Thermostats are more likely to stop working much earlier than a decade. However, most car experts recommend car thermostat replacement after 10 years. There is not a set time for the car radiator to stop working. How long does a car radiator thermostat last? Let’s find out how long a thermostat lasts along with the signs of a faulty car thermostat. However, you need to keep an eye on its function to ensure optimum performance of your vehicle. There is not an exact mileage at which a car thermostat fails. This brings us to an important question – how long does a car radiator thermostat last and when should you replace it? Since the thermostat keeps working for as long as the car is on, it can wear out eventually. It is a metal valve that opens and closes based on the temperature and determines the behaviour of the coolant. Finally, the engine is checked for leaks.Every vehicle has a thermostat that monitors and regulates the temperature of the coolant in your car’s engine. This will confirm the thermostat is open. The car engine is run until the normal operating temperature is reached, and while taking precautions with the hot coolant, the coolant level is rechecked while confirming there is flow through the radiator - either visually or with an infrared temperature gun.The cooling system is refilled with the appropriate coolant type and the system is fully bled of all air.The thermostat housing bolts are tightened to original equipment manufacturer (OEM) specifications using a calibrated inch-pound torque wrench.A new gasket is applied and the thermostat is re-installed in the correct orientation and with the temperature sensing cylinder facing downward towards the engine. All mounting surfaces on the thermostat housing are cleaned of old gasket material.Note that some cars have more than one cooling system thermostat and both might need replacement. The thermostat housing is removed and the thermostat and gasket are extracted.Once the engine is completely cold, the radiator cap is loosened and enough coolant is drained from the radiator so the coolant level is below the thermostat housing.
How do mechanics replace the engine cooling system thermostat?

Therefore, if the cooling system is already open for major repairs, such as water pump or radiator replacement, it is recommended to install a new thermostat simply as insurance against future breakdown. Your dash-mounted temperature gauge will notify you of this malfunction. Thermostats can get sticky, causing the engine temperature to stray from the optimal range.
