Cold Belt Noise

Does anyone experience belt squeak when starting a cold engine? Mine makes quite a bit of noise until warm, then not a peep!!:o

What belt are you running?

Is it humid?

How much slack is in your belt?

We would see it at the dealer. Ford makes a "Rubber suspension isolation compound" or some crap. It is a clear gel and STICKY. Engine off, one 3/8 daub spread across the ribs and another on the smooth side. It works VERY well at eliminating NVH.

I apologize for having no part number at all, but that name is close... LOL.

Mine does that. However the chirping is from the alternator bearing. Took me a while to figure that one out. Pissed me off to. It started with 42k on the truck.

Never put belt dressing on a belt. Ruins the belt and the pullies and it a PITA to remove. A belt squeel on start up is because of a loose belt over an alternator. A bearing will make noise all the time from my experience.

It's the NAPA belt that came with the upgrade kit. I'm pretty sure there is not that much slack, putting the belt on is almost impossible.

I heard the NAPA belts are notorious for noise, so I just got a Dayco on the recommendation of someone who deals with these belts regularly and has dropped the NAPA belts due to the number of return customers complaining of belt noise. I will be putting it on, and will let you know in the morning.

The noise goes away when warm, so not sure about the alternator, but who knows; the alternator did come with the blower and I used it instead of my original one.

Not this one lol. Took the belt off and spun the alt by hand and could hear it. It will do it for about the first 3 mins of run time. Longer when it was cold out. I sprayed some Teflon lubricant on the bearing and it stopped for about a week. And yes belt dressings are bad news.

Gates green stripe belts are the preferred belt of blowers.

Dayco's in the blower community are known as the worst...

GREAT~!!!

Well, turns out, Jason was right; it's my alternator. I went to change out the belt this morning and when I spun the alternator, I heard the "squeak". I'm in the process of putting my original alternator back on now. I guess I'll leave the NAPA belt on in light of the above.

How did your school car show go? I know you're busy, but when you get a chance...

Just a meeting last night, got the t-shirts for the participants and trying to help everyone get organized.... The biggest problem is the lack of volunteers from parents and students.

I should be free all, ill give you a call.

I know that, IT SLIPS. I did NOT say belt dressing. I said FORD rubber suspension isolator. It grips, then eliminates the belt. Plus it's waterproof. If the squeal goes away, normally the belt is glazed/stretched. If not, then you can use a stethescope or screwdriver to check all accessories to locate the squeak/chirp.

It's not a fix, it's a test.

Well, the chirp is still there with the original alternator, but it not as bad/loud. I put the NAPA belt back on, but will getting a Green Stripe soon; off to the tuner now.
