Brand new alternator and still squeaking

[bawazir]

Every time i start my car i hear hard squeaking from the alternator side, than it gose a way after the engine warms up?

today i got my brand new alternator from auto zone, car preformed good but i hear a hard same squeaking from my alternator pulley, after a good engine warm up it goes a way ??

dose any one knows what might be wrong ?

[babbage]

tensioner and/or belt

[2vmodular]

those squeaking noises can be troublesome to pinpoint. it's possible that your new alternator is noisy right out of the box, but i'd suspect some other component is causing noises for you. a good starting point is to try replacing the tensioner, idler pulleys, and accessory belt like babbage suggested.

[DOOM]

All eaton swaps do that! :P

[justbob]

Lol^^^^^^^^^^^!

Purchase a can of Permatex Belt Dressing & Conditioner. It quiets squeaking belts. After I burp the cooling system on my Marauder the belt starts to squeak due to some coolant drips. I use the Belt Dressing and the squeaking stops. Jim

[tbone]

Get a Goodyear Gatorback belt.

I tried the STP dressing made it worse and louder, well am going try to change the belt and see what happens :alone:

[ImpalaSlayer]

All eaton swaps do that! :P

that part of the swap is identical to the trilogy.

with that said mine squeeks too bazzel. its the ****in brushes on the reg. has nothing to do with any other component on the belt drive

did you spin the alt by hand before Bob put it on?

That tells you right there that it IS belt related.

[fastblackmerc]

Replace the idler, tensioner & use a Gatorback belt.

[Mr. Man]

Try a different brand of cheese:D

[RacerX]

Soak the belt in diesel for three hours... :D

[bawazir]

did you spin the alt by hand before Bob put it on?

yes it spin freely

NAPA belt .

[Kennyrauder]

It's the tensioner

Thanks Bob, so how u been?

[RacerX]

Just installed a brand new NAPA belt the noise went a way :D, thanks guys for all ur help
:D I told u. :D

[Zack]

You could have brake cleaned a rag and held it on the belt first. I had a NAPA belt on there. :rolleyes:

[bawazir]

thanks for the advice, I really hate Napa parts, but there were nice enough to switched my belt for free any way,

[RacerX]

Watch out, he'll do it while it's running and lose a few fingers! :D Maybe some bleach on it... Smoke show!

[Zack]

Watch out, he'll do it while it's running and lose a few fingers! :D

Thats the only easy way to clean it...when its running.

And WTF to not liking NAPA parts? They are the best Parts store on the planet.

[bawazir]

No no i am just saying there belt is *****y, I freaking wasted 200 on alternator thinking it was the problem :( any way problem solved

[RacerX]

Just return the alternator and put the original back on.

[bawazir]

Just return the alternator and put the original back on.

they took it as core charge :( any way i got alive time warranty

[fastblackmerc]

"Alive time warranty"....

Is that for as long as your alive?

[bawazir]

"Alive time warranty"....

Is that for as long as your alive?

What i mean to say life time 4m auto zone

[bawazir]

Damn that squweek came back!

Last time i have changed my brand new belt from NAPA and my brand new motorcraft alternator , and the sqweeek! came back from the same place by the alternator do u guys know what is it due>?

[NATEHAWK]

Are you S/C?

[burt ragio]

Clean belt soak in a pail of soapy water use scrub brush then rinse. Check all pulleys for play. Check on alignment. If noise still persist get louder mufflers.

[tbone]

Bawazir, GET THE GOODYEAR GATORBACK BELT!!!!!!!!!!!!!!

I had this problem and it has been gone for 2 years because I bought a GATORBACK BELT!!!!!!!!!!!!!

Me to. Out of all the cars that come through my garage, I just now had one that squealed on start up with a two month old gatorback that I installed. Luckily it was a manually adjusted car and not a tensioner, that way I could play around with it to make a final determination on it being the belt. I couldn't believe it had failed after all the installs that I have done only using gatorbacks. I had to switch that belt over to a dayco brand as autozone no longer carries gatorback.

[tbone]

Autozone doesn't carry Gatorback anymore? Who does? I was planning on getting one soon for my wife's Explorer.

[justbob]

I didn't even bother to check around. They quit stocking them last month at Autozone.

[fastblackmerc]

Got mine at NAPA.

