Thanks for the great informative video. I am replacing Temperature Sensor in Corolla 2009 just for preventative maintenance. The new sensor is coming with coper gasket. Could you advise if any sealant (like Permatex anti seize) should be applied to the Sensor's thread. I will appreciate your advice.
