Yes, kind of... it popped up "Engine Hot, A/C Turned Off" on my way home from church the other night.
No CEL but I had to clear a pending P0128 Thermostat malfunction code in order to get the message to go away and the cooling fans to turn off.
I checked everything and the truck wasn't overheating... coolant level was good and the OBD2 data showed 142°.
Evidently GM, in all of their infinite wisdom, decided that if your vehicle takes too long to get up to operating temperature they will make the DIC tell you that your truck is overheating... lol
After the restrictor install the truck gets up to 192°- 194° just like before and no more issues.
Good info. And further evidence that the vital gauges aren't for reporting actual stats. The PCM can make them do whatever it's programmed to do. ******* them out to draw attention and/or displaying urgent warnings in the DIC are just entry-level measures enabling us to not have to pay attention when we drive. Next level is side warning detection, then cameras all around, then steering that corrects when you drift, then cars that park themselves...
MAKE AMERICA DRIVE AGAIN!!!
