配备冷却液回收罐的发动机

发动机停机并冷却后检查冷却液液位。

  1. 观察冷却液回收罐(如有配备)中的冷却液液位。 将冷却液回缩罐中的冷却液液位保持在"满(FULL)"标记处。

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

    加压的系统: 热的冷却液能造成严重的烫伤。 在发动机停机,等待冷却系统部件冷却下来后再打开冷却系统加注口盖。 缓慢松开冷却系统加注口盖,以释放掉所有压力。


  1. 慢慢拧松加注口盖,以释放掉所有压力。 取下加注口盖。

  1. 将正确的冷却液混合液加注到罐中。 有关冷却液正确混合及类型的信息,请参见专门出版物, SEBU6251, "卡特彼勒市售柴油发动机用液建议" 。 有关冷却系统容量的资料,请参阅操作和保养手册, "加注容量和建议"。 不要加注冷却液回缩箱超过"冷态满(COLD FULL)"标记。

  1. 清洁加注口盖和罐口。 将加注口盖装回去,检查冷却系统有无渗漏。

注: 发动机正常操作期间,随着冷却液温度升高,冷却液将会膨胀。 发动机运转期间,多余的冷却液将会被压入冷却液回收罐中。 当发动机停机并冷却时,回收罐中的冷却液将会回到发动机内。

不配备冷却液回收罐的发动机

发动机停机并冷却后检查冷却液液位。

冷却系统加注口盖

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

加压的系统: 热的冷却液能造成严重的烫伤。 在发动机停机,等待冷却系统部件冷却下来后再打开冷却系统加注口盖。 缓慢松开冷却系统加注口盖,以释放掉所有压力。


  1. 慢慢拆下冷却系统加注口盖,以释放掉压力。

  1. 将冷却液液位保持在距加注管底部的距离在13mm (0.5 英寸)以内。 如果发动机配备了观察孔,保持冷却液液位在观察孔内适当的水平。

    典型加注口盖垫圈

  1. 清洁空气系统加注口盖,检查加注口盖垫圈的状况。 如果加注口盖垫圈损害,更换冷却系统加注口盖。 重新安装冷却系统加注口盖。

  1. 检查冷却系统是否渗漏。
