3.

With water temperature at 68° F., resistance value obtained should be 2-3 kilo ohms.

4.

Heat water until temperature is approximately 122°F Resistance value obtained should be 700-1000 ohms. If resistance values obtained are not
within the specified temperature ranges, replace coolant thermosensor.
