New Water Pump Leaking..

[kaw10r]

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 ) 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.

Was it an N1 pump that was fitted?

They fit most RB motors, but there is one screw hole that is elongated compared to a standard pump which if not sealed properly will leak.

Here you go, N1 pump at the back. As they're pretty cheap people do use them on non N1 engines.

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 Only took me 6 hours

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.
