[shanec86]

hey does anyone know where i can find another fitting for the RB25 NEO water outlet to radiator (on the intake manifold) it has corroded and im struggling to find a new one.

[DMT2LSD]

[shanec86]

nope not luck. i dont know if im searching wrong or what. I might have to get some made up if theres interest

[mystery_kid]

going to state the obvious here

ring nissan

You can take the manifold off and get a pipe welded in place (any ally fabricator)and a bead welded on the end to stop the hoses blowing off, i did this with my 20DET to get rid of the adaptor that steps the hose to a smaller diameter, didnt cost much and it works fine

Nat Rad sold me a cut of pipe that fitted straight in there

Ill also link you to another place

UAS Chrome Molly Upper Radiator Outlet Intake Manifold

Replaces often rusty factory one.

PRICE: $65

This is what mine looked like

[shanec86]

thanks for the help guys

i didnt bother to call nissan because there is no listing in fast anyway, it looks all part of the manifold

[MrStabby]

That part looks like it is supposed to corrode - that is - be the "sacrificial anode" in the electric circuit created by the coolant. In older cars i've worked on the thermostat housing typically performed this function. If you want to understand why, google galvanic corrosion.

tl:dr - only use the replacement Nissan part so that the head and/or block dont start corroding.

Holy crap! It looks like tap water has been used in that cooling system.

Hi all,

Apologies for the thread revival...

I have a similar issue.

Has anyone else found another alternative?

cheers

[Gameboy]

Hey guys, sorry for an old thread bump, but I also need this part for a freddy intake manifold

[scotty nm35]

I could easily spin one up from stainless or ally on the lathe, but I am sure they are available still somewhere...

I would be welding an alloy replacement fitting on there.

[Karakuriser]

Does anyone have any suggestions on how to get the rusted outlet off the engine?
Mine currently looks like the pic Manuel Kasko posted above and I have no idea how to get it off without leaving half of it behind.

[tridentt150v]

Mine is corroded but not so bad I have to replace it just yet, but when I looked I was going to cut it way using a dremel and a tungsten bit. So slot it and then collapse it. Not sure if thats the best method but reckoned it could work. Be careful not to hit the alloy though, don't really want to scuff it too much.

Pretty sure you could then mike it up and get an exhaust place to make up a new one, if you only have to do it every 15-20 years trhen I don't see a big problem.

I had that issue about 2 years ago, I thought I posted here but I'll chime in Now

I took it to a mechanic and he said he'd seen it heaps, he said he would use a chisel and then collapse it like the other person above has said, then he had an exhaust place make a piece and roll a lip in it

I didn't want to have half a go and do something wrong and then have to tow it So let him do it for me
