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.

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.
