When the engine is hot, the cooling fan can be activated at any time - be extremely careful!
Examination
The electric fan is powered by a battery. Fan circuit includes safety fuse, ignition switch and relay (see chapter Onboard electrical equipment). The operation of the fan is controlled by an electronic control unit based on data from the coolant temperature sensor.
To check for proper operation of the fan, start the engine and warm it up at idle to normal operating temperature. The fan should work before the arrow of the engine temperature gauge on the car's instrument panel approaches the overheating sector on the dial. If the fan does not turn on, check the power supply on the corresponding wire of the fan and relay (see chapter Onboard electrical equipment). A power failure can result from a blown fuse, failed ignition switch, failed relay, or damaged wiring. It is also possible that the fan drive motor may fail.
Removing
1. Disconnect the negative cable from the battery.
2. On naturally aspirated diesel engine remove the air intake sleeve.
3. On turbodiesel remove the dipstick guide tube from the cylinder head.
4. With the appropriate configuration, remove the power steering fluid reservoir, and take it aside along with the hoses.
5. Separate a multicontact socket of the e/motor of the fan.
6. Turn out bolts of fastening of a cover of the fan with the e/motor, extend from the left arm and take out it together with the e/motor upwards.

On the diesel engine, the brackets are on the left and right.
7. Remove the clip from the e/motor shaft with a screwdriver and remove the impeller.

Installation
1. Installation is in the reverse order to the removal of the components. Tighten fasteners to the required torque. When installing the impeller, make sure that the pin on the e/motor shaft fits into the groove of the impeller.

2. Start the engine and let it warm up until the fan motor turns on.
