Scan your repair order and post it up. I want to see the part number for the new engine.

:icon17: So, you're saying Nissan installed a different engine other than the 3.7L in your 370Z? Perhaps it's the Twin Turbo GTR engine? or does the engine look like this? :bowrofl:

I am new here so sorry if this has been answered, but I will have the nismo 09 model, do these already come with the oil and diff cooler installed??Thank You
Guys

Neither..

370z Nismo here... Haven't read all posts (not even close) Oil temps on highway's stay's about 190 ish. Drove around a lake tonight (tons of twists but maybe top speeds of 30mph) Car reached 220. I've seen it a few times climb a little above these temps. What concerns me the most... Car is under an extreme break-in by the book. 612 miles on her so far. Not revving above 4k like the books says. So what happens to 220 degrees past 4k rpms? I'm scared to find out.

Well that day was today. Although some could argue that 250-260F isn't "that bad..." on a car that is NA and brand new... I would totally disagree.

Today was my first spirited driving with a few WOT pulls and mostly 5-6k strong pulls. WOW how fast that oil rose to 250, it was unreal. It took less than 5 minutes at street temps of 85F.

So before I go to my Next auto X. I was doing some research and came across this site. Has anybody used this product yet? Has it successfully cured the 370's issue?

I know this thread isn't the fix one but rather the "jump aboard the recall" bandwagon. (which I am all for BTW cause... WTF! right?) But I am also not interested in driving my 40k sports car like my grandma. Till Nissan gets their acts together which could take 4-ever. So forgive the link.

It looks large enough to do the trick.


Nissan Motorsports Oil Cooler Kit

FYI if you put on the oil cooler it will bump you wayyy up the class ladder for autox. So if you planned on being competitive without spending double value of you car in modifications/tuning I would not recommend installing that.

Secondly I can say with out a shadow of a doubt that you will not have any issues with oil temps at an autox. I run in Houston with ambient temps in the mid to upper 90's and 60 second courses and haven't had any issues at all. Temps rise to around 230 over the course of a run and are then back around 200 before the next one.

whats wrong with you people hahaha my engine did blow out i have pics of my car up already already and nissan replaced the engine under warranty i had around 6600 miles on it.....

Okay, my dad is about to purcahse a Chicane Yellow 370z. Anyway, did the newer Z's between april and may still have the oil temp porblem? Also, will driving it hard occasionally still have the oil temp issue after break in? Thanknk to all! Also, whould we purcahse an oil cooler when we get the car? Any suggestions?

Then post the pics. :shakes head:

All 370Z's of every model currently made has the oil temp problem till Nissan comes out with a Oil cooler from the factory.

I bought mine in April (6MT, Touring, Sport); oil temps have run 220 to 260, depending on ambient air temp and type of driving (all on the street). I love the car and really enjoy driving it. But, I think this is an issue Nissan should address. I've had several conversastions with Nissan NA; bottom line is they say oil temps at this level are ok and will not result in engine damage. I'm not a mechanic or engineer, so I can not really dispute their position. I can say these are the highest oil temps I have ever seen on a sports or performance car that I've driven on the street. I intend to put an oil cooler on my car; just a matter of finding the right product and the right mechanic to do the work.

Have they still not fixed the problem? Also, should my dad purchase the new oil cooler along with it or complain about it before he buys it? My other question is, If you were going to drive the car hard one day but not for an extended period of time, would the temp still shoot up regardless?

There is no "problem" to fix. A cooler is only necessary if your dad intends to track the car. After break-in there are few reported problems of High temps. This has all been blown WAY out of proportion.

My 370's (under 300 miles) oil temp is running around 120-130°F above ambient while driving very easy, like grandma on Sunday. Once I get past the 1200 mile break-in I'll post what my new numbers are.

I don't run my Z on the track nor do I intend to but do drive it like a sports car should be driven.Fast and furious!
Temperature 92 degrees and very humid here in N J and drove the car for a half an hour at 80 mph and oil temp never went above 225! I assume if I were reving at high rpm's going through the gears upshifting and downshifting and manuevering turns quite a bit it would rise considerably.
So it is my belief that for moderate street use in the summer it will be fine.All this talk about a cooler should only be needed on a car that will be taken to the track.Just my 2 cents for what its worth.
By the way I dumped the ester oil and filter at 2800 miles and used Mobil 5-30 from here on in.Engine quiet as before and don't hear a thing!Topped it off and will watch oil consumption from here on in.

Wrong

Right

No point really. Is your car broken in? (More then 5K miles?). Nissan has already made a statement on this. It is not a problem for street cars. They do recommend a cooler if you track. There is nothing they intend to do.

In case you haven't seen Nissan's statement on this:

To avoid activation of this engine protection system and these reduced peak engine speeds, Nissan recommends an oil cooler be fitted to the 370Z before driving it on a race track. A Nissan Motorsports accessory oil cooler kit is available for customer purchase through authorized Nissan dealerships for race track use. The part number is 21300-SS370.

An oil cooler is not necessary for normal operation of the vehicle on public roads. The addition of an oil cooler would have raised the price of the car and potentially moved it out of the reach of some customers. Value has been a core principle of the Z car since the original 240Z and we choose to uphold this core principle by not adding additional costs that are unnecessary for normal use. For those individuals who choose to drive their vehicle on a race track, the oil cooler is available as an aftersales item.

