Someone please educate me on this one, as I‘ve never understood the logic of having the fan come on a a higher temp than the engine thermostat. Although I have read of custom radiator companies making this very recommendation.
I don’t want the radiator dumping coolant into the engine that is hotter than the engine - that make no sense to me. I run a 180 degree thermostat (easy fellers, remember I’m not running a 4.0
) and a 170 fan controller - which works very well for me.
I run a variable speed fan which does usually run at low speed, but rarely at full speed. But it’s certainly not a daily driver, so I’m not worried about fan life.
So help a guy out: What am I missing here?
