Cooling System Hoses

Hi Everyone,

Well while I was 600km from home I had a heater hose leak (R33 gtst). I made a bypass and have made it home, all good, no overheating issues.

Now, I guess it is time to replace as many hoses as possible in the cooling system. So how many hoses are there and where do I get all these parts from?

Can anyone tell me the part numbers for the heater hoses and any other necessary Nissan parts?

I will replace as much straight/small hoses with Pirtek generic hose I guess. And the radiator must need replacing too, so I guess I'll get one of those Mspec ones?

Anybody done this to an R33 GTST and can help me out with some advice? Is there a kit and a Nissan part number?

So far I have found:

Heater hoses (4) in silicon by samco (UK) for R33/R34 and R32 GTR. Worth a look if you want quality.

Ebay also has a 14 piece kit for the GTR (includes oil, air and water lines). But quality could be a bit unknown for pressure.

I am in contact with Nissan atm, will give part numbers when I get them.

This is on my to do list as well, dammit, that list is so long.

Gates Racing make very good quality hoses, I have used them on other cars and they are much better than the stock ones, they tend not to go all soft and loose around fittings after time like other hoses do. I'm not sure about them making the heater hoses though, I know they make the main ones.

But Samco only make for GTR, pity.

I've got a pic of the heater and cooling systems from Nissan, I will upload tonight or tomorrow.

Got 2 heater hoses and the white plastic 4-way joiner thing on the firewall on order.

I will also get Gates radiator pipes and the Mspec radiator. I will replace the other hoses next year - hopefully by then someone will make a silcon kit or something. Surely there are hundreds of R33 GTST owners out there who must be so close to needing new hoses, mine is a late 96 and it's time. What about those older car owners?

I did this very thing on my gtst. I had one of the rad hoses let go and figured they were all the same age and didn't want a coolant hose to keep leaking every second week.

I simply went to nissan (brighton here in Melb) and said I want every coolant hose replaced....they did all the hard work sourcing the hoses (no kit, although some hoses come in pairs etc). This was about 3 years ago so I don't have the receipt but from memory it cost around the 800 mark for all the hoses and clamps + labour to get them done. Not cheap but gave me piece of mind and I never had another problem.

Oh yeah and I'd def go genuine hoses as they are rated to pressures and temps. Other non genuine hoses NEVER seem to last as long as the genuine items.

Here are the diagrams as promised for R33 Series 2 - RB25DET

Part numbers can be hard to make out, but these were supplied to my by Nissan parts person. There are prefix number to be attached to these, but now you can see what they see when looking for your parts.

The thing in the top corner of the heater hoses is the white plastic part that goes on the firewall - I got a new one of these today.

      Mistakes were made, my R34 Story

      By MBS206 · Posted

      I agree with everything else, except (and I'm rethinking this as it wasn't setup how my brain first though) if the sensor is at the end of a hose which is how it has been recommended to isolate it from vibrations, then if that line had a small hole in, I could foresee potentially (not a fluid dynamic specialist) the ability for it to see a lower pressure at the sensor. But thinking through, said sensor was in the actual block, HOWEVER it was also the sensor itself that broke, so oil pressure may not have been fully reaching the sensor still. So I'm still in my same theory.   However, I 100% would be saying COOL THE OIL DOWN if it's at 125c. That would be an epic concern of mine.   Im now thinking as you did Brad that the knock detection is likely due to the bearings giving a bit more noise as pressure dropped away. Kinkstah, drop your oil, and get a sample of it (as you're draining it) and send it off for analysis.

      I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.

      Help! Leak coming under transmission

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
