40 second squeal?

[DxmaSonxM]

So whenever I let my car sit overnight and start it in the morning it squeals for 40-45 seconds then stops. Also it idles around 1100-1200 rpm only in morning, usually it idles around 800. But after that its fine for the rest of the day. I know its probably a belt but does anyone know which one it possibly is?

Usually alternator belt.

Thats what I was thinking. So should I just tighten the belt or get a new alternator?

Well mine does the exact same thing and its hell. What I dont get is what is causing this? Because I just changed my alternator and put a new belt on it, it stopped for a week or so then it started right back.

Tighten up your belts if they squeal. Should solve your problem.

New belts will stretch a little.

Like the others have already said it is probably just your alternator belt as those like to squeel. Sometimes you can just tighten them up and get them to stop and sometimes you cannot. If it has not been changed in a while or you don't know when/if it was replaced, you should just get a new one. A very important thing to do BEFORE you put on a new belt is to clean all the pulleys that the belt will be running on. You can get a buildup of grease/oil on the pulleys which can cause a new belt to squeel right away. If the car sits outside with these cool damp mornings we have this time of year it will make a worn/loose/greasy belt squeel for sure. Good luck

Yeah mine does this too. Only in mornings after the car has sat all night. The funny thing is that I didn't think it was the belt so with the red straw on my PB blaster (penetrating oil) I hit it right at the center of the alternator and the squeel immediatly goes away and doesn't come back tell the next morning? The squeel doesn't sound exactly like a belt as its pretty quite. I am thinking alternator, or bearing on the pulley maybe? All three might get changed anyway...

Our 97 Spyder always squeals the first time you start it.

We tighten belt and it goes away for awhile.

We hit it with WD40 and it quits for awhile.

I have read that changing the pulley on the alternator can cure this.

Also some people have changed to Goodyear Gatorback belts to fix it.

And some people hate the Gatorbacks.

Who knows

Oem belts ftw! I used dayco.

OEM belt are the best bet... Cheaper than new alternator...

Hey guys. Yes, it can be loose belt bad pulley ect.

But on these car this is usually the fist sign of a cooked alternator. when the rectifier in the alternator starts to go for what ever reason it tells the alternator wants to kick out maximum juice when you first start the car in the morning. this creates so much load that the belt squeals.

I cook a lot of alternators on my car due to the glowing down pipe, they all start doing this right before the flickering head lights and eventual failure on some long roadtrip far from home. If you are unsure that this is the problem unplug the wires on the back of your alternator, both the charging wires and the harness wires, and start your car for the first time in the morning. if it doesnt squeal like a pig your alternator needs to be replaced soon.


`cheers

ps. dont forget to tape up those wires so they dont ground out and tuck them some where safe where they wont melt or get caught in the belt when you test this.

Same thing happens to my car, but only for 1-2 seconds when the engine is cold (when the engine is hot is starts perfectly, faster than newer cars even and with no squeals). Same thing?

 

[endeffect0]

yours sounds more like a loose belt, try adding a little tension to them

 

[98dsmkid]

yup had the same problem...like everyone else said...jz tighten you belt and it should be fine, or get another belt...

 

[gusu]

The tensioning system for DSM alternators is just stupid. I have a problem with my bolt being stripped by a retarded friend of mine and now I can't find a new bolt. I tried different places and can't seem to find it. If someone could tell me the exact specs of the 1g tensioner bolt (the long one) so I can order it online I'd be very happy!

Anyway the tensioner itself comes loose VERY easily. The best thing I found was to take it all apart, degrease ALL of it. Soak it something somewhat sticky then tighten it back up with no more grease on it.

Don't forget that differences in temperature will cause it to expand or contract. During the winter you will notice it coming loose A LOT more than during any other time of the year.

Well guys my head gasket blew. Oil in coolant and trans. and this just happened like 3 hours ago. Oh and it was squealing like crazy now, when i drove it onto the flat bed to take my baby away.

 

[BoostedTalonTS]

If you just lost your head gasket, AND you were having belt issues, I would take a good look at your harmonic balancer. These things will squeal when they start to separate... If you were also running higher coolant temps / overheating before you lost the HG, then this might make sense... When the balancers let loose the crank will continue to spin but because the outer part of it is no longer attached due to the rubber bond failing it can’t drive all of the accessory belts sufficiently.

 

[mandrigues]

My does the same thing, but it is tight! my head gasket was leaking oil, and the pullys had oil on them causing the belt to squel. also there is condinsation in the mornings, if you tighten your belts and it doesnt fix it clean the pullys of, if they are wet they will squel!

 

[smcasey1]

sounds like a loose belt to me...

the squeal comes from the belt slipping
