4.11. Removal of the sensor of turning on of the electric fan on the car with the engine UEPA-331

We perform work on the cold engine.

We merge cooling liquid from a cooling system radiator (see. "Replacement of cooling liquid on the car with the engine UEPA-331"). We disconnect a wire of "weight" from the rechargeable battery.

We disconnect wires from the sensor of turning on of the electric fan.

Key "on 30" we turn out the sensor from a radiator tank opening...

... also we take out it.

Connection is condensed with a ring.

If on the new sensor the ring is absent, we rearrange it from old.

For check of the sensor we connect a tester to its contacts and we lower the sensor a carving part in a vessel with cooling liquid. We warm up a vessel, controlling temperature of short circuit and disconnection of contacts of the sensor on the thermometer (see. "Description of a design").

We install the sensor in the return sequence and we add cooling liquid to nominal level.
