You need to change your thermostat in the car.
To change the thermostat on a Kia Sorrento you will first need to make sure the car is completely cool since the thermostat is located near the radiator. Once your car is cooled down, simply unbolt the old thermostat and bolt in the new thermostat. It is that simple, there are no other parts to remove.
