Coolant Temperature Sensor

Coolant temperature sensor is located in cylinder head coolant outlet next to thermo-time switch. Remove connector from sensor and measure resistance across terminals. Resistance value depends upon coolant temperature. See COOLANT TEMPERATURE SENSOR RESISTANCE table. If values are not as specified, replace sensor.
