Attention! Wait until the engine has completely cooled down before starting this procedure.
Models with a four-cylinder engine
Warning. Handle the ECT sensor with care. Damage to the ECT sensor has a negative effect on the operation of the entire fuel injection system.
Note. The ECT sensor is located at the left end of the cylinder head.
1. Disconnect the ground wire from the battery (see paragraph 1 of chapter 5). Partially drain the coolant from the cooling system (see chapter 1).
2. Disconnect the ECT sensor electrical connector (pic. 6.2).
Pic. 6.2. To remove the ECT sensor (A) from the left end of the cylinder head on a four-cylinder engine, disconnect the electrical connector (IN) and unscrew the sensor from the cylinder head
3. Turn out the gauge from a head of cylinders.
4. Seal the sensor threads with Teflon tape (pic. 6.4).
Pic. 6.4. Wrap ECT sensor threads with Teflon tape to prevent leakage
5. Installation is carried out in the reverse order of removal. Tighten the sensor securely. Recharge the cooling system (see chapter 1).
Models with V6 engine
Warning. Handle the ECT sensor with care Damage to the ECT sensor will adversely affect the operation of the entire fuel injection system.
Note. The ECT sensor is located on the right side of the engine (where is the timing belt located), on the coolant distribution housings.
6. Disconnect the ground wire from the battery (see paragraph 1 of chapter 5). Partially drain the coolant from the cooling system (see chapter 1).
7. Disconnect the ECT sensor electrical connector (pic. 6.7).
Pic. 6.7 To remove the ECT sensor from the coolant distribution housing on a V6 engine, disconnect the electrical connector (1), and then check the sensor (2)
8. Remove the sensor from the coolant distribution housing.
9. Seal the sensor threads with Teflon tape (pic. 6.4).
10. Installation is carried out in the reverse order of removal. Tighten the sensor securely. Recharge the cooling system (see chapter 1).
