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

Brendan

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.

      I think the pic in the first post is another car, and post 7 is OP's car with standard arms and swaybar swaybar swaybar. I can't tell what brand the silver coilovers are, and even if I could I don't know whether the spring rate is OK, if you can find a brand on the shocks and numbers on the springs that might help. Also, if you can measure the ride height from centre of your wheel to the guard that will help with advice too as handling suffers if ride height is too low

      In the first photo you posted, the colour of the control arms are the signature colour for Ikeya. Same for the swaybar, signature colour for Whiteline.  I like Hardrace, they also do hardened rubber bushes if your car is mainly a street car.  I like GKTech as well, but they use a lot of rose joints in their stuff so might not be the best choice for everyone.  The system might have been good back in its day, but it's a prehistoric system now. I suspect that most people have removed the HICAS as they want the car to do what they want to do, not what the car wants to do. From what I also understand, it isn't consistent in it's behaviour on track so it's hard to trust the car/know where its absolute limits are for track use.  Having said that, I think the HICAS eliminator kit was the first thing I installed when I bought my car. I don't personally have any experience with the HICAS system on a race track.

      Thanks for the info. Didn’t know I had aftermarket control arms already? Will talk to my garage. What brand would u recommend if I want to play around with my camber more? I would think my camber is around stock level right now or more negative now due to lowering with coilovers. I will be lower her again 1.5 cm to get some more.    also why does everyone like to remove the hicas system? Is it because most don’t work properly anymore or ppl just don’t like them. Mine is functioning as it should be right now.    thanks for the good info

      It looks like you've got Ikeya control arms and an aftermarket sway bar, maybe whiteline?  Or am I just going crazy? lol Unfortunately it won't, but what it will do is look really pretty. That's about all unfortunately.  How much neg camber do you currently have? Generally lowing the car dials in quite a bit of neg camber as it is. If you do go down this path, your best bet is get adjustable arms, toe arms (or preferably a good HICAS elimination kit) and traction rods. With all 3 being adjustable, you'll be able to dial out any bump steer that is introduced by playing with the camber settings.
