A bad or failing thermostat: high temperature reading and engine overheating, low temperature reading and underheated engine, temperature changing erratically, coolant leaks around thermostat housing or under the vehicle. How to fine thermostat: You can find your car's thermostat by starting at the upper radiator hose and following it to where it enters the top of the engine.

    • working great!
Wasn't hard at all to put in. I didn't drain the radiator , just removed the thermostat and put the new one in. Then I let it get up to temp by watching the antifreeze circulate . Made sure there wasn't any air trapped in the system. checked the level the next day and added (1 cup) worth of antifreeze fluid to the overflow reservoir to cap it off at full. Ez peze! ... show more

    • Not for 2015 Sonata
Review Image by Armando Lopez
This picture is what the 2015 Sonata has (from my car) and while they are similar, it does not fit the car no matter what Amazon says. We are having to buy the correct one.
