Complete your water pump or radiator replacement job with this! Fitment is spot on and so far after 3k miles not one issue! 2008 Toyota Tundra 5.7 4wd.

Well, this one took my breath away. Most people look @ the quality of their purchase. Aisin did not dissappoint. Wow, truly impressed the minute I opened up the box. This is very solidly built. I've replaced several of these throughout the years on different vehicles and they usually feel cheap and flimsy like they're not going to last you. Not this one, the plastic housing is solid and the thermostat and o-rings feel nice and sturdy as well. It has some weight to it, not too excessive though. Perfect fit on my 2010 tundra. This one is a keeper. Thanks Aisin for producing quality products. Definitely worth the cost and recommend.

Perfect replacement for my oem Lexus thermostat

Same manufacturer as OEM and a perfect fit and performance. My factory one is still working just fine but I'm going to replace it with the water pump. Like how the housing is painted from the factory. Another critical engine protection part that is not worth going cheap.

It fits prefect on 2008 toyota tundra haven't had any issues with it its open up at the right temperature no leakage easy installation quality made

OEM quality.

I would like to recommend this to anyone with a 2018 Tundra 5.7. Bottom nuit is hard to remove unless you remove the wiring harness next to it. Then all is good.

Great, same as OEM part from Toyota

Looks good and is maintaining the same temp the original did. The old one was working, so this was preventative as I was changing the water pump, hoses and rad anyway.

Hope it lasts 17 years like my original one did.

Identical to factory
