Dip the sensor element in hot water and measure the resistance.
Rated value:
- 2.1-2.7 kOhm (at 20°C);
- 0.26-0.36 kOhm (at 80°C).
If the resistance value is out of specification, replace the sensor.
Apply sealant to the sensor threads.
After installing the coolant temperature sensor in place, tighten it and connect the connector to the sensor.