The oil cooler is a Nissan Motorsports item and as such is sold without warranty, express or implied, unless expressly prohibited by law in which case the warranty provided is the minimum required by law. The installation of the Nissan Motorsports oil cooler does not, by itself, “void” the vehicle warranty.

Please define "high"
 

My car just turned 5000 miles; so it is broken in. I see temps in the 220 to 260 range virtually every day. Once the air temp goes over 85 or 90, oil temps increase to these levels, whenever I maintain highway speeds and normal rpm ranges. I guess the real question is: what is considered "high" for oil temp under normal operating conditions, for street driving? For this type of car, I would hope that shifting at 5K RPM would not cause a problem. After all, it is a sports/high performance car. Cruising at 70 to 80 mph and turning 3500 rpm shouldn't result in 250 degree oil temps; at least not for any other car I've driven in the past. Any insight you can provide would be greatly appreciated.:confused:

Apparently Nissan considers 280 degrees high as that's where Limp mode is engaged as a protective feature.. Not many (if any) guys reporting that on the street..

Okay, thanks for the heads up modshack. Once its broken in, could you still drive it hard for a little bit and then ease off a bit?

Sure! You can drive the wheels off it if you want. 280 degrees engages a reduced Max RPM limit is all..

No, just hit 1k miles on the car today. I'm just really concerned about these temps. I thought for sure this whole thing was hype myself until I saw the numbers myself.

I'm tripping out about these numbers especially since I'm not doing anything crazy in the car. (as my video will show) I mentioned earlier that I intend to AutoX this car and someone said that adding an oil cooler to her will put me into a whole different class. So this issue has got me worried and frustrated. I want to compete in a stock bracket. And it seems like this car's heat issue isn't going to allow me to do that.

ME and many other 370Z owners noticed that this car takes a while to break in. During the first couple thousand miles I have seen the oil temp gauge climb up literally in front of my eyes. But after switching to a good synthetic oil and 7800 miles later, it's a huge task for me to bring the temps up. I'm averaging 95 degrees outside and I'll be surprised if my car crosses 225 F even after prolonged drive. I say wait till your car has 4-5K miles (completely broken in) and switch to a good synthetic like Redline, RP, Amsoil etc. You'll have MUCH harder time bringing the temp up.

Are you attending "brief" autoxing (usually lasts 60-90 seconds with time to cool off in between laps?)? If so you DO NOT need any oil cooler.

Im at about 2500 right now, switched to RP 5w30 and I have a hard time going over 220, and I DO NOT drive like a grandma by any means.

It seems you didn't read the rest of my post. You will not have any issues with overheating during an autox. The runs are short bursts 60 seconds usually and then you have plenty of time before the next run to cool the car.

Nah man, I got it. Just don't want the limitations. *theme song* "We're not gunna take it!"

:iagree::icon18::iagree: Can't say it better than that!!

Not sure if this has already been stated but i got this from Nissan Sport Magazine

i tryed to type this word for word, its on page 44 of the magazine.

So, Who is David Muramoto?

Nissan's statement does not say this:

"branded a NISMO part, meaning that if it is purchased and installed by your dealer, it will be part of the car's bumper-to-bumper warranty."

They said:

"The oil cooler is a Nissan Motorsports item and as such is sold without warranty, express or implied, unless expressly prohibited by law in which case the warranty provided is the minimum required by law. The installation of the Nissan Motorsports oil cooler does not, by itself, “void” the vehicle warranty. However any damage caused by the installation or use of this part is expressly excluded under the terms of the Nissan New Vehicle Limited warranty. "

Im just copying what he said. Maybe somebody told him something different. I dont know.

I understand. Just that it's dangerous to take the words of a Magazine writer/PR flacky as those of the Company's. Most Manuf. affiliated Publications are subbed out to PR firms.

its not dangerous to copy it, its dangerous to believe it word for word. I dont think its true becuase the solution is to easy and that would mean nissan admits they made a mistake, which i dont think will be happening any time soon.

If you mean track the car, like wot all the time will overheat the oil quickly?

Well you're not being very specific. You can overheat the oil and destroy the engine of just about any factory car given hard enough abusive driving :) If you're actually going to use the car on real tracks or road courses doing real racing, an oil cooler system of some kind is highly recommended. Generally speaking the more you keep the revs up high and the engine under heavy load, and the less airflow you're getting, the more the oil will heat up. A long session at a hard track will almost definitely limp-mode a stock 370Z. Cruising down the highway at illegal speeds and occasionally dropping down a couple of gears to sprint past someone generally won't.

i dont' have this problem anymore but can i ask you guys where to purchase this other brand of oil like RP and etc.. I might just switch mine because right now my dealer changed my oil and used the nissan ester oil.

I would report this oil issues with the Home | National Highway Traffic Safety Administration(NHTSA) | U.S. Department of Transportation this can be a safety issue when on the highway and car goes into limp mode. This may force nissan to do a recall and an investigation on this issue.

Ummm, not on the highway. Won't happen. You have to actually be racing to get limp active.
