Oil Cooler install solves the problem?

I know this is mundane but I really haven't heard any feedback from anyone after their oil cooler installs. Does this in fact solve the overheating problem in all situations?

I'm posing in the DIY section a request for someone to outline how they did it. It's getting warmer here in Chicago and this problem will become a reality for me soon.

Yes it works great. I track tested it today. It handled session after session with no over heating. I mean totally flogging the car.

We tested Technosqaures oil cooler kit on 370z.com with good results, the oil temp never exceeded 250 degrees.

I wonder if there isn't a less dramatic way to keep the oil cool. Here's my point: Nissan has done everything they can to obscure everything mechanical from view under the hood. (I mean, the battery's concealed? The brake reservoir is concealed? Why was that necessary?) There are more extraneous covers under the hood than there are moving parts! The result is that you can't get much airflow around the engine.

It seems to me that a thoughtful elimination of "beauty covers" under the hood would both save weight AND make the engine run cooler. Has anyone done this?

I removed the engine cover, because it's clearly all beauty and traps heat. However, for now I've left the others (batt/brake). I just haven't had time to really analyze the situation with them. They're part of how Nissan has insulated the upper engine bay when the hood is down, I guess to keep dirt/rain out, and to keep hot air from blowing out over the windshield too much and fogging things up? I don't know. I want to remove them, but I guess I need to go stare at the situation more before I do.

But in any case, they're not going to make enough difference to solve this problem with oil temps.

I'm not seeing what function relevance of all those plastic covers either other than cosmetic. What will manufacturers do in the future? Seal off the whole engine compartment and have a few holes for fluid fills and dip sticks. I'll bet they've thought about it.

Have you seen under the hood of a Cayman? Porsche is already doing it!

It helps isolate the heat of the engine bay from the battery and brake fluid. Not much, but it does. Many cars have this, including my Mercedes E320. The only difference is with the Mercedes it has seals and the hood acts as the cover, so it's not as obvious. But it still isolates the hot engine compartment from the brake systems/battery (or in the case of the Mercedes, the electronics - which are put where our batteries are in the Z). I'd bet it reduces temps in these areas at least 10-20*F. Cooking your brake fluid is not a good thing, trust me.. I know..

I popped plastic covers and looked again. From what I could see those compartments are sealed fairly well with sheet metal forming the sides and bottom. I did see what appeared to be a drain hole. So I guess it was Nissan's intention to seal them off rather than simply drop a plastic cover on top. Ok +1. Still seems like you'd get heat build up. I could be a geek and measure inside vs. outside temps.

No it does not. I just tracked my car Monday at Thunderhill, Willows, CA and I have and oil cooler (exactly like Modshack's build) It was on a Cold day ~50 degrees and not even after 15 mins in the first session the car not only crap out by putting it in a limp mode, it completely shut down and won't start up before oil temp even reached past 220 degrees. I had to tow the car all the way back home as I tried everything to start it up. Plugged a diagnostic tool in, no error code. The yellow service required light went on when it happened but afterwards when i try restarting the car it just kept spitting when I cranked the car. I spent the whole day dry cranking the car to air out the fuel from the flooded engine, no luck, the car didn't recover till 2 days later. So, I really don't know what my oil cooler did for me. Any advise? I've heard some people don't even get put into limp mode at 240 degrees. Astor me, I didn't even get a limp mode, all I got was an improper shut down. The left LCD started flickering and it was almost like Fast and Furious 2 when the skyline got shot with a Emp electric gun. =\

What size is your core? For the track you need a pretty big core.

It's a small one, I forgot but it's like a 13" x 7" or something like that. There was another guy tracking there running a lot cooler oil 185 degrees. I'm still surprised it shut down at 220 degrees.

Are you sure it was an oil issue and not fuel starvation?
What level of gas did you have?
