5.6. Check, removal and installation of the electric fan of a radiator


1. Tension to the electric fan of a radiator moves via the lock of ignition, the relay and the fuse. The electric chain of the fan of a radiator is run by the thermal sensor which is installed sideways a radiator.
2. Check operability of the thermal sensor of the fan of a radiator. The fan has to turn on at excess of working temperature of the engine, that is several minutes prior to an entrance of an arrow of the index of temperature of the engine to the red sector. If the fan does not turn on, remove wires from the thermal sensor, connect them among themselves and include ignition. If the fan starts working after that probably the thermal sensor which is subject to replacement failed.
3. In case the fan still does not work, check whether tension to the thermal sensor moves. If tension on the thermal sensor is absent, perhaps, wires are damaged or the fuse fused. If tension moves to the thermal sensor, check reliability of connection it with a mass of the car.
4. If the thermal sensor and an electrical wiring in good shape, then, perhaps, is damaged the radiator fan engine. For check of the electric motor disconnect from it the electric socket and, using additional wires, give tension directly on the engine. If at the same time the electric motor does not work, so it is faulty and it needs to be replaced.


1. Remove a weight wire from the accumulator.
2. Disconnect the electric socket from the radiator fan electric motor. Release clips of a plait of wires of the electric motor of the fan of a radiator and move a plait of wires aside.
3. Unscrew fastening bolts from two parties in the top part of a casing of the fan of a radiator, then reject a fan casing to the engine, move it up and remove from a radiator.
4. Unscrew three nuts and remove the radiator fan engine from a casing. If necessary remove a spring bracket and remove a krylchatka from a radiator fan engine shaft.
5. If the radiator fan engine is faulty, it is necessary to replace it as repair of the engine is not provided.


1. Installation is made in the sequence, the return to removal. At the same time check that the lower part of a casing of the fan of a radiator correctly was established on a radiator.
2. In conclusion start the engine, warm up it up to the normal working temperature and check that the fan of a radiator works.
