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.
Unit: ℃ (°Ｆ)
Valve opening
temperature
8 mm (0.315 in.)
valve-lift temperature
82±1.5 (179.6±2.7)
95 (203)
This is a “hot” operation. Pay every attention to
prevent burns and fire.
