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!
