Just changed out my trans heater. Now the engine overheats after 3 minutes. 2018 Rubicon unlimited 2.0l turbo

my guess would be a stuck Thermostat/sensor... if it sits for a prolonged time that could be the culprit.

There maybe some soft codes that didn’t throw a CEL. Do you have a way to scan it?
