Belt noise
Sorry it is not the same vehicle, but my 97 Explorer has noise that sounded like it was a belt, changed the Serp. belt. Noise is still there. Mechanic friend said if that didn't take care of the noise then it could be a pulley or pulley bearing going in the belt system.
First, determine if the noise is created by the belt or a pulley in the system.
Hope that helps

I've found that belt dressing works great, it also helps the ole belts last a bit longer, however it can get a bit tricky spraying the stuff on.
You can get it at any popular auto parts store.

I forget what kind of belts those have
but belt dressing is for v-belts only.
DO NOT USE belt dressing on any type of serp. belt
And use it very sparingly or it will build up and make it slip worse.

Do NOT use wax or any type of lubricant! Belt dressing is a stopgap even on V-Belts.

You obviously don't know what Skate wax is. It's not polish, it's preaty much candle wax only harder.

Yeah I know what it is, don't use it on a serpentine belt. It may mask the problem for a while but it will make it just that much harder to fix it right when the time comes. It also reduces the efficiency of the drive system thru slippage, costs fuel mileage (small) thru increased belt temperature, which shortens belt life... Bad medicine!
That chirp and/or squeal is from a slipping belt. Putting a lubricant or wax (skate or other) just makes it slip worse and shifts the squeal up into the ultrasonic range so you can't hear it.

this probably is the question that should have been asked first...
What kind of mileage is on this motor?
If there was a pulley that I'd check out first it would be the tensioner pulley and spring.

Belt noise
Usually a bad bearing will growl, grumble, rumble, grind, or howl, and it will usually do it all the time cold or hot. You can usually hear it or even feel it. You can use a rod, stethoscope, or wooden yardstick to conduct the vibrations to your cheek bone or ear. A belt slipping will squeal or slip worse when it is cold and also when the engine is revved up or the alternator/AC/PS is taking more power to turn. If you are getting a squeal all the time the belt is shot and the pulleys are glazed. If a belt gets to the squealing stage replacing it will not permanently solve the problem. That is why you replace the belt as a regular maintenance item at the recommended intervals.

Belt noise
I didn't mean to start a rucuss with the skate wax, but its a old trick from way back that works. But lets talk about belts, serp or other wise for a sec. Why are there rubber belts on the front of my engine...hmmmm... why aren't there chains or gears, or even gear groves in the belts...hmmmm.... could it be because they are designed to "slip" under spike loads. If they didn't we'd all be replacing them every couple of days. So your squeal could be (like all strange sounds your truck makes) some magor problem ready to blow up in your face, or it could be your belt is too tight (gotta have some play for slipage), or it could be that your belt has had something splashed on it (antifreze, fuel etc) that dried it out a bit. So a little WAX would save you some bucks and get you another 20k out of the belt. Of course you should replace it at X number of miles etc, etc. But if we all did what we should do, we'd carry our stuff to a trained mechanic. Course if we did that this board wouldn't exsist, and then where would we argue about wax n such......

I am a Mechanical Engineer that has spent years designing V-Belt drives, timing belt drives, chain drives, and other exotic drive systems with many types of drive materials. If you want to use wax on your belt go ahead. I am just telling you from a Professional point of view that it is a bad thing. I hope the person that needed the help will check with some other professionals b4 he puts wax on his belt.

Well lets see, B4 I became a Mechanical Engineer I was a chemist (switched majors)... Will that do?... -hehe I put that chemistry to good use with some of those exotic drive materials, various rubbers, fibers, silicones, plastics, and urethanes, even some ceramic materials for drive surfaces. I didn't get much into gear drive design tho except for some light duty applications and controls. Later on I was involved in electronic servo drives, electronic controls, process controls, hydraulics, and even designed industrial computers both hardware and software since b4 the PC. That makes me ancient. The chemistry again came in handy with the materials used in electronics manufacturing processes and assembly. Seriously tho, don't put that wax on a drive belt, it only masks a problem and creates more.
-Sorry
Mauser's only solution is to replace that belt and hope the new one does not develop any noise. If it does he will need to resurface his drive pulleys and put on another fresh belt.
