1. Thermostat

Hint:

Hint

: the thermostat is numbered with the valve opening temperature.

  1. Immerse the thermostat in water and gradually heat the water.
  2.  check the valve opening temperature.

    Valve opening temperature: 80 to 84 c (176 to 183 f)

Hint

: if the valve opening temperature is not as specified, replace the thermostat.

  1. Check the valve lift.

    Valve lift: 10 mm (0.39 In.) Or more at 95 c (203 f)

Hint

: if the valve lift is not as specified, replace the thermostat.

  1.  check that the valve is fully closed when the thermostat is at low temperatures (below 77 c (171 f)).

Hint: if not closed, replace the thermostat.
