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".

There are some things you just don’t go off-brand. I’m not messing about with the coolant system. Replaced the radiator, hoses, fluid, and cap for 2001 4 Runner back in 2018. Still going strong Everything was genuine Toyota but the fluid. I’ll take made in Japan over made in China 24x7x365.

5.0 out of 5 stars Beware of imitations!

This is the only thermostat for the Toyota 3.4L engine that works!

Having battled an over heating problem for almost a year after I had my timing belt replaced, new water pump and thermostat (2 of them) installed by a local shop, I finally did some redneck trouble shooting and removed the thermostat completely, and that solved the over heating problem.
Ordered an OEM thermostat, and as soon as I opened the box I saw a huge difference (the link to upload photos doesn't work). The bimetal spring on the OEM thermostat is about twice that of the one on the generic one.

Further research let to more understanding of the issue. The OEM thermostat is described as a high flow thermostat, whereas most others are not.

Well worth the money!

If I can upload a photo I will do so later.

Always use a Toyota oem thermostat. They are built heavier than the non oem and usually have no failures. The 4 stars is for no gasket! $23 and you can't put a .50 gasket in the box? Come on! (That's my only gripe)

This is a genuine Toyota Thermostat! Not an aftermarket piece of junk.

If you are doing a timing job, this is a MUST to replace while you have everything open.
To avoid having to go back into the engine next month, replace the following...

- T-belt
- tension pulley
- idler bearing
- water pump
- ALL GASKETS
- Thermostat

Toss this bad boy in and enjoy your peace of mind

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