冷却系统如果不进行定期检查就会引起发动机温度升高。 在进行任何测试之前应对冷却系统进行目视检查。

------ WARNING! ------

溢出的带压液体可能导致人身伤害。

如果压力表上显示有压力值,从散热器上拆卸任何软管之前,应先按压放气阀来释放压力。


  1. 检查冷却系统中的冷却液液位。 请参阅操作和保养手册 , "冷却系统冷却液液位 - 检查"。

  2. 检查冷却液的质量。 冷却液应具有下述性质:

    • 颜色应与新冷却液相似

    • 气味应与新冷却液相似

    • 没有污垢和碎屑

    如果冷却液不具备这些性质,排放并冲洗系统。 使用水、防冻液和冷却液添加剂的正确混合液重新加注冷却系统。 请参阅操作和保养手册 , "加注容量和建议 "。

  3. 查看冷却系统有无渗漏。

    注: 少量冷却液通过水泵密封渗漏出来是正常的。 这一渗漏是为这种油封提供润滑所必需的。 水泵壳体上有一个小孔,该小孔使得这些冷却液/密封润滑剂能够从水泵壳体中流出来。 少量冷却液从此小孔中断断续续地渗漏出来并不表明水泵密封失效。

  4. 确保通过散热器的气流畅通。 查看散热芯上有无弯折的散热片 还要检查散热芯之间有无碎屑。

  5. 检查风扇的驱动皮带。

  6. 检查风扇叶片是否损坏。

  7. 查看冷却系统是否有空气或燃烧气体。

  8. 检查加注口盖及其密封表面。 该表面必须清洁。
