Radiator and heater hoses

I was doing some maintenance on the weekend and when I had a close look at the radiator and heater hoses I noticed that they are probably the same ones that have been on since the factory. I gave them a squeeze and I could hear them cracking on the inside and they were really soft.

I figure it's worth changing the lot now as it's not worth the risk of one failing, would probably need a new engine. Preventative maintenance is a lot cheaper.

Has anyone else had any experience in this? I asked if they had radiator hoses for an R33 at Autopro but they said no. Will I have to order them from Nissan? Does anyone know where I can get them from?

I can change the radiator hoses myself but I'm not sure about the heater hose. I tried tracing it back and it looks like I may need to take the manifold off to get at it. Has anyone attempted this before? or would you advise getting a mechanic to do it.

I also would like to know where I can get a radiator cap, I haven't tried any auto shops but the one on there looks smaller than standard, I think it's rated 0.9 kg/cm2.

Thanks in advance.

Matt

Heater hose runs along the back of the engine bay, up against the firewall. If you look behind where your turbo is you should see to pipes going into the firewall, one of them should have some heat shielding (I think) on it. If you follow it back it ends up on the manifold side down to the rear left hand corner of the engine (I think).

I'd investigate R31 radiator heater and radiator hoses, should be fairly close close I'd say. Just take one off, go into the shop and see whether they can find a match.

The only time u might find it hard is if you have some special one that needs to wrap around your FMIC piping (if you have one)

Ask your local nissan dealer for a radiator cap, they will probably be able to get you an equivalent. I lost(dont ask how..) the cap to my radiator overflow bottle, and it happens to be the same one as used on nearly every nissan since 1994 according to the dealer. So yeah it was $12...ask about the radiator cap..

u should be able to change ur heater hoses without removing the manifold , i haven't looked in the gtst but i have done it in the r33gtr its hard to get to but doable .

if the hose doesn't have sharp bend in it u may be able to use normal straight hose but if its short and with 90 degree bend u may have to get it from nissan or u may be able to get it from auto 1 , supercheap or other aftermarket resellerl

      @joshuaho96 Hmm considering the drama you've seen/experienced, have you looked into getting a built complete long motor shipped from Australia?  Considering the AUD is basically monopoly money when compared to the USD, at a glance this seems like a good option?

      Bloody Skylines, they put you through the bloody wringer! Stick at it! Stunning drag strip BTW! Where is it? Can see part of the name on the slip and probably should just Google it!

      I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).

      At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself

      I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad.
