Review on 90916 A3003 Coolant Thermostat Highlander 1994 2018 by Zha Rivera

This thermostat replace the old one for Toyota Matrix 03. Pulled out. After scraping off the old gasket I used a cotton swab with ultra black permatex and placed it around the edge where the thermostat goes and it fitted perfectly. Everywhere I looked online I found that the gaskets were sold separately and were in fact a necessary part of a thermostat replacement. I liked that a gasket was included in the box but I wasn't expecting this to be a really high quality part so it was a good buy for me. So the only tools needed to replace the thermostat are this thermostat and Permatex after the hose is removed. connected to the cooler.
