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

  • Check the fit
It doesn't fit into the water pump housing, without leaking.

  • Seems to be working on my 2016 Kia Optima Lx.... car temp fine.
Replaced my 2016 Kia Opt LX water thermostat. This item does fit and the temp is exact for my car. The stock OEM thermostat has a indent marker for placing into the car.... this generic replacement does not, so when you pull it, you want to position it the same way as you took the old one out. The other thing is the stock OEM is longer than this replacement.... but seems to work fine. After purging the air out of the system and replacing the fluids with new... temp is perfect so far. In fact, with my new thermostat and fluids, my temp is a fraction lower and my fans do not turn on so much... runs much cooler. ... show more

I got what I paid for. Best to get a not-so-cheap brand. Lesson learned.

  • Missing part
I bought this thermostat for my Kia Optima. It was supposed to have a rubber gasket around it. When I got the part, it did not have the rubber gasket as pictured above.
