Belt Chirp
I searched and didn't really see anything like what I am experiencing. I have a 99 5.4 F150XLT 4X4 with a belt chirp that lasts for about the first 100-200 yards of driving after startup then it goes away. I bought the truck in April with 99,000 on it and it started doing this shortly after I got it. I changed the belt to a gator back, cleaned the pulleys and the chirp is still there. It's really not a big deal, just annoying and a little embarassing when leaving a crowded parking lot if you know what I mean. I was thinking it is probably the tensioner getting weak, but want to see what y'all have to say before I buy one.
Thanks,

I would say it's probably the tensioner. If you changed the belt, and it hasn't gotten better, the belt doesn't have the proper tension. Try deflecting the belt, and it shouldn't bow more than 1/2" at the most.
Hope this helps!

I'm having the same problem. It lasts about 100 yards and at first I thought it was a loose plug or a leaking exhaust gasket. It does it every time you start the engine, doesn't matter how warm the engine is.

How long has this been happening with yours and have you had any other problems, ie. cooling, charging, etc... I have no other problems with mine. I can start it, crank the wheel stop to stop with or w/o A/C and no chirp, but as soon as I put her in gear and hit the gas, wheels straight or turned, it chirps. It's just odd that I get no other noise from the belt after a hundred yards or so.

It started about 2 weeks ago and everything works fine. When I first heard it, it sounded like a spark plug wire that was loose, but then it would quit after 100 yards or so. I've been trying to pin point it by starting the engine and reving it via the throttle body with the hood open (I can hear it then). I would guess that we have two different sounds. It's interesting that they both go away after a few yards.

Replace the tensioner, and replace all the idler pulleys.
These are fairly cheap items, and even the aftermarket has them. What happens is grit gets in the pulleys and causes the bearings to trash themselves. I would pull the tensioner pulleys off first and just spin them by hand and see if they operate smoothly.
Also if you have dirty fluid in your powersteering fluid system it will squeek until it warms up. Flush and fill with merconIII and you will be all set. If your fluid is black its overdue for a change.
