How to install the thermostat on 2009 Toyota 4Runner?

Users need to lay a new gasket on the water inlet which houses the thermostat before tightening the three nuts to 9.0 Nm (92 kgf-cm, 80 in-lbf). As a next step secure the radiator outlet using the No.2 hose clamp or clip. Engine coolant should be added before checking for leakages. Screw on the V-bank cover with its corresponding 2 nuts then use a torque wrench set to 7.5 Nm (76 kgf-cm, 66 in-lbf).
