What happens when the radiator thermostat gets stuck?
Thermostats occasionally get “stuck shut” which cuts off the cooling capacity of the radiator, at least partially. This often occurs after an engine has overheated for some other reason, such as when the water pump fails, or if a large coolant leak develops. For this reason, car makers usually place the thermostat in an accessible position.
