1. If at temperature of cooling liquid 93-98 ° About the electrofan does not join, it is the most probable that the sensor of turning on of the electrofan failed. For check of the sensor it is necessary to disconnect from it wires and to close them directly, the fan should turn on even at the switched-off ignition. It means that the sensor is faulty and it is necessary to replace it.
2. Before replacement of the sensor to disconnect a wire from the "minus" plug of the accumulator. To merge cooling liquid (see subitem 1–3 subsections 4.1). To turn out the sensor (16) (see fig.

The sensor should include a lamp at 93–98 ° S.Potom let's to water cool down. At 88–93 ° With дачтик should open a chain, and the lamp will go out. If temperatures of operation of the sensor do not keep within the specified limits, it means is faulty and it is necessary to replace it.
