拆卸步骤

开始:

  1. 如有必要,拆下散热器总成。

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

热的冷却液、蒸汽和碱会造成人身伤害。

在工作温度下,发动机冷却液是热的而且处在压力下。 散热器和所有到加热器的管路或发动机中都有热的冷却液或蒸汽。 与它们的任何接触都会造成严重烫伤。

只有当发动机停机且冷却系统压力盖已经冷却到可以徒手触摸时,再慢慢拆下冷却系统压力盖以释放压力。

不要试图在冷却液还热的时候去拧紧软管接头,软管会脱落而造成灼伤。

警告:冷却系统的冷却液添加剂含碱。 应避免它与皮肤和眼睛接触。



注意

保持所有零件清洁无杂质。

杂质会造成快速磨损和缩短部件寿命。



注意

在进行检验、保养、测试、调整及维修产品期间,必须小心以确保装好排放出的油液。 在打开任何舱室或解体任何储有液体的部件之前,要准备好合适的容器收集液体。

有关收集和盛接 Cat 产品上油液的适用工具和用品,请参阅专门出版物, NENG2500, "代理商维修工具目录"。

按照当地法规和要求处置所有液体。


  1. 从冷却系统将冷却液排入合适的容器以便保存或废弃这些冷却液。 请参阅操作和保养手册, "冷却系统冷却液 - 更换"。
