Why you drive your RX-4.

The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs on the road today. Auto enthusiasts appreciate the a sporty attitude built into each Mazda, and understand that only the highest quality replacement RX-4 parts will suffice when repairs are needed. Your Mazda dealership isn't the only place to locate genuine or original equipment quality parts to repair your RX-4. Mazda vehicle owners have grown accustomed to a certain level of best-in-class value when driving their RX-4 around town.

The function and purpose of Thermostats.

Your car or truck uses liquid coolant to maintain a constant temperature in the 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 cycles the coolant through the engine block and gets it hot. Once it reaches the right temperature, your Mazda RX-4 thermostat responds by directing coolant to the radiator. Now your coolant gets cooled as it recirculates through your Mazda RX-4 engine; keeping it within a specific range of temperatures that are ideal for engine performance... all thanks to the thermostat.

Good products, great prices, the best people.
