Need to replace Serpentine belt and p/s belt on my 2002 honda odyssey is this complicated?

The procedure is as follows:-- You have to do it from underneath the vehicle. Take off the rivets to the two plastic covers, and then you will be able to see the tensioner for the belt. Use a 3/4 inch wrench on the tensioner (don't put it on the bolt that holds the tensioner on), and pull it toward the vehicle. The belt will loosen, and you can take it off. As a car owner, you know how important the belt tensioner is for your 2002 Honda Odyssey. However, internal parts wear and damage will loosen or seize the tensioner wheel, causing the belt to slip and make noise. Eventually, the belt may break, shut down the engine and lead you into a serious traffic accident. Before that happens, replace the tensioner on your Honda model and save yourself a lot of problems:---- Remove the Drive Belt:-- 1)Look for the drive belt routing diagram on your vehicle's engine compartment. This is a black and white label, about 4 by 6 inches, usually attached to the radiator shroud or near the strut towers inside the engine compartment. This diagram will be your guide when reinstalling the drive belt. If cannot find one, make a simple sketch on a piece of paper. 2) Insert a belt-tension release tool, or similar tool, into the auto-tensioner arm. 3)Rotate the auto-tensioner arm counterclockwise and slip the belt off the tensioner pulley. 4) Release the auto-tensioner but do not let it snap back in place. 5) Remove the drive belt from the engine compartment. Replace the Belt Tensioner 1) Unscrew the two auto-tensioner mounting bolts using a ratchet, ratchet extension and socket. Note the location of each bolt because they are of different size. 2) Remove the old auto-tensioner from the engine compartment. 3) Set the new auto-tensioner in place and start the two mounting bolts by hand. Make sure you install the bolts in their original place. 4) Start tightening the bolts until they hit the stop using the ratchet, ratchet extension and socket. 5) Torque the two bolts using a torque wrench. Torque the small bolt to 16-foot pounds [22 Nm] and the large bolt to 47-foot pounds [64 Nm]. This will help.
