What happens when a thermostat goes bad?

A faulty thermostat will result in strange temperature changes during engine operation. In this case, the thermostat will not get stuck in one position, but there will still be false readings causing control issues. The engine temperature will change unpredictably and the radiator coolant will not flow normally.Other broader symptoms that you might experience if you have a bad thermostat might be: Temperature gauge reads lower or higher temperature than usual The vehicle’s head does not work Your automatic transmission is not able to shift to higher gears due to the lack of power. A significant drop in the fuel economy. Temperature warning light illuminating on the vehicle’s dashboard A failure in the head gasket More items...
