Hey guys I noticed one of my belts making a small squeaking sound in the mornings when I start it up and it continues even when it's driving. It's not a big sound it's really small but I notice it when I am driving with my windows downs close to a wall etc.. Which belt do you guys think needs replacing? Coming up on 59k miles. Thanks.

 

I'm betting it's not the belt, the belts are pretty stout and with only 59K doubt highly it is that stretched. My '08 explorer had this same issue brought it to ford since it was still under warranty, my tensioner was no good. The spring that is inside the tensioner wasn't up to par and was allow the belt to slip. they repalced the tensioner & belt and all is good, also some tensioner will bind and slack off and spring back( this is in simple terms) so even though it looks like there is tension sometimes it isn't enough. on a slimer chance it could be a bad pulley something like an idler. check it out further but if the tensioner is going bad a new belt will slip and get wrecked again.

 

Cool ill tell them to check for that thanks

 

Easy test. Spray some wd40 on the belt while it is running. If the squeek stops tell me And ill show you a free way to stop it.

 

Hey 2006 mustang gt,

Have you brought this up to your Ford dealer’s attention? If not, please make an appointment with them as soon as possible. Your Service Manager is in the best position to look into this for you. He can also look into any warranty, Recalls, or Customer Satisfaction Programs that may apply to your vehicle. If you need further assistance, do not hesitate to PM me.

My DD Milan had a similar squeak.

First the belt tensioner was replaced. Still squeaked.
Then they replaced the water pump. Squeak gone.

 

Good advice. I've changed my alternator and tension pulley. Sounds like water pump is next. Thanks.

 

I believe I'm having this issue & I honestly think its my alternator. I'm not gonna spend 200 to replace my alternator tho over just a squeak :\
I don't suppose there are any other suggestions?

 

Well if anyone cares I asked a friend at the tire shop down the road from me & he pointed out the idler pulley was more than likely it. I swapped it and no squeak!! Dealt with that crap all winter!

 

I was gonna suggest just taking it off, cleaning and reinstalling the idler. Was it damaged?

 

It had a little play & it looked worn towards the back side of it along with the belt looking warn. Belts only a week or two old

 

Do you have under drive or stock pullies?

 

Engine wise everything's basically stock

 

Well it got down to 40ish and now the squeal is back :\ apparently it's not the idler pulley :\

 

Try the wd 40 to isolate what pulley it is. Any surface rust on the other pulleys?

 

Pretty sure no rust. It's been a DD the last 2 years. & the last time I sprayed wd40 under the hood it made a mess plus made it worse :\

 

DO NOT spray any more WD40 on the belt. Go to the parts store and buy some valve grind compound. Comes in a tube from permatex. When the engine is OFF, dab some of the compound on your finger, wipe it on both the smooth side of the belt and in the ribs of the belt. What it will do is polish the surface of your pulleys. When many cars get old, they develop slight corrosion on the pulley grooves, resulting in a constant noise. It's a temporary fix, only other thing you can do is replace all the pulleys. Let me know how you make out!

 

I think it's my water pump

 

I had the same issue on my Miata. Water pump was it.

 

When I get cleared of fixing my pops truck I broke I'm probably going to get a new one
