i recently discovered a very very fast leak of coolant through a turbo coolant feed that had previously been blocked but leaking alot again.

iv topped the radiator back up from near empty, only to discover while driving that it is squealing (similar to a slipping belt)...

now...

i have noticed while driving that when im not accelerating or have the clutch presssed in, the squealing goes away. it is also louder between 80-100km.

i imagine if it was the waterpump it would constantly be squealing whether the clutch is in or my foot off the accelerator.

im thinking it could possibly be a slipping belt but its only happend since the radiator was very very low (possibly causing the waterpump to starve from any liquid) SO... i sprayed a bit of stop squeal belt conditioner on all the belts, but still does nothing to stop the squealing...

it seems its pretty obvious that the waterbump is the cause but just need to be certain that its the waterpump before i replace it.

cheers

Not much to go on here!!

The 'waterbump' [haha] turns with the motor, so it should squeal all the time. It could also be the air conditioner compressor, the alternator, or the power steering pump - if it is that type of sound.

You can usually check the water pump by getting the belt off then spinning or wriggling the pulley and looking for play etc, it will be really tight [ceased and unlikely in your case] to turn or wobbly. Usually get a fluid leak out the seals if its flogged out, thus your fluid loss.

When you topped up the fluids [and if it was that much] did you undo the air screw and bleed the air out of the system?

hey, few days my car was making a strange squeking noise too. not laud just so u can hear it at idle, didnt think much off it must of been a belt or suem...

then my car started to leak water not alot thoe ,

but yea i thought was air con or the wiper blade resivour thing coz i was out for a bust :S again i didnt think much off it..

i got my car back yesterday coz it was impounded :( and on the free way it alomost over heated i let the car cool down and i toped it up and i got home sweet.. but im loosing water constanlty :(

i had a look from under the car and its commin from the pump,. right behind the pulley theres a little hole and its just pouring out of there every time i top up, is it as simple as the wash plug fell out or som thing serios??

thanks

    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
    • Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...
    • No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.
    • You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever
    • Thanks for the quick reply. To be clear, when you say turbo shuffle do you mean turbo flutter "stustustu" or referring to something else? I had thought they were the same thing. When I wrote the post my intention was to say it wasn't a flutter/compression surge sound. My understanding was that a flutter sound would be occurring when throttle is released, whereas I can keep the throttle in the same position for this noise
