Genuine Toyota 90916-03075 Thermostat by Toyota

OEM Thermostat fit perfectly for 5VZ-FE, V6 engine. Does not come with gasket though. The Toyota gasket part# is: 16325-62010. You can also use a Fel-Pro gasket 35445. Installed with the jiggle valve at the 6 o clock position per FSM manual. Purchased to alleviate a P0128 code. (also changed the engine coolant temp sensor 89422-35010) Engine temperature is now controlled between 192F and 194F.

Product is as advertised, hard to beat OEM quality. The seller took over two weeks to ship and another two weeks to arrive.

Just in time for my timing belt job. Worked great and my temp has been no higher that 192. Don’t forget to face the jiggle valve at 6 o clock.

Very good!fits and works

I have worked in parts sales my entire career, and these guys are professional. The thermostat is a genuine toyota part and very nicely manufactured. You can clearly tell the difference between aftermarket and oem as the aftmkt ones are chinsy little pieces and these oem ones are are pretty heafty for a thermostat. So overall quality is very good, and Modern Toyota is awesome to work with they got my part shipped to me 3 days earlier than their "earliest estimated delivery date".
