You will be able to change the belt by removing the fan shroud from the radiator, lay it over the fan. It can stay in the car. You should not have to remove the fan or fan clutch, unless you want too, but why would you want to do that. Loosen the tensioner as advised, you will then be able to remove the belt by taking it off the idler pulley, and follow with all the others. New belt should start on at the idler pulley and follow the routing diagram found in your owner's manual. Have a great day..

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