[bawazir]

Do u guys have the part number for the Gatorback on my s/c

Bawazir use some C-4 and you will never hear a peep out of it again! :up:

What's the difference between the "(6-rib) for Trilogy" and the "(accessory belt) for Trilogy"? The accessory belt is 6 rib, isn't it? Which one would I get? (It's for a Trilogy setup obviously.)

Don't know... I don't have a Trilogy...........

Is there an accessory belt on a Trilogy setup?

[RR|Suki]

There is the belt like normal, and then there is a blower belt on the trilogy cars

[RF Overlord]

Trilogy uses an 8-rib belt for the blower drive and a 6-rib for the "accessory" drive. I don't have either number handy (at work) but I'm sure someone will chime in...

[NATEHAWK]

If you are still having squeaks and it sounds like it's coming from the alternator area it's the bearing on the pulley attach to the tensioner. You can't see it but it's behind there. The bearing is cheap someone on here can chime in on the part number for the bearing at Napa.

[RF Overlord]

Good catch, NATEHAWK.

The Blackbird made more of a "roaring" sound than a squeaking, and I thought it was just because the alternator was now turning backwards, but I ignored it for too long until that very bearing disintegrated and took the belt with it. I was very lucky there wasn't more damage.

Does anyone know the part number for the ribbed idler that replaces the smooth one on the passenger head? It was supplied with the Trilogy kit, but I think (hope) it has a Ford part number.

This what i have done 2 months ago:
1) i put in a new alternator & new alternator pully , still squweeking !

2) put a brand new tensioner located by alternator,, still squweeking!

3) CHANGED THE BELT FROM NAPA, SQUWEEK IS GONE

after a month and half sqweek from the alternator side came back, so what i have done is put a brand new alternator today and it became less ,should i buy a brand new gator belt, or i should i change every single pulley in the car ?

I'd go with the Gatorback belt. Also check that the pulleys are aligned.

Sell the car. It squeeks and gives you headaches.

If you just changed the belt in the first place, you would have alot more money in your pocket and some sanity left.

[MrBluGruv]

How common of a problem is pulley misalignment? I'm on my 3rd alternator since I've owned the car and this morning it JUST started making a bit of the chirping noise again, I'm beginning to wonder if one or more of the other pulleys aren't aligned properly.

If they are bolted into the cover properly there shouldn't be a problem at all with alignment.

[MrBluGruv]

Hmmm, the only other thing I can think of then is excessive moisture then somehow, but I don't know how it would be getting in/on the engine or alternator. Would that really even cause a problem?

Are you buying alternators from FORD or FLAPS?

Anything but OEM is GARBAGE

[MrBluGruv]

Well, of the three I had (first one was on the car and original), the second one I think was a remanufactured unit instead of truly new, and this one is new and Ford as far as I know of, both times I had them replaced by a shop so I have no idea, but the second one I had to buy was definately more expensive than the first.

In the future, after having changed the alternator on my friend's Mustang with him, I feel confident I can buy the part and put it on myself and save a bundle, probably better insurance I'm getting the real deal too.

[bawazir]

did you ever change the tensioner?

can tensioner make a squeak ??
and even thow Zack changed it with Eaton swap , it been only couple of months ,
is Eaton Tensioner part# same as the stock ones? dose any one have a part# that i could buy from napa or autozone? damn that **** getting louder :(, I just got my brand alternator this week , and its still f****ing squweek, please help ,, they dont sell gator belt at autozone so i just put NAPA brand ..,,
Noise still coming from the alternator side,,
:help: :help:

The NAPA near me carries the Gatorback belts.

Isn't justbob your mechanic? Have him fix it.

[Zack]

A Gatorback isnt going to fix the problem. When the problem is fixed, then the squeek will disappear.

[MrBluGruv]

I'm more curious now as to what could cause bearings in brand new alternators to start failing within weeks to a couple months of install, I'm tired of dropping a couple hundred bucks at a time to replace it ever 6 to 9 months. I'm still thinking maybe I'm getting too much moisture into the engine bay when I wash the car?

At any rate, I would think of the belt as the last possibility given it was the right size and not falling to pieces in the first place.

[Zack]

Sounds to me like you got oil or coolant on the belt at some point. You put a new belt on then it eventually absorbs the residual fluids on the idlers and other accessories.

Im pretty sure I told you to soak a rag in brake cleaner and find a somewhat safe place to hold the rag against the belt until all the crap is gone or evaporated.

Instead of taking a chance and possibly losing a finger or two (I have seen
that happen).

Take off the belt, clean both sides really good with brake cleaner, then clean each pulley with brake cleaner.

