I found this :

The CSF Radiator/Condenser combo

CSF Aluminum Radiator Condenser Combo

CSF 370Z Radiators NOW AVAILABLE @ Z1 Motorsports! - Nissan 370Z Forum

My car heat up alot especially in traffic during summer (mostly) which affected the performance (such as idle stability , AC cooling , throttle uneven/crazy response ...)

In UAE, temperature sometimes reach 49C = 120F .

Has anyone used it ? would this thicker radiator solve my issue ?

thanks

 

Start with the 25 row Z1 oil cooler. WIth thermostatic plate.
See if that helps first.

 

How high is it getting?

 

I thought of the oil cooler first , but reducing the water heat is more efficiency , i would start with oil cooler if it help.

Do you mean temperature gauge ? if this what you mean mostly the gauge stable with very slight difference if the car stopped for long time in the traffic.

 

That would be your car going in limp mode, due to high oil temps.

 

What i know about limp mode is engine rpm is limited and this happen as you said due the high oil temps .
What i am expericing is the car pulling through while trying to stop , it accelerate by itself or something , then when I start driving again it jumped first then it become normal ! (This ONLY when the engine gets too hot).
Its really hard to explain but i tried my best. You can call me crazy but this is what's happening to me since day one i bought this car.

 

That's more of your car needing to be fixed by the dealer. There is a TSB for that. Read this thread it should tell you what you want to know. That happens to me too when it gets real hot. But I have a custom tune in my car and I don't want to loose it, so I just have to live with it.

 

Thats why we need to fix the high temp. issue.

 

It's more the way the ECU was programmed than the heat. Unless your racing or your car goes into limp mode you don't have that much of a problem with the car overheating. I'm not saying you won't benefit from the coolers (oil and water) but the big issue is the ECU. Before you go buy the coolers, which ever one you are thinking of, get the TSB done on the car first.

Other than that go for the oil cooler.

 

I thought the custom tune will fix ECU problem , anyway I wiil see what can I do.
Thnks

 

Come to think of it I would think so too. But I guess just the parameters of the delivery are adjusted not when??? Or it's really a TSB about the TCU so it changes when it disengages the clutch packs??? I never really read up on the TSB, I just know that a lot of people had the same issue as us.
