  Q: How to service and repair a thermostat on Toyota Solara?

  A: Engine coolant drainage is the first step when servicing or repairing the thermostat. After draining engine coolant you should take off the fan and generator V belt and finally disconnect the generator assembly. Disassemble the radiator hose inlet before unconnecting the water inlet from the cylinder block once you remove its 2 nuts. Proceed to remove the thermostat. Immersion of the thermostat in water requires a slow heating process during inspection to check for valve opening temperatures between 80 to 84 degrees Celsius (176 to 183 degrees Fahrenheit). A new thermostat needs installation when the temperature range is not met. The thermostat needs replacement once the valve lift measurement is below 10 mm (0.394 inch) at 95 degrees Celsius (203 degrees Fahrenheit) or if the valve fails to close completely when the temperature drops to 40 degrees Celsius (104 degrees Fahrenheit). Put a new gasket on the thermostat first before installing it at an upward angle with the jiggle valve positioned correctly to allow 10 degrees variance. Install the water inlet by applying 9.0 Nm torque on the 2 nuts before adding the radiator hose inlet and generator assembly and fan and generator V belt. Into the system you must put engine coolant while inspecting for fluid leakage.
