1C-8 Engine Electrical Devices: For Petrol Engine Model
Engine Coolant Temperature (ECT) Sensor
Removal and Installation
Removal
1) Disconnect negative cable at battery.
2) Drain coolant referring to "Cooling System Draining:
For Petrol Engine Model in Section 1F".
WARNING
!
To avoid danger of being burned, do not
