| to operate in the manner that it does? It makes perfect sense why nissan designed the gauge to work as it does: there is a nominal range of acceptable engine temperature at which it is safe to operate the vehicle. As I responded to you in the post last night, the electric fan simply is not going to flow as much as the OEM mechanical fan will. I've never told anyone or implied that it does either. This will invariably cause the system to run slightly warmer in some cases and will be exacerbated if there are other issues in the system. The point I am making here is that you are overlooking the dynamics associated with the cooling system: it appears that you are looking at it from a 2-dimensional perspective rather than from the rather complex nature of the system as a whole. Consider this: the engine may operate a few degrees warmer with an electric fan dependent on the operating conditions, the additional heat will tend to slightly reduce performance of the engine, however, don't overlook the fact that you no longer have a mechanical fan sucking power directly off the crank, of which is "giving back" power to you. You nor I can say exactly which aspect has a greater effect. What I can say with a good deal of certainty is that DAYTONAZ TT is operating in rather high ambient temperatures and the stock gauge is telling him that it is well within acceptable operating temperatures. I'm sure a techtom or conzult will tell you that it is running slightly warmer than an OE mechanical fan setup: I cannot argue with you there - that is a simple case of flowrate capacities, but I can argue that your point is moot considering the fact that it is still within acceptable operating temperatures.
