冷却液,又被称之为防冻液,是车辆散热系统中必不可少的一环。北方的朋友可能会有些感同身受,寒冷的早晨启动车辆时,仪表盘会提示液位报警,而在热车后报警又会悄然解除,难倒冷却液也会穿越?

冷却液液位为什么会时高时低?

冬季冷却液液位偏低是冷却液热胀冷缩造成的,如果外界气温足够低的话会缩减的更厉害,直至低于标准液位下线,仪表报警。冷却液热胀冷缩是很常见的现象,几乎所有的汽车沙吧体育平台都会出现,只不过因为有液位刻度作为标准,所以能很直观的查看到。另外,冷却液不是100%的充满整个冷却系统循环管路中,管路中总会存在少量空气,空气的膨胀系数远高于冷却液,所以冷却液液面随温度变化时高时低是正常现象。如果未出现冷却液大量缺失,只需少量补充即可。

冷却系统正常工作是保障发动机正常运转必不可少的条件,任何有关冷却液系统的故障都不能小视。冷却液缺失必须及时补加,长时间缺失冷却液会导致冷却系统散热不良,发动机高温过高,严重情况下可使缸盖变形、活塞拉缸、发动机报废。目前很多车型仍然使用指针式水温表,驾驶员一旦发现水温表指针高于正常刻度,不能拖延,必须立即维修。(文/汽车之家 杜雷)
