1.4 Turbo. I have a 2014 Cruze LT. Figured it was roughly the same issue as talked about in this thread. I replaced both sensors, coolant reservoir given i couldnt get a cap separate, and thermostat. Also replaced two of the 5 fan relays since the other three are not available anywhere. Fan didnt come on till 230 at first. However it is coming on A little sooner now but idle temp at 203 presently after a half hour. Was up to 230, dropped to 225, then fan came on at 228, then dropped to 220, then fan came on at 226 and so on so far. Presently in between 198 and 215. That was without AC on. Now running AC. Did fine stayed in the 198 to 215 range. Then turned off AC. Fan went back to coming on right at 230. Temps staying between 220 and 230. But so far no high speed fan mode. After the thermostat and sensors but prior to the two relays and coolant resevoir with new cap, its doing better but still not as it should be.you should start your own thread. Also what engine do you have?
