As Good as the Original
This thermostat functions just as well as the original from Toyota. Since Aisin is an OEM supplier, this may be the exact same part. It fits perfectly in the 1MZ-FE engine in my 1999 Camry. Doesn't come with the gasket, but the gasket is cheap and readily available. Just make sure the "jiggle" valve is on top when your install it.

A Great alternative to oem
"What such high quality at an affordable price! It's the same quality as OEM, but at a lower price. Please do not buy the cheap, unbranded ones just to save a few dollars; think about the long term instead. Paying only 10-15 dollars for a high-quality one is far better than buying a cheap one that won't last long. The only con I noticed is the exclusion of the gasket; you need to buy it separately."

High Quality Thermostat
Tested sat out of the box for once, I've tried a lot of thermostat brands (even Napa) and they are very hit or miss these days. Quality control since the pandemic has been atrociously worse. Aisin however has remained top notch. Opens right at the advertised temp and opens linearly until maximum opening, and reliably opens and closes effectively. Works well. Don't forget a thermostat gasket if you need one (but don't add one if you don't!)

Good to go!
After a snafu with the original order, a replacement was promptly sent to me. The thermostat is what the OEM uses, so I expect many, many years of service out of this.

Aisin or nothing
Delivered on time and is to OE standard for those of you who don’t know, Aisin, is the OE manufacturer for Toyota when it comes to water pumps and thermostats. Great quality. Gasket needs to be purchased separately. I would recommend Aisin above Gates, etc when it comes to this particular part. Also, if you’re changing the water pump you might as well change the thermostat as well so you don’t have to refill the coolant twice.
