Review: 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!)
Review: Very efficient - Easy to install, fits well and give good temperature in a Toyota Highlander.
