Inspecting the water motor-operated valve
Inspect the water motor-operated valve by measuring the resistance between its connectors.
1.18 Inspecting the Thermostat
Put the thermostat in a container filled with water. While heating the water with an electric
heater, measure the temperature and check when the valve begins opening and when it
becomes fully open.
∗
Because liquid packing is applied to the thermostat components before they are assembled,
do not reuse the components after disassembly. Use new thermostat components.
