I didn this conversion a few years ago. The GDI never gets above 190 with the stock flex fan so I never needed to put the electric fan in. I just read an article about the coolant sensor that goes in the thermostat housing adjusts the fuel mixture. Is that right? I am still running the 87 thermo housing. I never reinstalled the themp sensor. Never needed to. My Jeep runs very rich and has idle issues. I just wanteed to know if there were other fucntions of this temp sensor other than turning on the electric fan.
