How long does a car thermostat last?
The service life of the thermostat is about 3 years, and the general replacement cycle is 50,000 to 60,000 kilometers. Based on the average annual driving of a family car of 20,000 kilometers, three years is the approximate service life of the thermostat.
Most cars basically use water-cooled engines, relying on antifreeze to continuously circulate in the engine to remove heat. The antifreeze in the engine has two circulation paths, one is a large circulation and the other is a small circulation.
When a freshly started engine has not reached normal operating temperature, a small amount of antifreeze will circulate in the engine. At this time, the antifreeze will not dissipate heat through the radiator tank, which is conducive to the rapid heating of the engine.
Antifreeze circulates heavily when the engine reaches normal operating temperature. At this time, the antifreeze needs to dissipate heat
through the radiator tank to keep the engine temperature within the normal range. The thermostat adjusts the circulation path of the antifreeze, and the thermostat can switch the circulation path of the antifreeze. If the thermostat is ready, the antifreeze may always be circulating in greater or lesser ways.
If the antifreeze keeps circulating in small quantities, the engine temperature may be too high. The engine temperature will exceed normal operating temperature because the antifreeze has been circulating a small amount and is not cooling through the radiator tank. Some high-end cars use electronic thermostats, which respond faster and adjust more accurately.
How long does it take for a thermostat to fail?
The thermostat is a relatively important part of the vehicle. It can adjust the heat dissipation capacity of the water tank of the car. If the thermostat is damaged, the vehicle will not work normally.
How long does it usually take for the thermostat to fail?
In the case of normal use of the vehicle, the service life of the thermostat of the vehicle is about 50,000 kilometers. If the annual driving mileage is 10,000 kilometers, then the thermostat can be used for 5 years. If the annual driving mileage is 20,000 kilometers, then The thermostat lasts for 2.5 years.
The main function of the thermostat is to adjust the circulation of the coolant of the vehicle. When the thermostat of the vehicle is turned on, the coolant is in the large circulation mode. If the thermostat of the vehicle is closed, the coolant is in the small circulation mode. Therefore, the function of the thermostat is very important. If there is a problem with the thermostat, the owner needs to replace it in time.
If the thermostat of the vehicle is damaged, the combustion of the mixture will be incomplete, the vehicle will consume a lot of fuel, and it will also increase the wear and tear of the engine, which seriously affects the life of the engine.
