The fan in no way needs to come off or be messed with to remove/replace the belt. I don't understand why it even gets mentioned.
Just insert a 1/2 drive ratchet or breaker bar into the square hole on the tensioner and pull towards the passenger side (5.4) to release the tension. Slide the belt off the alternator and then you can let all the pressure off the tensioner, SLOWLY. Then work the belt off each pulley. Reverse the process to install the new belt.
I changed my serpentine belt last night. I have 76,000 miles on my truck and put on a Gatorback belt. My old belt squealed when shifting hard. After taking off the old belt, I could see the metal in the belt, it had some horizontal cracks in the grooves, and the back of the belt was pretty glazed over. Now I have no belt squeal at all.
This thread was a great help in changing my serpentine belt. Thank you everyone! It took me about 30 minutes to change the belt. It took me about 10 minutes of looking over everything first, so approximately 20 minutes to put the belt on.
I would like to add a few things to these directions. First is to make sure you turn the tensioner clockwise. Also, I only have a 16" breaker bar, so I used the closed end of a 7/8" wrench on the end of my breaker bar for an extension and more leverage. Finally, a 24" screwdriver to guide the belt onto the hard to reach pulleys came in handy. My forearms are too thick to get into some of those places and this helped out a lot, especially around the A/C pulley.
finally got around to doing it. been dreading it for a while. it's actually really simple. bought a breaker bar at harbor freight. removed the intake tube- one screw. turned the tensioner. removed belt. installed belt. checked to see if it was lined up right. everything good. test drive, no problems so far. the belt was brittle and cracked on the grooves and shiney as well. 132k miles on the clock. saved myself 150 bucks.

One thing to keep a close eye on are the two idler pulleys and tensioner pulley. They are prone to bearing failure, keep a close eye for what would appear as rubber build up on the pulley surfaces, you could have a bearing dragging.
Idler #5 was the problem....new one was not that tight on the shaft, I was
surprised. I would expect them to be tight. I torqued it down to 18ft/lbs
put the belt back on (AC compressor was a PITA) but 10 minutes and it was
Yeah, its a pretty easy job to tackle by yourself (I've done it several times doing manifold work and supercharger install). Just make sure you get the belt completely set in all the pulleys or it will lead to you destroying the belt. Ask me how I know. Pulley 5 is where it is handy to have a buddy on top holding things while you get the belt in the grooves.
