2005 Sorento ran hot

What is your question?

My wife was about a 100 away from Home said the car is running hot. They got where they were going put water in radiator after it cooled down crank car and temp started up. A mechanic help them the radiator was fulll and he unplug a sensor that let the radiator fan run all the time. Temp went down and they made it home. The mechanic said it was problem the thermostat. Next day I change thermostat,new antifreeze and let it warm up and it got hot again unplug the sensor and temp went back down to normal. So what could it be?

What makes this problem better or worse?

Unplug the sensor that makes fan run all the time

Hello, You could have a bad accessory/air conditioning condenser fan, so make sure they are both running when the engine gets hot. If the fan is not turning on when the engine gets hot, that calls for concern over the powertrain control module (PCM) activating the fan, or the cooling fan controller (if equipped). The issue I have with that theory is that unplugging the engine coolant temperature sensor would not necessarily work if the PCM were functioning incorrectly. This will need some testing to ensure it is not an electronic issue. If it is a mechanical issues, knowing when it overheats and gets cool is a big help to diagnosis.
