Genuine Toyota 90916-03075 Thermostat

Very good!fits and works

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.

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".

Its been a week works great so far

Order/delivery seamless and on-time. What's not to like? Recommend. Perfect fit.

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.

Item does as described with no issues. It is a genuine part, it came in the red Toyota box.Just remember that it does not come with the gasket. The Fel-Pro 35445 Gasket is the one that fits.

Worked better than aftermarket parts and a perfect fit with a good price.
