Servicing my Skyline V37 oil and filter.

[Pac]

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).

yeah its the same.

Haven't heard of the water pump leaking as a common issue.

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
