Select Your VehicleAuto enthusiasts know that luxury is built into each Lexus, and know that only top quality repair RX300 parts will suffice when repairs are needed.

It's not all the time that you realize that you have to buy a replacement Thermostats to fix your automobile. When your Lexus RX300 was born, it was destined for a person with discerning taste who wants Japanese engineering in their automobile.

Why Thermostats replacement is so important.

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 ideal 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 determined for the engine to achieve the best balance between power, fuel efficiency, and emissions... all thanks to the thermostat.
