The function and purpose of Thermostats.

Your car or truck has a liquid-cooled engine, and the device that controls the flow of coolant so that the engine can remain cool is your thermostat. On start-up, the thermostat remains closed; bypassing the flow of coolant through your radiator. This gets the coolant hot so that the engine warms up. Once it reaches an optimal operating temperature, your Lexus RX300 thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your Lexus RX300 engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.
