Cooling equipment is indispensable and is another fan because the radiator honeycomb heat transfer between the air and the heat balance occurs. Current car radiator fan is mostly driven by the electric motor. Because they are easier to control with the drive belt. But there are limits that can not be very great because the machine has less power. At the air flow rate is due to the high temperatures of the engine as a diesel, also requires that the fan belt using power from the engine.
Radiator fan does not normally require any maintenance if it is damaged, replace it. However, you must regularly check the condition and operation periodically the state and the operation of the radiator fan. This should be done every time you check the coolant level. So, make sure that the fan blade is broken or to change. Check that the mounting points and the windscreen firmly in the correct position and with no signs of wear. Power cord and plug that in its absence is not broken or frayed and check the radiator fan control circuit. With crank the engine and observe the normal fan. While the new radiator fan motor does not work. Fan starts to rotate when the engine temperature is higher than the normal temperature (about 85-90 degrees Celsius) and stop when the temperature of the engine lower than these levels. Switching back and forth like this forever.
So, if this. Radiator fan in operation all the time. Shows that there is something wrong. This may be cooling. Or the control of the fan. Use water spray boiler. (Do not spray directly on the engine because it would cause a short circuit. OR damage to internal components), then injecting the fan stops operating, it is shown that the thermal efficiency of the boiler, such as the amount of refrigerant is not sufficient. Clog the cream cooling. The iron rust in the radiator or components of the cooling system. (Water pump, thermostat Stoughton) deficiency and water, but to ensure that the temperature of the engine, and then reduced to a lower temperature. Fan is not running, the fan control. (Thermo-switch) deficiency.
Finally a defective fan does not turn, check the fuse first. (Location of fuses for each type of user templates) that is next to the power cord and the plug polarized. If there is nothing wrong with that. If a fan or a control circuit defective. To the solution in this case, would have to leave the mechanic to have the best experience. Not to solve the problem. Although it is not worth it. During the control circuit of the fan is connected to the computer models. Operation of the motor. Bad luck to make a box that will become a big problem.
