Beck/Arnley Engine Coolant Thermostat P/N:143-0804
Beck/Arnley 143-0973 thermostat for the 2011-2012 Hyundai Sonata 2.4L and other vehicles opens and closes with coolant temperature to hold the engine at its operating temperature.
An engine that runs hotter than normal, warms up slowly or shows a wandering temperature gauge can mean the thermostat is stuck. Low coolant or a leak can show up the same way, so with the engine cool, look at the coolant level and the area around the housing before you replace anything.
Listed for a wide range of Hyundai and Kia models, it also fits the 2011-2015 Kia Optima 2.0L / 2.4L and the 2014-2016 Kia Sportage 2.0L, with one thermostat per vehicle. If your car is not named here, look it up in the "Vehicles it fits" section.
