Everyone with oil temp issues

rackley

Something that has been bothering me lately:

We have been seeing high oil temps. Nissan included an oil cooler with the preview cars. We "know" high oil temps are a problem. Nissan is coming out with an oil cooler. There are oil cooling kits already on the market. Most people are aware of the oil temp issues.

However, Nissan also included a differential cooler on the preview cars. We don't have an oil temp gauge for the differential oil. If Nissan has data that we don't have (and they obviously do, otherwise they would not have included the oil cooler on the preview cars) it suggests that the differential oil is also likely experiencing undiagnosed/unseen temperature problems as well.

There is very little discussion/data about the differential temps, but Nissan obviously thought there might be a temp problem there, otherwise why would they include a differential cooler? I'm starting to think this may be the underwater part of the cooling iceberg - a potentially big problem, but completely unseen at this point in time.

Nissan did exactly the same thing when they introduced the 2003 350Z. A differential cooler was installed in their introduction test car to the media and others. The reason: not to overheat and stress out the stock VLSD and show it's inherent weakness with continuous tracking.


Since I believe the 370z's differential is the same as the past 350, the only reason for the diff cooler install in the test car is to prevent the stock VLSD from crapping out on the track test.

Yes, the Viscous LSD turns itself into an open diff when it overheats ... and it doesn't take much to make it do that.
