Usually not, unless it's faulty. When was the water pump replaced last?

However, the thermo-switch is the radiator that controls the fan is a definite change item at 100K.

Replacing the thermostat and coolant temp sensor at the same time take care of the fault code he's no doubt getting. Otherwise you're guessing, then draining coolant, replacing the other part, refilling and bleeding all over again.

    Replaced thermostat, coolant temp sensor and coolant flange. The car will run great just pushes coolant out the overflow on the recovery tank then overheats.
