Warning. When removing and installing the coolant temperature sensor, do not touch the tool to its connector (plastic part).
1. Drain the coolant, disconnect the connector from the coolant temperature sensor and unscrew it (pic. 6.25).
Pic. 6.25. Location of coolant temperature sensor
2. Heating the sensor in a vessel with water, measure the resistance between the contacts of the sensor connector (pic. 6.26).
Pic. 6.26 Measuring the resistance of the coolant temperature sensor
Rated resistance, kOhm:
- at a temperature of 20°C: 2.1-2.7
- at a temperature of 80°C: 0.26-0.36
3. If resistance differs from demanded replace the gauge of temperature of a cooling liquid.
4. Apply a thin coat of sealant to the sensor threads (pic. 6.27).
Pic. 6.27. The place where the sealant is applied to the threads of the coolant temperature sensor
Recommended sealant: 3M NUT Locking Part 4171
5. Screw in the sensor and tighten it to 29 Nm.
