Help?
Live in Texas and the guy I bought the jeep from was in Colorado. He only has an aftermarket fan on the radiator so naturally it keeps my jeep pretty hot because how hot it is here. Well anyway it seems to turn on around 235 or so, I bought a new stock fan from a 99 and im wondering how I get it to turn on at about 195? He has it hooked up to that sender thing which goes inside my radiator tube to check the coolant temp. But couldn't I just hook up the other fan to the stock wires and it should come on at 195??

What did he use? Looks like a water heater thermostat, lol. Also looks like there is a temp adjustment on the front of it?
I think I'd be inclined to put the stock mechanical fan back, I'm not convinced the electric aux fans move as much air. I imagine you could wire it back to the stock temp switch and perhaps replace the switch with one that trips at 180-190. (I think the factory setting is higher than 190, but don't really recall)

Well....you live in a hot part of the country and that factory aux fan is small, not meant for main cooling duty. Two undersized fans is still not as good as one OEM mechanical fan and one OEM Aux fan.... and that OEM setup is marginal to begin with.
However if you really want to do it that way, the simple thing would be to re-use the existing coolant temp switch to power the new fan, perhaps replacing it with one that kicks in at a lower temp. Might look at the Taurus fan swaps if you want to remain all electric.
