so I was working on a 04 kia spectra today. We replaced the radiator due to two large holes in the bellast. so after the rad was done I added some new coolant and cleaned my mess ran the car with the cap off to bleed any air in the system. so after I drove the car and during letting the car warm up in the shop the temp syated under half on the needle so I drove the car after a min or so the temp started to climb so I drove back to the shop and checked for the fans and they were both on full blast and the lower hose was colder than the top (top was 120 and the bottom was at 90) so I told the SM to get me a new thermostat to remove that from the head games and once instaled I did the same thing and during the test drive the temp climed again an fans wer on full blast, acoding to the wiring diagram the ECT contols the fans and the gauge the head never got hotter than 150-160 the top hose was 120 and lower 90 the head at the ECT was 180-190 but the gauge was all the way hot. to me the engine was good the thermostat was a 190 deg and everything checked out fine with the engine temp so is my assumation of a bad ECT correct?
