To get the most out of any car’s engine, increase its resource and reduce fuel consumption, the temperature of the coolant must be stable. Even small, only a few degrees, deviations from the optimum lead to a change in the gaps between the mating parts, the occurrence of stresses, deformation in them, a decrease in efficiency and efficiency.

At first glance, these changes are not so significant, and you can put up with them. But, they say, water sharpens a stone. Temperature fluctuations, in addition to increasing fuel consumption, reduce the durability of the motor. To “curb” the temperature, a thermostat and an electric fan are built into the cooling system. The first, as far as possible, opens and closes the passage of "water" into the radiator, but is rather inertial. The second - at the catch, guards overheating and is included in the work a few degrees before boiling. But if modern foreign cars both of these devices work quite clearly and the arrow on the temperature gauge almost does not move, then the Volga is not so strict. On the highway, the arrow barely exceeds 90 °, and in a traffic jam looms near the red zone - you see, it will boil!
The easiest way to protect the motor from overheating is to display the forced fan button on the panel. But today a more convenient and accurate version of temperature stabilization has appeared - an automatic microprocessor unit "Silych". He is able to solve several problems at once: turn on the fan as necessary and adjust its speed; ensure full inclusion at a lower temperature and thus give the engine some temperature head start; finally unload the sensor contacts. The device is produced in a separate unit or built-in to a fan motor, and it can work with any sensors (parameters can be configured during installation).
