1.2 Inspecting the thermostat
Place the thermostat in a container filled with
water. While heating the water, measure the
water temperature at which the thermostat starts
to open, and also the water temperature at which
the valve lift reaches 8 mm (0.315 in.). If the
measured temperatures do not conform to the
standard values, replace the thermostat.
