Engine cooling is absolutely necessary to maintain performance. As far as possible the engine is maintained at a temperature ideal for permanent employment to work at optimum point.
The temperature has not reached the ideal machine to make wasteful, or too high of a maximum limit can be dangerous for kitchen runway.
Along the development of engine technology, the cooling system was always an improvement. For example, an electric fan that is usually used in front engine, now used also for the car rear wheel.
As examples of the Suzuki APV or Daihatsu Gran Max and Luxio, as well as the Toyota Avanza.
In the car pull forward, electric fan because the fan is not absolutely necessary can be driven mechanically by a machine which is positioned crosswise. Well, in fact profit electric fan can also be applied to the rear traction engine.
Because more engine-driven fan draining the engine because there is a direct mechanical linkage. While the electric fan just need more current than the alternator is much less burdensome machinery.
Unfortunately, compared to other benefits, electric fans have aged faster than the mechanical fan, even though wearing the viscous system. "Generally, the age of about 3 years old electric fan," said A. Rohim, Cool air conditioner repair shop owner in the Post Pengumpen, West Jakarta.
Consider some signs that could be a clue fan dead. Examples of the Suzuki APV (Fig.1), "Usually the noise issue," he described. Try off the socket, if the noise is lost then the sound is coming from the fan motor.
But, not all cars show the same symptoms. "Like the Toyota Avanza, the fan could die instantly," continued the man is 36 years. The most obvious, immediate visible engine temperature rises up to maximum. If it is so, must replace the fan motor either APV or Avanza approximately USD 375 thousand (Fig.2).
One way that could minimize the risk of overheating the engine is to install an extra fan (Fig.3). "We usually set up for electric fan turn on when the AC live," added Rohim while calling rates following extra fan mounting USD 375 thousand.
Installation performed in front of the AC condenser (Fig.4). Most felt the effects, a gust of air conditioning will be more cold. However, if the original fan died, extra cooling fan will still help when AC is turned on. Symptoms of the original electric fan death was still detected because the engine temperature will rise if the AC off.
