OEM and no tricks. Perfect fit.
This is very much the high quality OEM Toyota/Lexus part and my pic shows my OEM original vs the new part. This DOES NOT include the gasket and it will need to be bought separately. The gasket is part number 16346-50010 and works perfectly in my 1998 Lexus GS400 with the 1UZ-FE.

When it comes to quality engineering and perfect fit, go with OEM. Not worth skimping out on something so important to your engine cooling system.

Be sure to order a new o-ring. as it is not provided with the thermostat.

Remember antifreeze is poisonous to Dogs/Cats/Humans. Catch as much as you can and recycle it.

Replaced radiator on my 2006 Lexus GX470 and figured while I was there, might as well replace the thermostat as preventative maintenance. No issues and seems to be working.

I feel confident that this genuine Toyota thermostat will not fail like some after market products do. I installed it in a 2002 Toyota Tundra after a radiator replacement. It fit perfectly and was easy to install except for the bottom nut on the thermostat housing which is rather difficult to access.

Exact fit as needed. Part was in perfect working condition and appearance. Seemed to be a Remanufactured part. Works great tho! Not an issue yet with this item! (Remanufactured mean part was slightly modified during assembly process) it does not mean it is used or has been used in any way. Do your research people. Know the difference between Remanufactured and Refurbished.

5.0 out of 5 stars Seems to be a genuine OEM replacement
Reviewed in the United States on February 2, 2024

Make sure you buy the proper rubber/silicon gasket. This is the thermostat only, so you'll need to buy the gasket.

The original (to the car) OEM had the specs etched into the thermostat. This had them printed on...which seems odd. In any event, it appears to be OEM, and fits/works like it should.
