One oil cooler is not enough

SunsetZ · 05-10-2014, 09:00 AM

I noticed on GT Academy that Nissan added four openings on the top of the front bumper, that doesn't look good but seeing that the manufacturer went that route says something about it being a good solution.

This.

Any gaps will cause the air to duck around the heat exchanger rather than flow straight.

Staying in the lower gear is surely heating things up too, as you noted.

Chuck's suggestion for a dedicated puller fan idea should certainly help.

Also, you can tune radiator fan duty cycles with uprev to come on full blast earlier -- that will definitely help out.

Unless your oil cooler is mounted that high I don't see how that would help.

They are doing it for a reason. The radiator goes all the way to the top of the bumper. Lower rad temp means lower oil temps and vice versa, it's all interrelated.

OP it sounds like you have done all the right things. I wish you luck.

I too have a 34 row oil coller in a 2009 Z, and at 99 degrees at Sears Point I hit 260*, while using a higher gear did bring temp down some. I did not hit limiter. Also no humidity to speak of.

This is an extreme heat situation, hopefully with these small fixes you will not be plauged again.

Because of how much the vented hood helped with cooling I would bet the engine bay on our cars are a high pressure zone and if thats the case I can't imagine the holes would help flow much without somewhere for the increased air flow to get out of the engine bay. With that said, if you try it please let us know how it works for you.

Cai holes?

It's an oil stabilizer not an oil cooler. Adding an after market oil cooler while keeping the stock oil stabilizer does nothing but cancel each other out. You need to remove the stock on and your temps will drop.

Thanks, as I said above I have the part on order to do just that, fingers crossed.

I have a feeling this is actually heating the oil instead when a separate cooler is installed. I took it off to see if I could just put a return on it and not use that coolant thing, but there needs to be a new threaded fitting made to be able to connect the Setrab directly to the engine. Anyone know if these are available?

I turned the heater to full blast and that helped get some heat off the engine, but in Florida even with the windows down, that is not comfortable. Any ideas on how to have the heat set on max, and get that air directed outside the car instead?

I think you're right about the 13/14 collar. I tracked at Sebring last weekend (and it was HOT). I did 3 30 minutes sessions and only had to lay off towards the last 5-7 minutes of each one. I'm not running an oil cooler at all and have a 2010. I did stay around 240-250 for most of it... I'm gonna grab a 25 row soon.

Dont listen to dicks, any whoo there are few things u can do to get the heat out of the engine bay without wasting too much $, well there are rubber "bushings" that go along the window almost on the top of the engine bay it is there to keep ur hood from vibration when ur going over bumps, if u remove them 3 of them 2 small 1 long they let more air out of the engine.

If u still want more cooling i would suggest removing the under engine cover that will be a huge difference, but has a draw back dont drive at extremely high speeds cuz its letting air under ur car and well its unsafe.

And if you just want to pay 4 something that will work best well i suggest buying a vented hood, bigger radiator, or another cooler.
