    Genuine Toyota part

    Would highly recommend this seller. It is a genuine Toyota Part. I compared it to my original part it was the same quality and exact fit. Before this I purchased Aisin brand "Made in Japan" thermostat on Amazon, it was a very bad quality, made of very flimsy cheap plastic material, while tightening it broke. I put this on right now with a new thermostat on my 2010 Prius, the temperature came down from mid-90s to mid 80s Celsius. 👍. Check engine light went off.
