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

different setup mate, this is an external electric pump and timing chain on VR30DDTT

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

    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
