2012 Z Factory Oil Cooler - PIC AND PART NUMBERS INSIDE
 

Ladies and gentleman, below I give you... the 2012 Nissan 370Z OEM water-to-oil cooler. Sorry for the dark picture, but this is from a dealer who was nice enough to put a 2012 Z on the lift and snap the pic.

2012 Nissan Z Oil Cooler part #21300-SS370



also of interest...

2012 Nissan Z Chassis Brake Cooling Kit part #E4420-1EA00

Get any pics of the ducting?

cool. that's wat i was kinda expecting. :)

yah, pict of the ducts would be cool. there was a member here that routed from the fang faux vent and ended up with higher temps than without. :icon14:

Thanks for the pic. This is what I was expecting too.

Thanks for getting the pic :tup:

The dealer didnt get ducting pictures unfortunately, wish he had.

You sure about the ducting part #? It comes back as a Nismo 370z strut brace kit.

Oh, maybe he misunderstood me.. apologies on that

Very interesting.... who is going to be the first to try it out?

How efficient is a water to oil cooler vs using air?

interesting

Now all we need is somebody with a 2012 to go flog theirs and report on oil temp.

^^ indeed. be funny if the water overheated instead. :D

http://www.nissanraceshop.com/produc...70z-21300ss370 0_o something isnt right LOL

It likely will, but it will take a lot to get there. I'm curious if they adjusted limp mode lower. Exposing 300* oil to coolant is idiotic

They've been offering this for two years now. You can get this part as a seperate NISMO part and I don't think this is the same oil cooler that's in the 12 Z's this is an actual racing cooler.

No sir it is not. Also not covered under factory warranty if installed.

yeah...it's not a water to oil cooler!

We have the Nissan Motorsports Oil Cooler -- 5 in stock!

i've never seen a water to oil cooler

Scott

have ever seen a car before? they are very common.


This cooler is obviously passing coolant, as you can see.

There are about 5 threads all talking about the same thing at the same time. :icon14:

Overall, superior. Faster warm up to ideal operating temp, easier to maintain ideal temps. Water does a much better job than air of absorbing heat.

Someone from Nissan actually called me regarding my query on this for those of us with 2009-2011 models... will report back after I return the call.

If water cooled is better then why hasn't any aftermarket companies design one that is water cooled for our cars? That was one of the things that had me thinking.

Because it generally costs more, there is a bit more r&d from what I gather...

Please correct me if I'm wrong on this.

The same reason that some cars were once air cooled -- fewer parts required, and therefore less cost.

But most of us (outside of fans old Porsches) prefer water cooled motors...

It's more of a debate with intercoolers for FI applications because cooler really is always better, and in some situations, air-to-air coolers will work as well or better as water-to-air.

For oil, cooler is not always better. Geting up to operating temp quickly and being able to stay there with little fluctuation is ideal.

Because it probably requires modding the radiator

It's inferior in terms of cooling, superior in consitency.

The two smaller temperature deltas make cooling through the rad less efficient.

Well... right. But cooler isn't always better -- I'm thinking specifically in terms of what would be ideal ("superior") for a DD; for a track only car, air is fine, notwithstanding leak issues.

...

Actually, I just found your commentary on this in another thread, and we are on the same page in terms of what kind of cooler tends to work best for a given application :tup:

Hey -- hang on -- did I just read that the cooler isn't easily backwards compatable!? :icon14:

Is the radiator P/N the same for the new cars? I don't understand why you can't just plumb it in if it makes use if existing lines.

It can't be that different?! :shakes head:

At this point we don't know. Unknown's service manager says it is not backwards compatible---I will reserve judgment until after I see it.

The oil cooler lines are usually a lot smaller, so you would have to tee after your current radiator lines into a smaller one. Can you say, coolant leak?

You wont necessarily have a coolant leak. It's pretty easy to seal coolant hoses. I would not tap into one though, you could find an inline hose adapter, although the sizing of the ports needs to be big enough.

Something like the coolant tee at the bottom of the link below.

I'm not getting how the pictured oil cooler works.
A coolant line is shown running to the sandwich-adapter between the engine and the oil filter. Are there galleys in the plate that the oil is passing through to cool down on its way into or out of the oil filter?

Nevermind. I Googled up an image of the S2000's unit:

So what's the verdict? Is this Nissan oil cooler better than the Setrab coolers that are sold aftermarket under different names or what? Right now I'm looking into a 25 row with thermo-blocking plate. Would this unit be better or worse?

Wish I had known this was in the works before buying my 34 row

These new OEM water-oil cooler will probably keep oil temps down during hot climate/ stop-go driving or maybe even some spirited type driving. No way will it be up to par for any kind of track use. Since I will not be tracking my car, I think I'm going to buy this instead of an air-oil cooler.

Aftermarket air to oil cooler better for keeping oil temps down. OEM water to oil better for stabilizing oil temps. No track use just street OEM, track use aftermarket.

Hmm... interesting... waiting to see how it works out for others... my Setrab is amazing but it does take a while for it to warm up in the colder air (no block off plate). This would make oil changes easier too.

Since I am not a gearhead, any one would like to chime in and discuss if this 2012 factory cooler can be retrofitted to pre-2012 Zs. If so, what is the level of difficulty involved in self-install. If at dealer or shop, ballpark cost for part+labor.

Thanks,
