10.21.2. Replacement of the sensor of the index of temperature of cooling liquid

You will need a high head "on 21" (a candle key).

Good advice
Observing security measures, carry out work on replacement of the sensor on the cold engine or not to burn a hand use gloves made of cloth and clothes with a long sleeve.

1. Disconnect a wire from the minus plug of the rechargeable battery.
2. Partially merge cooling liquid from a radiator (see. "Replacement of cooling liquid").
3. For convenience of work remove the air filter (see. "Removal and installation of the air filter").
4. Squeeze a block …
5. … also disconnect it with a wire from a sensor conclusion (for descriptive reasons the sensor of temperature of the ESUD cooling liquid and a water branch pipe are removed).
6. Weaken a sensor inhaling …
7. … also turn out it from the water channel of the block of cylinders.

So the sensor of the index of temperature of cooling liquid looks. Pay attention to the marking applied on the sensor case to buy the sensor with the same parameters.

8. For check connect a tester in the ohmmeter mode to a conclusion and the case of the sensor. Sensor resistance at the room temperature has to make 1,5–1,7 kOhm.
9. For measurement of resistance on sensor conclusions at various temperature conditions lower the sensor in hot water and track change of its resistance in process of water cooling: it has to increase. If the sensor does not react to change of temperature, then it needs to be replaced.
10. Install the new sensor as it should be, the return to removal.
