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.

Worked as advertised. This is a genuine OE replacement for a lot of Toyota's including the one we worked on. Replacement went in fine, no issues.The only caveat is that this does not come with the O-ring/gasket so ensure that you order its separately or have one available on hand

This is exactly what I needed for way less than the local shop wanted for it.

Long story short. My Tacoma from new would pretty much run at 184-186. At a point in its life I did a regular maintenance job to the cooling system and the thermostat was one of the many new parts bought from a Toyota stealership. From that point on, my coolant temp would fluctuate from 188-193 and climb all the way up to 210 in in high heat hwy driving. Since then I’ve been through 2 more Toyota thermostats, fan clutch and even a radiator. No change.Did some reading/research and someone in a forum mentioned the gen 1 tacomas came from the factory with Aisin thermostats. I decided to test this theory. As you can see in the photo attached to this review, there’s definitely a physical difference. After install, the truck is back to normal operating temp.:).I haven’t tested it hard yet, but I’m pretty confident this was the issue. FYI all temps were read with Scan gauge plug in to my obd2 port.I hope this info helps many other save lots of time, money and frustration.Garrett ;)
