Thermostat is a small and often forgotten part of a car. However, it performs an important function by controlling the temperature of the engine coolant valve. Thus, when it stops functioning, the car engine can get overheated and does not work anymore. Thus, once this thermostat begins to wear out, it should be replaced without much delay. The thermostat starts at a closed position when you start the engine to help it reach operating temperature. As coolant temperature rises, it begins to open. The opening allows hot coolant in the engine to flow into the radiator, while the water pump pushes lower-temperature coolant from the radiator into the engine. When the lower temperature coolant reaches the thermostat container, the expanding fluid begins to contract, closing the thermostats valve. During engine operation, though, the thermostat actually never fully closes or opens, but gradually nears either state to control coolant flow, depending on engine operating conditions. This
