Hey guys

i just bought a r34 gt-t skyline and owner assured me the timing belt and water pump had been replaced with genuine nissan part (97000 k's)

today i went to work and it leaked all the water and it started making some whinning noises, i put some water in it and it started leaking from the water pump

just to be sure, is the water pump the device which is attached to the radiator fan? it seems to be leaking from inside the unit and dripping down.

can this really be a new part? any ideas?

if so any good mechanics to help me replace it? i live in the liverpool area.

cheers guys.

Yeah that sounds like the waterpump to me.

It looks like this underneath:

Thats mine when i did mine.( The long shiny bit right in the middle :P ) The 4 little studs is where the fan bolts to.

You do need to seal it with a sealant, maybe they missed a little bit, or didnt tighten the bolts up properly.

If it was done at a shop, then its on them. So take it back.

yea thats the one mate

but see its been changed less than 1000 k's and it does not look anywhere as clean as your one does? im possibly thinking it might of not been changed.

was it easy to chnage yours? is it a straight bolt on or did you have to remember the position of the timing belt or what not?

Well youve got to remove the timing belt and everthing else before that and also the idler and tensioner bearing are in the way so they have to come off aswell. Taking off the pump and installing is easy just gota make sure the old sealant is all scraped off and clean before puting a new pump and new sealant.

you can get away with just removing your idler and tensioner but you will have to keep the tension on your timing belt at all times. i did it by cable tying at the top and bottom. when i put it all back together i put the idler first then the tensioner slides in once you adjust the slack (make sure you remove your spark plugs to remove some resistance from the combustion chamber). then check if all of the timing marks line up.

I didnt realize the elongated hole was an N1 thing. Mine clearly has the "N1" elongated hole. It isnt genuine Nissan or anything either.

Random.

Oh and as to your question.. listen to these guys.

I attacked the lot when i did mine. Cambelt and everything. Didnt really know what i was doing but had a crack and seemed to turn out ok :P Only took me 6 hours :pwned:

i heard something about the N1 pumps going on standard motors - because they are designed for motors that spend more time near the higher RPM range they dont flow as well down low (for daily driven cars). some people overcome this by fitting a smaller pulley to speed it up. dont quote me though.

just do it but give them the same warning i give to all my friends and familys cars i fix..... if it breaks, leaks, sets fire or blows up i accept zero liability.... now sign here pls lols.

my N1 water pump started leaking from the housing with just over a year of street use on my built RB26.

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.

      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
