The fan actually sort of gets in the way of cooling when hauling down the highway, since at speed there's no need for a fan to pull air through the radiator then. Nature takes care of forcing air through at that point, which is why the fan clutch in theory is a great idea, letting the fan slip then.Agreed. He seems to have plenty of cooling around town but when he is cranking 3500 rpm for an extended time down the interstate his temps are climbing. If he has a thermal fan clutch it should be grabbing when the temps get above 180 behind the radiator....correct?
With a 160 thermostat he is making his operating range much larger and open for larger temperature swings. Is a 30 degree swing just normal for this set up? Or should the fan and clutch be holding the temp lower?
The fan is supposed to lock up and drive directly when the car is at lower rpm/idling, since then the fan is the only thing moving air through the radiator.
