Checking the technical condition
1. Turn off the ignition.
2. Disconnect the engine coolant temperature sensor connector (ECTS).
3. Remove the ECTS sensor.
4. Dip the ECTS thermistor into the engine coolant and measure the resistance between terminals 3 and 4.
5. Check that the resistance is within specification.
Withdrawal
1. Turn the ignition key to the OFF position and disconnect the negative (-) battery wire.
2. Disconnect the connector (A) coolant temperature sensor (ECTS).
3. Remove the retainer (A) and remove the sensor from the coolant temperature control unit.
Attention. Be aware that leakage may occur when the sensor is removed from the coolant temperature control unit.
4. Add coolant.
Installation
