Genuine Mazda Protege5 Thermostat

The Mazda Protege5 Thermostat is the microscopic yet essential valve that enables the sporty hatchback to heat up fast, followed by holding it in the sweet spot where it is in power, economy, and quality. Sealed in a small capsule within the radiator outlet, the wax-filled capsule heats up, causing the plunger to open when the coolant hits the factory set point, another physical magic trick that has gained a reputation of never-quit reliability even after years of vibration and red lights. Mazda decided to keep the design the same model year after model year, thus any owner of a car in the 1999-2003 Protege5 with an LX or ES trim and having either the 1.6 liter or 2.0 liter engine can install a direct-fit unit without fear of calibration errors. The device can reduce cold-start fuel use by shutting off the coolant flow until the block is hot enough, activating the cabin heater earlier when it is colder, and protecting pistons against detonation when it is gridlock time in summer. This Mazda reliability is an assurance of a reduced number of unforeseen temperature spikes on the road. More safety is provided by the capability of the Thermostat to avoid a boil-over that will leave the driver stuck. The fact that the temperatures are quite stable and thus allow the engaging suspension to be repeatable on spirited drives, and that the oil viscosity is maintained on quick warm-up to enable the five-speed manual as well as the four-speed automatic to make the shifts smooth, are also valued by Mazda enthusiasts. This mechanical hero operates without sensors or programs, unlike electronic or pneumatic climate controls elsewhere, which means that there are no glitches with blown fuses or moisture. To the shoppers who visit the shelves of parts, the clean wax pellet process, perfect fitment throughout the Protege5 line and the record history make this Thermostat stand out among competitors.
