So I was getting on the interstate to head home the cars temp gauge went to cold then ENGINE HOT A/C OFF and the rad fans full blast probably the sensor right? Hopefully lol
I should have stated that if engine temp was not overheated, then could be stuck open. I had a chevy truck that would do that and show same indications and it was thermostat stuck open, or opening slowly. There is an algorithm for these vehicles that the computer looks at OAT and how long it is taking the engine to warm up and if not within a specified time, it errors on the side of caution and thinks the engine is overheating.partially closed??
