You purchased your RX-4 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 great quality auto parts?

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; shutting off access to the radiator. This cycles the coolant through the engine block and gets it hot. Once it reaches the right temperature, your Mazda RX-4 thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your Mazda RX-4 engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.

Top-tier components, prices that won't break your bank, knowledgeable professionals.

Don't let a Thermostats repair spell the end of your car, truck, or SUV, and don't gamble with its condition by buying anything but the best replacement parts.
