Hello SAU team 

I just had a my 2020 RV37 Skyline 400r serviced by my local mechanic and he has noted that there is a coolant leak coming from the water pump. 

He mostly does European cars so he wasn't sure is this is a common issue with the VR30  and how to address it . 

Any chance anyone can advise on this issue and if I need to replace the water pump (guessing its the same as the ones in the Infiniti Q50 red sport ADM).

If coolant is coming out of the pump bleed hole it means coolant has bypassed the pump shaft seals, so it’s fkd. Do u replace the water pump with the timing belt? (All OEM)

I expect there will be 2 water pumps so you will need to know which one.  Also I think they are much less likely to leak than a mechanical one so I hope they are confident it is from the unit not the hoses/clamps etc

On a related question, does anyone have an online parts lookup that covers these, and a 400R VIN to use? 

I haven't been able to find an ADM VIN parts lookup for the Q50RS

Thanks for the response Guys , so far the mechanic has topped up the coolant and I haven't noticed and further leaks , I'm going to see if there local workshop who might have a bit more expertise on the imports. if the pump needs replacing I'll give you guys a heads up.

I would sign up to www.infinitiq50.org ask there, plenty of owners on there that may be able to advise of any common issues.

The 400R is just a red sport with a few extra cosmetic changes, so mechanically they will be the same.

Which coolant are you seeing leaks with? the engine coolant (which uses a belt driven pump, part number 21010-4HK0A), or the intercooler/heat exchanger coolant, which uses 2 electric pumps.

For a parts listing, try this - 
Nissan Infiniti Q50 with V37-RHD frame, 06.2016 - ... - Genuine parts - Amayama

Quick update Guys , managed to get the water pump replaced . I first my mechanic went back and forth with Nissan AU (4 weeks) and they weren't much help, at the end they noted something about not supporting imports. So I soured the part myself from Japan.

If anyone has similar issue here is the part numbers 

  • Genuine Nissan PUMP ASSY-WATER - 21010-4HK0E
  • Genuine Nissan Gasket - 21014-4HK0A 

Cost me about $230 including shipping (I had in within 10 days thanks to Blackhawk in Japan) 

They are basically the same as the Red Sport or even the new Zed - here is link to a supplier in US who helped me confirm the parts matched

You can change it yourself if you like , but I had my local workshop do it , it was about 5 hours of labour. 

Cheers

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