[badroadrunner]

Replace the tensioner, After you remove the old one look at the teflon inbetween the two pieces. You will see that the top is worn more than the bottom, this makes the tensioner sit at an angle causing your belt to drag slightly and squeek. The teflon is sandwiched between the stationery part that bolts to the block and the piece that pivots, use a ford part,

[bawazir]

just replaced the belt to deco autozone belt , and the noise is gone

He refused to take my advice on little things like sealing up the upper and lower (no screws or clips, nothing at all..) wiper tray to prevent fumes from entering the passenger compartment and kept coming over daily to have me look for other issues. Simple obvious things needs to be addressed first and he wasn't willing to take care of them. He has changed since then and is now tackling these easy fix's that need to be fixed anyways, he has even learned how to do some of his own work and actually enjoy it while saving money. I'll allways be here for any member, but I get very annoyed quickly when they won't listen to sound advice whether it be maintenance, or process of elimination.

Update on this thread...

The problem was the belt was routed incorrectly, which caused the smooth side to rub on one of the alt bracket support arms, also @ 98.5" belt was too short... With a 99.5" belt correctly routed, all issues are gone...

[Zack]

When I gave him the car back it had a 98.5" belt on it and it fit perfect with no noises.

The belt goes from the ribbed idler on the passenger side...OVER the first alternator bracket leg....around the alt. pulley.....down over the smooth idler...to the PS pump.

From all my experiences with these brackets a 99.5" is too long and will not provide adequate tension.

[FordNut]

My setup is kind of unique but I believe my K080980 belt is 98.0", one of the hard parts of the Eaton/Trilogy setup is having to remove the bracket to install the belt due to the belt routing over the top of one leg of the bracket.

[TFB]

Hi Zack

I went on the info from justbob that the brackets were same as the Triology set up and those use a 100" belt, he also stated that it appeared on his that if it were any longer the 100 would be too long... Sooo after we couldn't get the 98.5 belt on the tensioner pulley, we tried the 99.5 and it fits nicely with tensioner in it's mid travel...

Except of course for the relocated alt & added idler under it(Abdul's wrap bypassed this idler), I believe the wrap I'm using is identical to stock... Is that incorrect?

EDIT Possibly some of the idlers are now smaller than prior? I believe they've been changed since the original install...


Tom

[Zack]

I dont know what was changed since I handed the car over.

If it fits then its A-ok.

Tom

That explains the short lifetime... The accessory belt rarely fails on Eaton or Trilogy cars. Centrifugals and Kenne Bell, now that's a different story.

[justbob]

I was the very first to replace his Alt. and the idler pulley to quiet up a squeek from that area. I installed the original belt back with no issues at all. The squeek ended up coming back and he swapped the alt again, or twice, I don't even know, also a couple new belts since then. I think somewhere down the line of his dealing with a couple different part stores and their cheap azz alternators that they sold him the wrong belt and he misjudged direction when he installed....???

Either way, glad to hear it all worked out. Do you see any rub marks now after a few hundred miles?

[TFB]

Bob all is fine now with no sign of rubbing after 400 miles... I dunno what changed, but the 98.5" was short enough that even with tensioner at minimum, belt would not slip over the pulley(thinking the pulley under the alt may be larger than orig)... The guy at AZ who helped, had a tensioner tool so we had no problem compressing it... That lower pulley was bypassed and rub was on lower leg on the alt bracket...

BTW, the belt was on correctly other than issue already mentioned... At one point I thought it was flipped over, but that was apparently because I was looking at the slick side of the belt when it was laying on the W/P pulley, after it had broken...

[burt ragio]

After three alternators oem or aftermarket that tells me it's belt alignmemt. Weather it be a Gates or Gatorback makes little difference. Not having the belt wrapped can cause improper tension & lead to belt noise. But in the design of the alternator brackets two alternator pulleys have been used set the alt pulley 3/16" apart. The two being used are P/N F5AZ10334-A also used on F150. The other alt pulley is P/N F50Y10344-FA. According to Terry the two pulleys could have something to do with belt aligment.
Originally Posted by 65DOHCStang

It moves the belt out about 1/4" farther from the alternator (closer to the timing cover). I'll put it on in the morning but I think it will do the trick. The PN for the pulley with Gorsuch's brackets is NOT F5OY-10344-F, which the Trilogy kit uses. The correct PN is F5AZ-10344-A (Motorcraft GP-712). At least that's what works on my setup (and his).
