Because serpentine belts use a spring loaded tensioner for adjustment, belt replacement tends to be somewhat easier than it used to be on engines where accessories were pivoted and bolted in place for tension adjustment. Basically, all belt replacement involves is to pivot the tensioner to loosen the belt, then slide the belt off of the pulleys. For tensioners equipped with a 1⁄2 in. (13mm) square hole, insert the drive end of a large breaker bar into the hole. Use the breaker bar to pivot the tensioner away from the drive belt. For tensioners not equipped with this hole, use the proper-sized socket and breaker bar (or a large handled wrench) on the tensioner idler pulley center bolt to pivot the tensioner away from the belt. This will loosen the belt sufficiently that it can be pulled off of one or more of the pulleys. It is usually easiest to carefully pull the belt out from underneath the tensioner pulley itself. Once the belt is off one of the pulleys, gently pivot the tensioner back into position. DO NOT allow the tensioner to snap back, as this could damage the tensioner's internal parts. Now finish removing the belt from the other pulleys and remove it from the engine
You don't, it has a spring loaded tensioner, If the serpentine belt is loose the tensioner has failed and needs to be replaced

About 20 minutes
I have a diagram based on my own Corolla with single belt, but I have nowhere to post it.
which pully do i remove tension to remove the alternator?
Take it to the dealer
The way I understand it is I'm not supposed to put a link here. So any parts house will have one, you can go to the library and use the Haynes, Motor, Chilton book, or Google these words "serpentine belt routing diagram Toyota Corolla 2005", or " serpentine belt routing Toyota 1ZZ FE" ..either will work, then when the page appears click 'images' on top
loosen the one or two bolts holding the alternator in place, i believe 14mm, then loosen the 12mm on the adjuster (side) and "screw" the 12mm bolt down to lower the alternator down enough and replace the belt. This is almost the same for every Toyota engine which doesnt use an automatic belt tensioner (serpentine) on the alternator.
So I can put the belt back on the car there are no diagrams on the to show me how it go's on.
