Beck/Arnley Engine Coolant Thermostat P/N:143-0774
Beck/Arnley 143-0724 thermostat for the 2019 Mazda CX-5 4-cylinder 2.2L and other vehicles controls coolant flow so the engine reaches and holds its operating temperature. As an engine coolant thermostat, it stays closed while the engine warms up, then opens to send coolant through the radiator.
A thermostat that sticks can show up as overheating, a slow warm-up or a temperature gauge that swings. Before you replace it, rule out low coolant, a leak, a water pump problem or a cooling fan that isn't running, because those can produce similar readings. Each of these engines takes one thermostat.
The 2019 Mazda CX-5 4-cylinder 2.2L, the 2011-2014 Mazda 2 4-cylinder 1.5L and the 2004-2011 Mazda RX-8 1.3L all take this thermostat, and so do many other vehicles. It is application-specific and matches OE form, fit and function. For a car not named here, run your year and engine through the "Vehicles it fits" section.
