Coolant Thermosensor

1. Place coolant thermosensor into a container of water.
2. Install a suitable ohmmeter onto coolant thermosensor and measure resistance of coolant thermosensor.
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.
