How do you replace an idler pulley on a 2004 Ford F-150 5.4ltr?

The 2004, Ford F150 5.4 ltr has three idler pulleys that are easily identifiable as they only contact the belt over a very small arc of the wheel. The replacement procedure is basically the same once you have identified the candidate idler. Be sure to match the part at the auto supply store.
This procedure
1) Rotate the tensioner clockwise and remove the belt. Use a 1/2" wrench directly into the square hole and a cheater pipe is helpful so one hand can loosen while the other hand removes the belt at the generator.
2) Remove the candidate pulley.
3) To install, reverse the procedure. All pulleys have 18 ft-lb torque.
4) be absolutely sure the belt is properly aligned on all NINE pulleys before starting the engine.
P.S. - This a great time to inspect the belt and consider replacement. If over 100,000 miles change the belt unless it looks absolutely perfect!

loosen the nut on the idler pulley. There is a bolt at 10:00 o'clock from the pulley. Loosen this bolt until you can put the belt on then tighten the bolt till the belt is tight then tighten the nut on the idler pulley. Recheck the belt tension after a day or so..

How do you loosen the belt to install a new alternator on a 1996 Chevy Cavalier?
On my 97 Cavalier I can use a 15mm box end wrench on the spring tension idler pulley. The idler pulley is in the middle of all the pulleys on the belt. It is right under the engine mount and above the crankshaft pulley. It is difficult to get to, but I can put the wrench on the bolt in the center of the pulley and apply clockwise force (looking at the engine from the passenger side fender) to rotate the idler down. This will loosen the belt. You will need to do the same to re-install the belt. Be careful, the pulley will try to spring up when you remove the belt. Make sure you memorize or draw the belt path before you remove it. If you forget, Advance Auto Parts can print a diagram. It was the same for our 2004 Cavalier. I took the right wheel off and lining behind it.... much much easier! (pulley and belt right there)
