## Description

Aisin OE matched engine coolant thermostats are designed for efficient, consistent performance and manufactured using only the highest quality materials. With superior OE technology and know-how, Aisin ensures that every thermostat provides perfect OE form, fit, and function and features the correct OE specified operating temperature. Gasket included. Founded in 1965 to produce original equipment automotive parts, Aisin has grown into a 25+ billion global enterprise with approximately 70,000 employees worldwide.

Review: 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!)
