Is there or is there not a problem with the oil cooler?
 

Hey everyone...
My first post here....Is this true about Nissan working on upgrading the oil cooler because of poor early track performanceshttp://img.photobucket.com/albums/v2...Z/question.gif

ur almost there. this car is in need of an oil cooler because temps rise too high with hard driving. so if ur a big track guy, then an oil cooler is a must. otherwise, ive driven mine pretty hard here and there and i also run on the highway all the time with no problems. most likely in future models, nissan will provide an oil cooler in the sports package. right now u can get one from nissan thru nismo. either that or there are several aftermarket options

There is a nismo one?

As of this date, I'm pretty sure that Nissan via NISMO does NOT offer oil coolers for sale to the public. I think this would be the best solution for those concerned about warranty. But I can find no listing of it as an option anywhere, including Nissan Japan's website where they show all the 370z NISMO S-Tune optional parts. Many of these parts are not yet available in the US, but no oil cooler is listed.

Nissan knows this is an issue for the track, but not the street. Car and Driver stated their test vehicle in their original test review had an oil cooler and diff cooler installed, as did other early cars given to the press (Edmunds points this out too). But production models do not have them yet and I wouldn't count on it as 2010 standard feature. So the only current solution is the aftermarket.

Which begs the question -- Which oil cooler did Nissan install on these test vehicles?

^Good question.

It was Edmunds that said you can get 'em from NISMO. But I'm not sure if this is really correct. This is a picture taken from the Edmunds website, it shows part of one of the coolers in question on their test car. Certainly doesn't look like a stock OEM install to me...

^ that looks like an oil cooler installation for the differential to me.

any cooler with decent capacity should do the trick guys.

This is the real question whether you get that particular cooler or not, it'll give the requisite sizing, best pacement, etc. needed.

I'm still wondering what people in the really hot areas (like here in phoenix) will see in the summer. I mean, when it's 120 outside, and you're sitting in bumper-to-bumper traffic with the AC cranked, will it be a problem? I'm not totally convinced that it will be a problem, but I will be keeping an eye out.

Wouldn't the coolant moving thru the A/C radiator, help cool the engine radiator? What I'm trying to say-Coldness from the A/C radiator, passed on, by air flow, to the engine radiator!

Just my 2 cents-But with this engine having heating problems, I think it would be foolish not to install an oil cooler! Track or not!

^ naw, if you want to lower your engine temp, you have to turn the AC off, or even turn the heat on.

Shouldnt be a problem ^ I have G37s and here in south Texas we got up to 107F and I drove all day mixed highway and bumber to bumber city traffic and neither the car or my self broke a sweat, I was sitting nice and cool inside! Limo tint does help tho.

Yes, the press test cars had both differential coolers and oil coolers. Makes one wonder what's up with the differntial as well. Hmmm...

If you arent going to track the car, you don't need a cooler. You can't push the car hard enough on the streets to get it to any sort of concerning temperature. I don't think that hot days will make a difference.. Guys that live in warmer temperature climates and dont track the car - be patient and don't waste money until someone actually confirms that you need a cooler. Its not just money either... installing a cooler when you don't need it just adds things that can go wrong...rock through the core, loose fitting - boom and your engine wont be covered under warranty.

Agreed.

so if i'm just driving like normal it will not be a problem but if i take it to the tracks, it will?

Check out this thread I just found. Kinda funny, because they're discussing travisjb's thread on tracking the 370 and his oil temp issues.

New 370Z Overheating with mild track time.... - Bob Is The Oil Guy

That depends on your definition of 'funny' :drama: After all this, will anyone else dare try their 370Z at the track?

DAD dissapointed. the "cooland that goes through the A/c Rad. is really quite hot that is where the heat is released from the system. Like the coils on the back of your fridge. lol

Sure, after it's broken in, the oil is switched out for a quality ester-based synthetic, and a good oil cooler is installed. Why not?

My son in laws car(Saturn)would over heat, turn on the A/C, the engine would cool off!

200 miles on the car, and he takes it to the track. The engine is no way broke in! That's foolish!

The rule of thumb is that if your stuck in crawling traffic...you shut off the A/C & radio & roll down the windows!
Turning on the A/C!!!! unreal!:nutswinger::wtf2::rofl2:

Aparently on Saturen they do not obey the laws of thermaodynamics. :p

This thread is tittering on the edge of a cliff. Lets keep it on subject. Its a good read for those who are considering the cooler.

You don't need one for daily driving or sitting in traffic.

You will need one for track sessions.
