Well designed, right?

Recurring heating problems on a Toyota Supra Mkii

Broken thermostat

The concept is easy, if the thermostat that regulates the temperature does not really measure the temperature of the water circuit, the entire circuit is affected. Even if the thermostat of this Toyota Supra Mkii still does not work correctly, the heating will work normally. Because the natural temperature of the engine will gradually increase, so will the cooling system at the same time, even without a thermostat. The only concern is that you will be unable to control the heat emitted.
