Well guys and gals I have another question for yall. I recently went down a dirt/mud road and mud got all over my truck and a little muddy water splashed into my engine compartment. I didn't think anything of it, because the engine bay has gotten wet before with no problems. But anyways, I was driving home from work on the same day I went down this road, and this was probably 4 hours after I did it. So the belt started squeaking, I was like oh great. So when I got to the car wash I opened my hood and just rinsed off the mud. And it was still squeaking a little bit. When I finally got home, I used an old candle and put some wax on the belt. This stopped the squeaking. But I also noticed that the engine bay was still dirty. So I got some soap and water and scrubed it down. I didn't use high pressure water, it was simply from a garden hose to rinse it this time. But when I started my truck when I was done it wasn't squeaking or anything but I let it run for about 5 minutes and I started to hear a high pitch whine. I opened the hood and its not the belt itself (well I guess it could be) but it sounds like it's coming from one of the pulleys or maybe a bearing or something. Any ideas? It's a 2002 3.0L V6.

 

Mud in the alternator?

 

You think that would do it? And could I just spray the alternator with water to get out the mud if thats the case? And FoMoCoEdge are you really banned, because you can't post if you're banned correct?

 

Wax on belt = no good.. you simply make it slip smoother reducing the noise.

Its possibly the idler pulley If I remember right there are a large number of repairs on that for your engine. Also alot of people switched to the
goodyear "gatorback" belt.

i hear one too every time i floor it.

 

me too. but mine is my wife, HAHAHAHAHAHAHHAHAHA

 

Is it a constant whine or a squeak type noise coming from one of the pulleys. Mine has been squeaking ever since I went off road the first time, I think water gets in one of the bushings/bearings and makes the noise. I always have my stereo up enough not to hear the squeak so I haven't done anything about it yet.
I have a 4.0L but my friend has a 3.0 and it does the same thing.

 

My ideler pulley squeels sometimes when it gets dirty OR... Might be the prob. It always stopped after I hosed it off and let it dry out.

 

Hmm well then I'm going to guess that it's the idler pulley and also the belt is squeaking again, how can I stop that?

 

new belt...its probly your idler pully or belt tensioner pully

 

How much will a new belt cost? Before I got my truck the dealer owned it and it was a loaner vehicle. And I think around 26k miles they replaced the belt. Could it be more than just the belt? Because two belts in 42k miles seems excessive. And as far as replacing the idler or belt tensioner how much would parts cost?

 

pully's are really cheap my belt for my truck was aroun $30...

 

Ok just looked at Autozone, 36.99 for a Goodyear Gatorback belt. Should I spend the money or just get a regular OEM belt?

 

Mine started to whine and it turned out to be a sezed fan clutch

 

dont get a new belt that happend to me it lasted about a month n it just went away
