I just replaced the thermostat in my 5.4 because it was running too cold and throwing a code. Now it overheats and shuts down.
I tried burping the system to get air out, and the truck wouldn’t overheat with the overflow cap off, but as soon as I put the cap back on it overheated.
I’m lost, thinking maybe I got a bad thermostat.
