2015 Silverado 1500 LTZ 6.2L Last month I noticed my temperature gauge was pegged at an 160 and the fans were running at a very high rate while driving. When I turned off the ignition and removed the keys, they kept running at a high rate for around 2 minutes. I read in some forums and they said it was probably the temperature sensor. I replaced the sensor. It still did it for another day and stopped. Yesterday, the problem started again. I did some more research and found that it could be a thermostat stuck open. I just replaced the thermostat. The truck is still doing it. What else could this be?
