Mitchells, their online guides contain WAY more info and pics than the printed guides.
