------ 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。


  1. 将冷却系统中的冷却液抽到缸盖以下液位。 请参阅操作和保养手册, "冷却系统冷却液 - 更换"。


    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。
