Noise at startup

[jethead98]

Hi Guys, l have a noise which sounds like a worn belt , but unfortunately still there after changing all belts. Removedthe power steering belt, still there, Removed the water pump belt, still there, removed the alt drive belt, no noise. thought it was a noisy bearing in the alternator, replaced the bearings in the alternator and noise still there. The noise goes away within about 7 -10 seconds of start, don't hear it again.

Its pissing me off

Any ideas:(

If it was a 31 I'd be saying its lifter noise.... but if it only happens on start up, then it's probably a similar problem... things kinda clunk around until they get oil on them.

does it stop once the car has been started? sure its not the fuel pump priming?

Ok let us get closer to the problem, is a squealing,whining, taping or clicking niose:D

And does it happen on every start, or only cold starts or only hot starts.

We're not mind readers, give us some info.

Hey guys, it is only at startup, mainly cold starts, its a squeal, like a belt noise, as i stated, it was still there after i slackened off the two outside belts, the fan and powersteering belt, it stopped when l slackened off the alternator belt. All belts are new, the bearings in the alt have been replaced.

Now to my line of thinking, all that is left is the balancer....

Can that make a squealling noise, can the outer turn on the inner???? They do have rubber on the inside right??

not happy Jan

Thanks DRDrift, will call ya...

Um you say you loosened the belts, but out of general curiosity have tightned them to se if it goes away as it may be slipping

[blind_elk]

Yes, that squeal is generally indicative of a loose or slipping belt. Try tightening the belts back to their proper tension.

I think there's a spray or something also that you can use to stop it.

I have the same problem and it is not a loose belt. If it were a loose belt, it would happen more often, not just on cold startups. It would be very evident when revving the car on a cold night, when the engine is cold too, and this doesn't happen.

[inark]

actually i think i know the noise... mine does it too... sounds a bit like the power steering noise in older type cars...

[Zahos]

mine sounds like someone's squeezing a ducks balls!!! If that makes any sense...

[inark]

lol now that i have to hear

i will go make a video of the noise and post it and see if its the same noise jethead

[inark]

would help if i had my camera lol.... will have to wait another half hour for the gf to get here

Calling in to see DrDrift on sat , will see what he thinks of it, keep ya posted:burnout:

I also had a few whirring noise on cold startup, even worse steering make horrible sound when turning... I thought my front steering assembly is about to go or even pwr steering pump abt to die, or some belt is getting loose...

Then I noticed.... power steering fluid a bit low. So I top it up then..... I never heard that sound since again, cold or hot don't matter anymore...

When i had the beast dyno tuned, the chap from Race Pace drove his Gtr out of the shop for mine to go in, and guess what, his made the same sound.......

well, I had to ask....

Bloody Fan belt he Said...

Tighten it till it stops the noise......and then a bit more to allow for stretch, specially on a new belt......

All quiet again.........Nice
