Review on TOYOTA 90916 A3003 Genuine Toyota Thermostat by Timothy Johnson

Replaces thermostat on Camry SE 4-cyl. 2012 (AR2FE engine) with 130,000 miles. At the same time, hoses, belts and coolant were changed (a first for this car). Unfortunately, and frankly unforgivably, a thermostat gasket is NOT included (just cheating Toyota consumers). Luckily in my case the old gasket was still in good condition to be reused (I also applied AT-205 to the gasket to hopefully extend the life of the rubber gasket). The old thermostat showed signs of rust and aging. So I'm glad he was replaced. On this engine, be sure to align the rocker arm to the 12 o'clock position. However, it is always a good idea to check the orientation of the rocker valve before removing it. I hope that the new thermostat will last another 130,000 km.
