Did you install an AC Delco 131-158 thermostat?
Did you burp the cooling system?

Why does it make a difference, thermostats all work the same?

It’s been proven time and time again , the other brands don’t open in the time frame the computer is looking for, causing problems like this.

How do you burp the system,

Would this cause my temperature sensor to stop sending signals to both the digital and analog gauge to read --- and zero?
