NISMO,

If I was to guess at it I would say that the alternator bearings are on the way out!!(these can sometimes make the exact same sound that you describe so I would check this first) But to check it you would have to remove/loosen the belt to see how easily the alternator spins to make sure!

There was a thread on this a while ago, but no resolution.

I have the same problem.... When its cold, you start the car, and you get a screech (intensity of sound depends on how cold it is), and it will last about 1 - 2 seconds.

I've had this prob for over 6 months now, and I have no idea what it is. As it only does it when i start the car, and the outside ambient temeperature is low, AND it only lasts about 1 second, I haven't bothered to fix it!

And no it's not the fan belts,

Doubt it is the alternator bearings, as it would do it more consistently...

Can anyone else that has this problem, please tell us if you also have a squeeky clutch! As in does your clutch squeek sometimes when you depress the pedal?

Zahos,

I have a auto(Not for long though) GTS4 and I have experienced the same sound on start up (only twice so these would have been cold outside and that the car hadn't been started for one week) so I don't think that the start up noise is related to the manual gearbox.

It seemed to come from the front of the car where the alternator is located?

It also happened after I fitted a new fuel filter and had to clean the engine bay again I thought that a unsealed bearing had got a bit damp because I only cleaned the drivers side of the engine bay.

I can't actually diagnose the problem because it has only happened to me a few times and is inconsistent enough for me to leave it alone until I put in rb26.

where is NISMO?(the one who started this thread)

Thanks for that Mega!

So now I'm left with no clues as to what it could be! I would think that if it were bearings that it would do it more consistently? A friend had the bearings go on his air-con, and that made bad noise consistently, wouldn't the bearings off any component working off the fan belts do the same thing if they were buggered?

Anyhow, summer is coming so I guess I wont have to worry about this one for a while!

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
