    • Fits 2006 IS350
This part fit great and is made very well. Fixed cooking issues on a 2006 IS350

    • An OEM part. Fit my 11 GS350
It is an OEM part with "Toyota" rubbed off and replaced with a "TAMA Thermostat" sticker. They and AISIN are pretty much an OEM supplier to the major Japanese brands. Your reliable transmission? Made by AISIN. They probably sell any overstock as their brand. 100% you can trust this aftermarket brand. Toyota does, puts it in their box, charges $30 more. It is important to have original OEM for a plastic housing, some Fords have this similar setup and fail. If I had to do over replacing it, I would have removed the water housing (like the book says). But it is doable with some creativity leaving it on and removing the hoses. Spec is 7ft/lbs-84 in/lbs for the nuts (or bolts, depending how they come out!). Do not overtighten! I used a no spill funnel to fill the system, was due for 100K service. If the review stays the same, the part is working. ... show more

This is the exact company the makes all mechanical parts for these engines/transmissions. The sensors are made by Denso and AISIN makes the rest. peel the sticker back and see for yourself. If anybody had an issue is most likely they have a 2GR and did not bleed the air out the bleeder.

    • Fits and works great on 2007 IS350
Authentic OEM replacement for 2007 IS350. Works great, no leaks, and is identical to the original thermostat. Probably didn't need replace it but why not. It's extra insurance since I'm already replacing the water pump anyway.
