Why don't plate coolers have a thermostat?

I think some people just don't opt for it -- adds a good bit to the cost. Either that or the ones they are getting are too cold and not keeping it around the ideal temp when winter rolls around.

Allegedly the block off plate works well enough to help the oil warm up in the winter time... still I'm skeptical. It's just better to have a decent thermostat on it.

Also, I'd say only about half of the people who buy the oil cooler have a clear idea what the optimal range of oil temps is -- 180*F - 220*F, as noted by Import Convert, is spot on. I think a lot of folks just assume "cooler is better", which it's not, unless you are sailing past 240* F of course...

You can run a little cooler and a good bit hotter on modern oils, but something in the 200*F +/- 20 ball park is ideal, especially when flogging it.

If limp mode kicks in at 280* F, that's a bit high. Hopefully it kicks on at 260* -- thankfully I've never had it happen.

"Thank you for contacting Nissan North America, Inc. and allowing us the opportunity to be of assistance.

An oil cooler is not necessary for normal and lawful operation of the vehicle on city streets and highways. The addition of an oil cooler would have unnecessarily raised the price of the car and potentially moved it out of the reach of some customers.

Value has been a core principle of the Z car since the original 240Z, and we choose to uphold this core principle by not adding features at additional cost that are unnecessary for normal vehicle operation.

For those individuals who choose to drive their vehicle on a race track under extreme conditions, the oil cooler is available as an aftersales accessory item.

It's not necessary for normal and lawful street driving and they left it off to provide better value... But they're putting it on the 2012.

Sounds to me like a boiler-plate response to the ongoing question that hasn't been updated to have a little song-and-dance about the 2012. :ugh2:

just get an AM oil cooler and just relax.. lol

What kind of abuse do you need an oil cooler for? Running the track for 2+ hours in the desert? If you live in a moderate climate could you probably get away without one even under long hours of racing?

no you couldn't. for ANY HPDE event, IMO, an oil cooler, (along with brake lines/fluids/pads), is absolutely necessary.

qft

No. More like 3-5 minutes on a track in a moderate climate.

Not a chance, just stay off the track.

I also got a reply from Nissan after asking them why the car suddenly needed an oil cooler and if I could add one to my car without voiding the warranty...I got a COMPLETELY different response.

"Thank you for taking the time to contact Nissan North America, Inc. and share your valuable insight with us.

Nissan does not recommend any modifications on your vehicle from the original manufacturing equipment as this may affect the terms and conditions of your warranty.

Omg
 

Do we really need yet another fracking oil cooler thread? I read C&D's Best Handling Car Under $40,000 article last week and was like, what's wrong with these yahoo's at C&D. Do they not know about the $500 OEM cooler? Doesn't everyone by now know that if you're among the 10% who track this car it's required, but it's not for 90% of the rest of the population? GEEZ.

I'd say Nissan originally thought people would be smart enough to read and figure this stuff out. But since this issue just won't go away because people are being so ignorant about it, they were like, F-it, just add the fracking thing and let's be done with it.

Now if Nissan would have just fixed the major brake fade and gave it a telescoping steering wheel for 2012, C&D would move it from 4th place to first place. Why aren't people on here bitching so much about the brake fade if it's such an issue?

Bc of the same reason you pointed.. 90% of the people who own a Z does not experience brake fade. If you are tracking then besides an oil cooler, you need pads, fluids and lines. I agree on the telescopic steering wheel though.

C&D had the Nismo pads on and still had issues. So do those pads suck too? Or as you are saying, it's just a matter of better lines and better fluid? I'm no brake expert so someone fill me in, please. But if it's just a matter of better lines (what, bigger diameter???) and a different fluid (different how??), that seems like an incredibly easy change for Nissan to just make standard. Adding an oil cooler adds material and labor costs to production. Changing the brake lines and fluids only adds material cost, not labor.

Adding a telescope wheel is probably a big engineering change which would effect many other components, so that's another matter.

Because if you track, you know you have to fix these problems, and if you don't have an oil cooler, you probably aren't going to get enough laps in to get to the point where you will have brake issues.

what is really interesting is that w0ady tracks his G37 pretty hard and has no brake or oil cooling issues.
