Replacing Coolant hoses on RB25DET R33 R34

The other week I had a little coolant hose blow on my S2 Stagea RB25DET NEO.

After replacing that hose (the little elbow behind the engine) I decided to replace all the coolant hoses.

I bought a seven piece kit coolant hose kit. It supposed to fit on R33 and R34 Skylines.

Has anyone fitted one of these?

Someone got some photos of the coolant hoses under the intake manifold etc?

Thanks in advance

There's no easy way to do this job, just get to work pulling the manifold off. There are a bunch of photos all over various forums but seeing a photo of them doesn't make this job any easier.

The problem isn't finding the hoses, it's reaching them with tools.

Careful with the ebay kits, I believe the R33 and Neo hoses are different, I'm sure you can make it work but just keep it in mind.

Taking the manifold off that sounds a bit extreme, Hopefully I won't be needing to do that.

I thought there would be tons of information on doing this.

Sounds like you should make a guide on how to do it with the manifold on!

The two radiator hoses fit ok.

This hose looks similar, but factory hard pipe is like 10mm while inside hose is like 16mm.

I'm not sure about this hose, There is something similar, but about half as long. Maybe its a R33 hose?

I'm starting to think this kit is less than ideal.

Thanks for the awesome pic! Another pic focused on the other end would knock my socks off ;)

The top radiator hose looks like it needs to be shortened, to take the kink out of it.

Man you must have super vision, but yeah there is a bit of a kink there.

I'm thinking of returning this kit if hardly anything fits.

One of the guys at work has a R33 GTS-T so I can check if some pipes fit his car. If they don't fit either they must be real crap.

I wish - had the same issue a few years ago so it wasn't hard to see it in the photo. I cut the hose a bit shorter, and it has worked fine for 3 years or so. The hose kit we bought had 12 or more hoses, and I still haven't worked out where some of them go.

This end? Ive only got a few pics of it at different stages of removal so i can work out what goes where  later. The other pics dont really show any more than these but are a bit more zoomed in on each section.

Yeah the lower hose has a kink as well on the top elbow. Do you have details on where you bought the 12 hose kit from?

Thanks again for the pics NEO25T.

They were from an ebay seller, but too long ago to shown in my account.

We bought the kit mostly for the radiator hoses, and fitted them and a couple of others when we got the kit. Have since fitted most of them when the engine was out - no way without either pulling the engine or the intake manifold. Still have a couple of hoses left over - no idea where they were supposed to go.

I returned the seven piece kit to Ebay seller automelray. I think this kit is just for R33.

Then bought a two hose R33/R34 GTS kit from Ebay seller ozcarjz. The kit fits perfect (no kinks ) except the hose is larger at the thermostat. I thought it was leaky because my thermostat was rough. So I bought a new Nissan one from Kudos Motorsport for $55 plus postage. But the hose is way too big at the Thermostat. So i'll prolly need to return that too :(. While the previous kit fitted ok with a couple of kinks.

Not sure if ill ever be back on the road.

I'm looking at doing this atm but have been putting it off for over 8 years because there is too much misinformation and bullshit...did you  have any luck, i mainly want to do the cooling hoses not so much the heater hoses but i'd do them all if i could find a near perfect kit.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
