The Chevrolet Tahoe has a Thermostat which is a component of the engine cooling system and regulates the area temperature of 195-220degrees Fahrenheit. This small, but effective tool consists of a chamber with wax which, when melted or frozen, opens or closes the valve to regulate the flow of the coolant through the radiator. Thus, regulating the engine temperature, the thermostat can maintain its functioning at the top level and avoid constant wear of its components. Thermostats: previous mercury & bimetallic, and the present and future pneumatic-to-digital interface: how integration improved temperature regulation in the past and up to the present.
