Its quite easy open the center 14mm bolt at the center of the pulley and there is a long I think 12mm bolt to adjust/release belt tension. Autozone have some popular workshop manuals for free on line once you register (for free) on their website
and get an online repair manual subscription.
There are two companies that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have,much better than generic workshop manuals from parts stores and much cheaper than the factory manual try Alldata which is very easy to navigate or Mitchell on line and get an online repair manual subscription.
Several HUGE thank You for the info.Alternator belt was easy to replace,Other belt NOW will be as easy.
Again Thanks a TON.
