Chirping 2007 Mustang V6

Hi,

I recently began hearing a chirping sound that only occurs upon acceleration, not so much during idle. It sounds very similar to crickets.

Anyway, you can hear the sound here:

It seems to be getting progressively worse. And, to make things even more interesting, I had my oil changed on FridayÖ Anyway, any ideas would be greatly appreciated.

During acceleration? Sounds like a belt squeal to me. Is it coming from the engine bay?

noises can be really tricky. that almost sounds like a pulley going bad. remove your belt and turn everything by hand to feel for anything tight or not turning freely. could be a host of things though, like the alternator, power steering pump or waterpump. could even be a bad belt. theres a gauge for belt stretch on the tensioner pulley. you`ll see a triangle, needs to be within the sqaure areas. you`ll see what i`m saying when you look at it good.

i had a similar noise for 3 yrs, sounded just like a powersteering whine, but only on startup and only when really cold temps in the winters. turned out to be the trans.

05 V6 auto,

Could be the idler pulley, to check to see if it's the belt you could spray water from a bottle mister while the engine is running.....if the noise goes away you probably from the problem.

Hey guys,

Thank you for the input. It would up being the harmonic balancer. The rubber was coming off of it, causing this horrible chirping sound. A buddy of my dad's cut me a deal on an actual Ford replacement, and I got a guy to do replacement for me, for 75 bucks. Running much better now.

I have a 07 with the Pony Package. Mine started doing the some thing this past spring. I believe the problem is the bushings on the sway bars and stablizer bars in the rear. I sprayed all the bushing with silicone and it went away. It's just starting to chirp again. I spoke to someone in my Mustang club and he had the same problem. He said Ford told him you couldn't just change the bushing, you have to buy new bars. he spent over $1000. Silicone is a lot cheaper!!!

Sounds like a pulley to me. Could also be the belt. Take the belt off and turn all the pulleys by hand and see if any of them make a noise. My alternator just started making a similar sound, I assume the bearings inside it are about done. Look at your belt and see how it looks. If you see any cracking or glazing replace it

Hmmm. I had a shop tell me it was the harmonic balancer as well, but when they went to replace it. They said it needed a ford only part to remove it. Did your guy have the same problem at all?Lollipop
