Nissan Juke Service and Repair Manual : Thermostat

Inspection

Place a thread so that it is caught in the valves of the thermostat.

Immerse fully in a container filled with water. Heat while stirring.

(The example in the figure shows the thermostat.) The valve opening temperature is the temperature at which the valve opens and falls from the thread.

Continue heating. Check the full-open lift amount.

After checking the full-open lift amount, lower the water temperature and check the valve closing temperature.

If the measured value is out of the standard value or unusual valve seating condition is found, replace water inlet and thermostat assembly.
