Tools to use?

2000 cadillac deville..what tools do I use to remove the pulley and the tensioner to change the belt? Can I do it myself or have a mechanic to do it for me? Estimate on time as well thanks

Use a breaker bar to pull the tensioner arm back and you should get more than enough slack to remove the belt and get the new one in place. If all goes well a new serpentine belt is less than an hour of work, 15 minutes if nothing's in the way of the belt path. You shouldn't need to remove any idler pulleys unless they are worn, and the same goes for the tensioner.
