Ford Explorer Squeaking/Whistling Belts Sign In

Hello everyone, here are my details of my vehicle:

2001 Ford Explorer Sport 2DR
4.0 V6
86,605 miles

Recently I've been noticing that my belts or something under the hood of my car has been making a squeaking/whistling noise. I've owned my car for sometime now so I am aware of the noises it makes; before it only made a squeaking noise when it rained (I guess the belts would get wet or something) but after a day or so the noise would stop. However about a month or two ago the noise began to become a permanent thing. I’m really not sure what is causing this but it seems to be something with my belts. Also I’ve been noticing sometimes when driving, if I am pushing on the accelerator (not too hard but with a little force) the noise will stop but then when I slow down it comes back again. I am not the biggest fan of Ford but hey it’s the best I could do for a vehicle, I am just curious what is causing these noises with my car. I am due for an oil change relatively soon so I am going to ask my mechanic to check everything out but I would like to know what is wrong prior to me getting it repaired.

I appreciate anyone who can give me advice.

SUV; It 'sounds' like a belt. Especially when you mentioned it was worse when raining. The only thing puzzling me is that it goes away under acceleration. Hmmmm. Have your mechanic check the belt, of course, but also the idler and tensioner pulleys. He can also remove the belt, start the engine, and listen for any internal noises. He can check the pulleys, also, while he has the belt off. If this is the original belt, I'd plan on replacing it, regardless.

Unfortunately, I am not the best with car repairs so bear with me. Anyways I know that a car has several belts, however I am curious as to which one in your opinion may be making this noise. I've popped the hood and listened but really couldn't conclude which belt was making the noise (they all seem tight and normal). If I accelerate slowly the noise will get faster and faster and then disappears when I am pressing firmly on the gas petal (that is what gave me the conclusion that it was one of the belts). Hopefully it's nothing too serious and just a belt issue.

I'm pretty certain that you have only one belt that drives all of the accessories. It's called a serpentine belt. They can be a bit spendy as can be the labor, but you replace one instead of three or four on the older cars.
If you are feeling brave, you can get a spray bottle with water in it, start the engine, and spray water on the belt to see if you can duplicate or quieten the noise.

Butting in again! Common on some Fords or at least mine! Two tricks if the belt is ok and not a mechanical problem. Literally grease the belt with silicone grease - it will quickly wear in and be fine + won't slip. Stays quiet for longer with grease. Test with WD-40 and if that shuts it up at all the grease will last longer. MUST use rubber friendly silicone!

Belt may have stretched to limits or shinned up pulleys which are an expense to replace and shouldn't need to. Goodyear makes a "Quiet" belt called Gatorback I think that works very well but will stretch much sooner than a regular good quality belt.

This noisy belt thing is much exacerbated by high speed driving on salted wet roads here right after snow or ice and the salt applied and melts the road and still wet.

Again - if you request a "Quiet" belt and that is the only problem know that it won't last as long even if it looks good to the eye.

See if I can find a graphic.....



That one if it shows, (not that part # necessarily)

Just to add a little more to the confusion. There is a camshaft sensor and syncronizer(bottom half of distributor shaft) that can cause the squeak and squeal. You may want to remove the belt and see if it goes away. If it goes away, it is either a belt or pulley. If the noise stays, look at the cmp sensor or syncronizer.



Being way2old is why I need help from younger minds
