Radiator and heater hoses

[FunkBrother]

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.

my guess for heater and radiator hoses would be supercheap auto

unless u wanted some braided ones

Thanks for that KamikazeR33, will try Supercheap.

I was still wondering if anyone has changed the heater hose on their R33 before, I don't want to get halfway through and find out I can't finish it.

Where is the heater hose? i woudlnt mind knowing i have done all the radiator hoses but not the heater ones.

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)

oh thats right...i know where it is.

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..

Thanks for your help guys. Will post here with the results for future reference.

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

I got a high pressure nismo radiator cap from UAS in sydney a while back!! should give them a call see if they can get one for you, haven't seen one in stock lately!!

they have replacement silicon radiator hoses too, but not too sure about heater hoses, might find out myself actually!!!

hope this helps
