squeeling noise on startup

[HPerboost]

Hey all

Just recently my 33 has developed this squeeling noise on startup it sounds like a engine drive belt but they are all tight and in good condition so that isnt the problem. It will make this noise three out of five times it is started so it isnt constant. I was told it could be the clutch on the engine cooling fan or somthing in the strater motor any help would be sweet as its getting worrying thx dudes.

your going to need to describe the noise and when it occurs a bit more. Is it only when starting the car or just after started. How long does it last? ( ie as long as your turning the key)

[HPerboost]

It happens when the engine starts not when it is turning over and lasts 1 - 2 seconds it kind of sounds like a loose or slipping belt such as a alternator belt that is as close as i can describe the sound.

[Sledge]

If your certain on your belts then I'd be looking at the starter motor next. You could have a faulty/slow returning solenoid. What this means is that the starter motor is being turned over by the engine for a second or two until momentum returns the idler gear. The solenoid is the smaller of the two cylinders on the starter motor and is responsible for the throwing in and out of the gear. It could be as simple as the return spring being broken or dissengauged.

Thanks sledge i will get it looked at its not a belt so it must be the starter not disingaging fully hopefully its not 2 many dollars if it is..

R33, if its this, i wouldn't expect more than $100 to remove and install then another $100 for parts. But don't quote me, cause for all I know it could be something as stupid as a sqealing timing belt tensioner and they charge you $600 cause it took them all day to get it out and back!

sledge is spot on , thats the likekly cause the starter drive but if u go to an auto electrician they will just sell u a reco starter on an exchange .

Ive got the same thing....sounds like my alt. is clicking every second at 1000rpm when cold...if the car is warm, it doesn't do it...belts have been changed and water pump replaced....im thinking its something with the pump as i left water out of the radiator while the car was running and it stopped for 5 sec...?

I had a similar noise when starting and all they did was grease the starter motor shaft and it hasnt done it since so if youre lucky it may be as simple to fix as that

It's your belt tensioner. Mine did it too after a belt chain as does half the bloody skylines I've seen around the belt change time.

please explain

[wrxhoon]

if u think it maybe the alt , take the belt off if it stops well thats it then if it doesn't then u know its not the alt .

but u should be able to tell the alt bearing noise is diff to the starter gear noise ..

i replaced all my 3 belts yesterday due to annoying squeaks.

the old belts dont look that bad for condition. but with the new ones on its quieter than its ever been.

as said, take em off one by one... you'll find the culprit

i get this loud squeeling noise on cold start ups once in a full moon......lasts for about 3-5 secs. scares the crap out of me. i wonder if its the same prob as ur describing Hyperboost.

[2rismo]

Mine did this too.. grease up your shaft boyo!

my mates silvia does this all the time but only when the aircon is on.

[Brody]

If i take off the belts, do i need any fancy tool or need to take alot apart? I don't want to risk snapping a belt or something and being fkd

[wrxhoon]

no just normal spaner or socket . the alt belt u loosen the alt so u can move it in to remove the air cond same whaen u tighten them make sure they are not to tight as long as they dont squeel that is tight enough.

[Brody]

I had a massive amount of noise coming from it last nite, i think my water pump is going to go...again. Ill take it dow to my mechanic, think my problem is abit more serious

[HEL-RZA]

B4 u go 2 a mechanic try spraying some belt dressing on there. My 32 used 2 squeel like a pig, but after the belt dressing it never made a peep. But u will need 2 reapply it every couple of weeks or so. Hope this helps...
