Running 50/50 coolant/water mix. No water wetter. I plan on adding that this weekend, just to see what it does. Stock radiator, stock fan shroud, stock clutch fan, big setrab oil cooler.
Water temps at the top hose is going to be a few degrees hotter than the factory location mid-circuit.
With a normal thermostat, I'm staying around 85 now that it's warmed up outside, read at the factory sensor. It'll get hotter as I beat on it. Clutch fan, copper koyo.
My brother's car has Altima fans, copper koyo, and Nismo thermostat. That car barely makes 75* in-town. I don't think I've ever seen it over about 88* when it actually had water in it.
