REMOVAL AND INSTALLATION

INSPECTION
ENGINE COOLANT TEMPERATURE SENSOR





Raise the water temperature and measure the resistance if within the standard value.
Standard value:
2.37 ± 0.24 k Ohms [at 20°C (68°F)]
290 ± 32 Ohms [at 80°C (176°F)]

ENGINE COOLANT TEMPERATURE gauge UNIT





Immerse the gauge unit in hot water at 70°C (158°F) and measure the resistance value with an ohmmeter.
Standard value: 104 ± 13.5 Ohms [at 70°C (158°F)]
