Coolant Temperature Sensor

Remove coolant temperature sensor. Sensor is located near thermostat housing (2-wire connector). Place end of sensor in water, with terminal connector portion of sensor slightly above water.

Gradually heat water, and read resistance values across terminal connectors. See COOLANT TEMPERATURE SENSOR RESISTANCE table. If resistance is not within specification, replace sensor.
