(Rb25det intake manifold)
I’m having a hell of a time trying to find the full part or part number of this coolant hardline

so far I was given these (Below) but they aren’t what I’m looking for and was told it’s the IAR or aac valve but that doesn’t seem to be it either. If someone could point me in the right direction it’d be greatly appreciated. Or if anyone has it for sale that’d be great too. I have recently purchased a greddy manifold and I can’t seem to find my old one to pull it off. 

  • (Front Heater Return / Water Pipe (under intake):
    • Primary part: 14053‑21U10 (front return pipe assembly for R33/R34 RB25DET)
    • Alternative listing: 14053‑21U00 (same pipe, sometimes interchangeably referenced)
  •  
  • Heater Feed Pipe:
    • Listed as 14075‑04U00 or feed-related variant 14053‑AG500)

So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it.

From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose

If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.

Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun ....

...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.

    • Sane enough. Remove the roof liner, because the acid will go everywhere.
    • Thanks guys, I really appreciate the help and experienced opinions.  I have spent a lot of my life working on boats so I'm pretty good with fibreglass. I'll take everybody's advice in here;  I'll cut a little more of the 2nd layer away as it's a bit crunchy rust and also it's sitting high now. Then I'll wire brush it all a bit to get off anything loose, then I'll soak the bejesus out of it all in rust converter. I'll make sure to get a little hose piece and feed it into all the holes and gaps between the roof layers. Then I'll fibreglass up the holes.  Then I'll get a pallet of filler and mix it with 3 buckets of hardener and hope that is enough to build up the roof corner.  Does that sound sane? Is one type of filler better than others for this?
    • My goals for it atm are to get it registered, respray and some mild power gains eventually... I picked up the car from an elderly gentleman near the border of NSW and VIC, its honestly a bit rough and looks like its been driven on a farm (because there was so much dirt underneath). Last week I dropped the subframe and emptied the old fuel out + added a new fuel pump (think the old one went bad from old fuel). Now I'm onto fixing a coolant leak at the rear of the engine + adding a new radiator as the old one is corroded. After that i have a new bumper, coils (as the old were leaking) and lots more
    • Welcome buddy! Plenty on here and YouTube. What are your plans for it? Good luck with the Rwc and Rego bud!
    • Love this so much! Please post a photo when you have a bike on the trailer.  I was a little bit worried about having a tow bar on the Skyline, but having it hidden behind the number plate is genius
