Mazda RX-3 Thermostats

Keeping your RX-3 in top shape is your top priority.

Select Your VehicleThe vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles these days. When your Mazda RX-3 was born, it was destined for a person with discerning taste who wants economical pricing in their automobile. You picked your RX-3 because its best-in-class value and long-lasting quality struck a chord inside you; so why would you be okay with second best when it comes to superior quality auto parts? Your Mazda dealership isn't the only place to locate trusted replacement parts for your RX-3.

What Thermostats does for your vehicle.

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; shutting off access to the radiator. This gets the coolant hot so that the engine warms up. Once it reaches an optimal operating temperature, your Mazda RX-3 thermostat responds by directing coolant to the radiator. Now your coolant gets cooled as it recirculates through your Mazda RX-3 engine; keeping it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.
