On the belt routing diagram under the hood (near the grille, but under the hood) you will find the location of the 'tensioner' pulley. You need to get a 15mm socket and place it on the bolt on the tensioner pulley. Then use a ratchet to put clockwise pressure on the bolt to loosen the tension on the belt. This will allow you to remove the belt from the idler pulley, remove the bolt, put on the new pulley. Now put clockwise pressure on the tensioner pulley again to put slack in the belt so you can slip it around the new idler pulley. You're done.
Take the belt off, un-bolt the idler pulley, bolt the new pulley on, and finally put the belt back on and Viola!!
Are you talking about the "idler pulley"? They are quite simple to change. Loosen the serpentine belt by using a socket on the center of the tensioner pulley, slide the belt off the idler pulley, use a socket to pull the center bolt of the idler pulley and replace the pulley with a new one.

I assume you mean the idler pulley on your timing assembly, if this is the case then the belt is too tight loosen tensioner pulley. if you mean the automatic tensioner pulley for your alternator and A/C and the like, the you probably need a new tensioner] Good Luck
i dont really know-but to find out just look it up on google!
Remove belt and check to see that it rotates freely and smoothly

The idler pulley is attached by a 14mm hex head bolt. Although the pulley turns counter-clockwise, suggesting that the bolt might be left-handed threads, it is in fact right-handed. A 1/2" drive ratchet with a 14mm socket will loosen the bolt if turned in a counter-clockwise direction. Be sure and loosen the belt tensioner, located below the alternator, and loosen but not remove the other alternator bolts, prior to removing the idler pulley.
Using a 15mm wrench, turn the bolt in the center of the idler pulley clockwise to relieve tension and remove the belt.
take pressure off the belt by pulling back the spring tensioner. Remove old belt, put the new belt on all the pulleys but the idler pulley, pull the tensioner back slip belt on to idler, Look to make sure you have the belt on all pulleys good, your done.
Get a socket and a ratchet. Find out what socket fits the nut on the idler pulley. The whole idler arm should rotate counterclockwise. That'll relieve belt tension so you can replace the belt.
