I think even in the warmer parts of the US, for your average commuter that doesn't push the car too hard, they can probably live without the cooler. The temps may jump from time to time to 240 or maybe 250, but probably not enough to hit limp mode by far, and the engine will live plenty long to meet the warranty obligations.

It's pretty insane that i can go from 180 to 250 within 5 minutes. I can only imagine how much quicker it will go up once i start actually driving the car up a mountain.

2009 370Z all stock. Water temps appeared fine the whole time.

Car is going back to the dealer with a "chronic" oil over-heating problem.

Oil temperarature gauge hit 260 with moderate speed on a quiet stretch of road.
I am calling 800-647-7261 right now. I want an oil cooler!

This forum is great. You guys kept me from wasting money on a worthless NISMO radiator cap and even though I have a set of Berk HFCs in the garage with an Invidia cat back and Status-Elite intake on the way, the car will stay stock until Nissan gets the engine heat under control.

Thanks!

The car actually started to smell in the cabin, and my oil temp spiked to 275-285 within 4 minutes of light-spirited driving. It was 70 degrees out and I just had an oil change with the expensive Nissan Ester Oil. It actually took about 40 minutes of light driving along Lake Michigan where the temperature was 56 degrees to cool the thing back down to 200, where it normally is. Man, that's not good at all.

So anyway, she was not aware of this problem, but I guided her to this site! She looked and sounded concerned and appreciated the information. She was going to talk to her engineering department and find out more. The word's getting out. I told her that a lot of us don't want to put on aftermarket kits to fix this because of the warranty. (Those of you who are going to blast me saying that those won't affect the warranty, keep that to yourselves.) We bought the cars not knowing that overheating was going to be an issue. I've owned a lot of brand new Nissan/Infinitis, (my daily driver is an '09 Infiniti FX35.) No overheating on that one. I just said to her, "If you are coming out with this kit, can you please just make it cheaper for those of us who already have bought the car? We had a budget for what we wanted to spend on the vehicle, and didn't plan on spending extra money on a engineering mistake that we weren't aware of." We should all know that cars are not perfect, and there will be some flubs on occasion. I also said, "I can understand if I have a bad power window, or a lock switch that breaks. If my dash lights burn out, I have to have it fixed. No big deal. An overheating engine with light driving is a serious flaw that needs to be fixed ASAP." She was really nice and said she will call me back as soon as she gets any new details on the situation. I'm not happy if we have to pay for this cooler, but if we do, I asked her to tell corporate to make it as cheap as possible. I'm sure they don't want to have to deal with Lemon Law issues. They were very nice though. I hope something's done soon with the warmer temperatures.

Oh, one more thing... I mentioned the 370's TV ad to her. I said, "Do you know the ad? The guy out spinning around and having fun in the car? That's what we bought ours for. To have fun with. To find out the car can't even drive up a steep grade in warm conditions is completely the opposite of what was told to us. We love our cars, but just wish we didn't have this major problem. Please help us." She couldn't have been nicer.

Thoughts?
