Genuine Mazda RX-8 Thermostat

The Mazda RX-8 Thermostat controls the flow of coolant in a manner that the rotary engine operates within the power zone but the parts are not exposed to heat stress. The device is engineered around a high-response wax pellet that measures small temperature variations, expands or contracts, and opens or closes its valve within a few seconds to keep the sweet spot of horsepower, clean emissions, and long-term durability. The same calibrated unit may be installed on models from all six production years, 2003 to 2012, which implies that owners of six-speed manuals, four-speed automatics, or any other factory transmission would enjoy the same thermal control. That cross-model fit highlights the fact that Mazda has always been reliable since it did not have to redesign the part to address defects. A Thermostat that works well also enhances fuel efficiency as it allows the engine to warm rapidly, therefore less time is spent in rich start-up mode, which in turn means less load is placed on the cooling pump, and thus less energy is wasted pumping excess coolant. There is also greater safety, because the stable temperatures mean that the viscosity of the oil is always consistent and that it does not soar suddenly, causing dash alerts or limp-home logic. As opposed to older bimetal strips that responded slowly and tended to leak, the contemporary wax pellet fits snugly under vibration and boiling coolant, and enjoys accolades from fast-track drivers on their day of hard driving or highway commuters on their lengthy trips. Checks of the Thermostat on any RX-8 trim require a few minutes and can avoid costly repairs on Mazda engines. The other unique feature is the small size of the housing that fits well around the radiator yet does not bulge into the subframe of the front of the RX-8, which allows the chassis to retain its legendary handling. It is a minor yet important piece of evidence as to why Mazda parts are trusted the world over by owners who attach importance to spirited performance and peace of mind.
