Aye boyz ,I m guessing I need a new fan ,car is a 32 gtst .

Cruising around then I could hear the engine it was louder then normal,Its nothing to do with driveline as it makes the noise whilst parked .

It sounds like the fan and it s blowing pretty hard ,as you rev car sounds like a nissan patrol ,Pretty sure not the motor itself (hope not)

Any one heard of this happening, fan goes into hypo mode ?any more then 3000rpm sounds like gonna fly threw the bonnett.

feedback appreciated will post up how I fixed this problem

thanx guys

The fluid clutch in the fan is seized, meaning it will spin at whatever you rev the car to, usually they're setup to not go above a certain rpm.

Get on to this ASAP because they have been known to let go and go thru bonnets. No Joke.

I just recently developed the exact same problem with my R32. Pitchd mentioned about getting a newclutch fan from FBI. Where is this place? Is it located in Victoria or are there any places that supply these in Victoria. What's the estimated price for a clutchfan.

i too have this problem. i got a new fan in today and when it started to get hot i began to have this problem again, and its been going on through the night. so i dont think its the fan coz it was just replaced. could it be because the cooling system isnt sufficient enough for our Australia weather? if it is what could be done to reduce it? any answers or ideas to the issue would be appreciated ASAP.

thanks heaps... Stephen

the clutch fan cuts out at 3000 Rpm.

I bought a new clutch assembly for mine. It was a craig davies replacement. On the box it had a whole heap of other model skylines it could be used for as well as the VL turbo RB30et. (rb30e has a different length and thickness shaft on the clutch)

From memory i bluffed the guy and got trade price @ $120

yeah ive found its onli on hot days. i dun think it could be the fan coz its a brand new one. is there any way to eliminate it if the fan isnt buggered? coz i seem to be losing power while it is happening aswell

The fan is operated by a small coil that uses temperature to engage itself.

On a hot day the fan would be on most of the time (below 3000rpm)

As a side note, the fan runs off the waterpump. Have you guys replaced the waterpump at anypoint? A shagged bearing in the waterpump will make the fan harder to spin, and can kill your car if it seizes...

Mine is fixed ,just got fan from wrecker ,

I can still hear it a lil bit but no where near as loud as before ,

I got better probs now i clened the cold start valve thing because car never starts whilst cold unless give it some throttle. and now my car idles at 1800rpm wha ,guessing car was fiddled with to compensate for a dirty cold start valve ,hope I can fix it my self gonna give it a go in the morning .Throttle stopper screw and tps I'm hoping will solve high idle

PS I hate skylines (my excel went for years no probs)lol

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
