I also added an inline temperature sensor and digital indication on the dash. It is installed in the feed line to the radiator hose from the engine. What I see is that the fan kicks on about 203° F and shuts off about 195°. That is all at 2 bars. I see 3 bars when temp gets up to about 220°. Max I have seen is 234° and at 4 bars. This indicator was added when the 2nd fan was installed. But, I drove the same trails a year later, and gathered these temperature and bar data points. But, the high temps were dramatically decreased with the new fan.
