1、轿车不需要加水。
2、通常所说的加水是指加防冻液。汽车上使用的发动机是水冷发动机,水冷发动机依靠防冻液在发动机内循环散热。如果没有防冻液,发动机就会出现温度过高的情况,情况严重会损伤车辆性能。
3、汽车防冻液的作用如下:保护冷却系统部件不受腐蚀;防止水垢,降低散热器散热效果;请确保引擎在正常温度范围内工作。

1, the car does not need to add water.
2, what say normally adding water is to point to add antifreeze. The motor that uses on the car is water-cooling engine, antifreeze of water-cooling engine support comes loose circularly inside engine hot. If do not have antifreeze, engine passes high case with respect to meeting occurrence temperature, the condition can mar vehicle performance badly.
3, the action of car antifreeze is as follows: Component of protective refrigeration system does not suffer corrode; Prevent furring, reduce radiator to come loose hot effect; Ensure engine works inside normal temperature limits please.
