I have a 2012 Chevy Cruze 1.4t that I just replaced the motor with a used motor because the head gasket went on the original one. I heard the motor run and scanned the computer and everything seemed good. I don’t think there’s anything wrong with that. Im having a reoccurring issue that started before I did the swap. I’m getting a COL for bank 1 lean, coolant thermostat, high idle, coolant system performance, and coolant flow low/performance. Also I’m getting the “A/C off due to high temperatures” on the dash. I was told before online to replace the coolant sensor on the radiator and I did that. Any suggestions?
