WARNING: This page is about a different variant/trim than selected.
- Disconnect the negative battery cable.
- Drain the engine coolant. (See ENGINE COOLANT REPLACEMENT .)
- Disconnect the ECT sensor connector.
- Remove the ECT sensor. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION .)
- Place the ECT sensor in water with a thermometer, and heat the water gradually.
