Yeah i have a feeling that could be it i mean when the truck is running it seems like the idler puller is kind of wobbing, do you think i should replace that or maybe tighten it up if possible?

Does it look wet or oily? If it does change it. If you dont remember the last time your belts have been changed its usually time to replace them. they are not expensive and its nice to have a squeak free engine.

I have the same problem. I replaced the idler pully, tensioner pully, powersteereing pump pully and it's still squeeking. It goes away for a while when I spray it down with Liquid Wrench. But I think the problem is the water pump pully. I have plans to change it too.

If the sound goes away when you spray the belt then it is most likely the belt.

Default Re: Have a belt question

I recently bought a 99' 2WD ext cab ranger with the 3.0. I encountered the squeaky belt soon after buying it. Here is what I did to fix it:

1: replaced belt with a Duralast belt from autozone. (Still squeaking)

2: Spray the new belt with belt dressing. (Quit squeaking for a few minutes then the squeak became worse than before spraying belt dressing)

3: Removed the belt cleaned the belt with mineral spirits and then washed with soap and water. Cleaned pulleys with mineral spririts and a brush, then rinsed them with accetone. reinstalled Duralast belt. (still squeaking)

4: Replaced idler and tensioner pulleys. Reinstalled Duralast belt (They needed replaced anyway but still squeaking)

5: cleaned pulleys with a die grinder and a wire wheel. Reinstalled Duralast belt (still squeaking)

6: Replaced the Duralast belt with a Dayco belt from Autozone. (Have driven approximately 400miles no squeak so far)

I'm definately gonna get a dayco belt on order tonight. Thanks man! It didn't even dawn on me that it could be the brand of belt that's making that annoying freakin squeek.

I disagree, my water pump got all screwed up when I put my flex fan on with out the spacer. I would spray the belt and the squeek went away, upon further inspection I noticed the belt moving front and back while look head on at the belt from the drivers side fender. I thought that if the bearing went on the pump it would leak.... not the case here. I replaced the pump and installed the spacer to make sure everything was centered, no more squeek.

To the OP, spray some lube on the backside of the idler and tension pulleys, try to get on the bearing and none on the belt, if the squeek goes away then they need to be replaced. Do one at a time as to single out which one it is. If the squeek is still there after lubbing the bearings, then I would say water pump.

yeah, I have so far replaced the tensioner pulley, idler pulley, power steering pulley and the belt 3 times. I replaced the belt every time I replaced a pulley trying to eliminate possibilities. I am planning on replacing the water pump but I haven't got the pulley for it yet. But I have the new belt on order. I'm definately going with Dayco this time. Thanks guys!

I don't know about the smaller motor, but the 4.0 is notorious for the crank shaft pulley separating from the rubber center. You really want to check it out because as it separates, you run a risk of damaging your crankshaft position sensor. It will do exactly as you are describing. It happened on mine... I was trying to figure out the belt squeak and tried soap, spray, etc. I looked down over my pulleys and saw that the crankshaft pulley looked to have two stages. Come to find out, it separated and the rubber in the middle of the pulley was what was squeaking.

Here is what mine looked like (this is not my photo, this was from a very upset Explorer owner)....

Looks like you have thrown enough money at it, maybe a good time for a mechanic to check it out. There is a way to isolate engine sounds. You can use a stethoscope or a small hose in your ear. I chased a squealing belt around for about a month.

Then I took some time and examined the pulleys when loose (no belt) and I cleaned a few of them up. The belt was good and I took care to get it on right. I was about to go after the water pump but there was no tell tale leaking from the little leak hole. I put the belt back on again and checked placement again to ensure all ribs on all pulleys were on corrrectly.

Started up and same thing again. After I threw my wrench in the yard, I got a hose, cut it, and used it as a stethoscope of sorts. It was the darn Alternator bearing. Imagine how much time we could save if we go in for a check at a good garage. I kick myself everytime I do that.

The Dayco Belt is still doing well even in the cold winter days.
