COOLING SYSTEM HELP!

1996 Saturn SL1 • 120,000 miles

Im totally lost on this one. I have a 96 Saturn SL1 1.9 Vin 8, the surge tank will "over flow" before it hits "normal" operating temp. For fun I wanted to see if the radiator fan turns on at operating temp, but it doesnt and the needle keeps rising. Because it is a GM vehicle, I figured that it could need to go up alittle more from middle to turn on. Again, no fan. This point I swapped thermostat and waterpump, swapped a surge tank cap for a dealer one, checked radiator hoses, relays and fuses, checked PSI rating, heater core hoses, ECT Sensor. No leaks, good psi (BTW 18psi), all hoses "luke warm" before the car decides to boil over at me, and no electrical short. Now I can leave the ECT unplugged to get my fan to run constant and my gauge in the dash not to work, but that would suck in the winter.

Plz help, I'm totally lost!

Oh. Good to know for future reference! The sensor color is white, as I bought another one because they are inexpensive, plus I learned that not every new part is going to work.

Alright see if the fan comes on at 222-226 degrees and see where the temp gauge reads when the fan comes on. Let me know what you find.
