大、中、小型汽车,现已遍布农村,在寒冷的冬季,这些汽车的冷却水应怎样正确使用呢?1.注意水温对发动机的影响。冬季气温低,车体温度也低,要控制好冷却水的温度,就要用好各种保温设备,使发动机保持正常温度。发动机冷却水的温度要求在75～90℃范围内。水温过高,机体强度要受影响,机油粘度降低还会影响到润滑性能,吸气不足,马力下降,甚至导致运动件卡死。水温过低,不仅耗油 Large, medium and small cars, are now all over the countryside, in the cold winter, these cars should be how to use the cooling water correctly? 1. Attention to water temperature on the engine. Low winter temperatures, body temperature is low, to control the temperature of cooling water, it is necessary to make use of a variety of insulation equipment, so that the engine to maintain normal temperature. Engine cooling water temperature requirements in the 75 ~ 90 ℃ range. Water temperature is too high, body strength to be affected, the oil viscosity will also affect the lubrication of reduced performance, lack of inspiration, horsepower decline, and even cause movement stuck. Water temperature is too low, not only fuel
