How to service the thermostat on Scion tC?

Quieting down the engine coolant is the initial step to perform thermostat maintenance. The first action involves water inlet removal through unfastening two nuts before disconnecting the cylinder block. After the coolant evacuation step, proceed to remove the thermostat. The installation process begins with a new gasket applied to the thermostat followed by placing it in position with the jiggle valve oriented upward throughout a 10 degrees range near its recommended spot. For water inlet repair install the 2 nuts while tightening them to 9.0 Nm (92 kgf-cm, 80 inch lbs.). The last step includes engine coolant addition while inspecting for leakage.
