If the car thermostat is bad, it won’t allow coolant from flowing into the engine, which ultimately causes the car to overheat. So when this happens one of the possible causes is a broken thermostat.
The reason why running your car without a thermostat won’t cause it to overheat is because it doesn’t regulate the temperature of the coolant. Instead, it only affects the flow of the coolant. Running the car without a thermostat means coolant will continuously flow through the engine in quantities larger than needed.
