防冻液是一种高效能冷却介质,与水相比它具有凝固点低、沸点高,在使用中能防腐、防锈、防水垢生成,延长发动机使用寿命,并可减少驾驶员加水放水的劳动强度,因此,大力推广使用防冻液是行之有效手段之一。然而,有许多驾驶员不了解使用方法,造成了不必要的浪费,并引起发动机故障。近期我部保养了一台桑塔纳轿车,发现车辆运行中,发动机温度总是超出正常温度20℃以上(使用防冻液的汽车发动机温度高于正常温度10℃左右属于正常范围),经检查发现,水箱
Antifreeze is a high-performance cooling medium, compared with water, it has a low freezing point, high boiling point, can be used in corrosion, rust, scale generation, to extend the life of the engine, and reduce the labor intensity of the driver to add water Therefore, to promote the use of antifreeze is one of the effective measures. However, many drivers do not understand how to use them, causing unnecessary waste and causing engine malfunctions. Recently, I maintained a Santana sedan and found that when the vehicle is running, the engine temperature is always above the normal temperature of 20 ℃ (using antifreeze vehicle engine temperature higher than the normal temperature of about 10 ℃ belongs to the normal range), the inspection found that the water tank
