How to service and repair the thermostat on Toyota 4Runner?

Service and repairs of the thermostat start with drained engine coolant followed by V-bank cover uninstallation. Release the No.2 hose clamp or clip on the radiator outlet before erasing the water inlet and thermostat and gasket by removing the 3 nuts. Begin by checking the magnitude of water valve opening temperature on the thermostat before dipping it into water and heating the water slowly as you confirm the valve opening temperature falls between 80 to 84 degrees Celsius (176 to 183 degrees Fahrenheit). Replacement of the thermostat must be done when the valve opening temperature does not match the specified range of 80 to 84 degrees Celsius (176 to 183 degrees Fahrenheit). The valve lift needs inspection while the water reaches 95 degrees Celsius (203 degrees Fahrenheit) because any measurement under 8.0mm (0.31 in.) requires a thermostat replacement. A fully sealed valve must exist prior to a thermostat reading below 40 degrees Celsius (104 degrees Fahrenheit). Replacement of the thermostat becomes necessary if the valve remains open. New gasket installation begins with placing it on the water inlet that includes the thermostat then tightening the 3 nuts to 9.0 Nm (92 kgf/cm, 80 in. lbs.). First reconnect the radiator outlet using the No.2 hose clamp or clip while adding engine coolant before checking for leaks. Use the provided 2 nuts to reinstall the V-bank cover and torques them to 7.5 Nm (76 kgf/cm, 66 in. lbs.).

How to install the thermostat on Toyota Tacoma?

The 2TR-FE cooling system thermostat requires installation by placing a new gasket first then positioning the jiggle valve upward while maintaining alignment within 10 degrees of the designated location. Begin by placing the new gasket onto the thermostat before positioning the jiggle valve upwards within a ten-degree range. Afterward, install the water inlet together with a new gasket using bolt and nuts and secure them with 20 Nm (204 kgf-cm, 15 ft-lbf) torque. Soon after installation you should add engine coolant then verify for any fluid escape.
