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?

bugger everyone has the same thing here

we need to have a skyline meet lol "maintanence meet"

we can all do our bearings and squeaks at the same time :)

might aget a quote on getting the throwout bearing...or even get someone to look at it and tell me what they recon it is

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!

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
