Changed my belt last night.

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.
