Myth 3: The tighter the transmission belt, the better. The water pump and generator of automobile engine are driven by triangular belt. If the belt is adjusted too tight, easy to produce tensile deformation, at the same time, the pulley and the bearing is easy to cause bending and damage. The tightness of the transmission belt should be adjusted to the middle of the belt, and the subsidence is 3% ~ 5% of the center distance of the belt pulley at both ends.
Myth: The fan belt is too tight. The summer temperature is too high, many owners think that the fan belt to tighten a little bit, can improve the cooling effect of the engine. Actually it is not correct, if improve the firmness of fan belt, fan belt too loose or too tight, will make bearing load is too large, intensify related parts of wear, and the engine's power consumption will increase, and the belt too tight will cause the belt stretching deformation, the service life of the belt will be shortened accordingly.
