发动机停机并冷却后检查冷却液液位。

配备冷却液回收罐的发动机

    (1) 加注口盖

    (2) "冷态满(COLD FULL)"标记

    (3) "低添加(LOW ADD)"标记

  1. 观察在冷却液回收罐(如有配备)中的冷却液液位. 将冷却液回收罐中的冷却液液位保持在"满(FULL)"标记 (2) 。

  1. 慢慢拧松加注口盖 (1) ,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。 清参阅本操作和保养手册, "加注容量和建议"中关于冷却液的资料。 不要加注冷却液回收罐超过"冷态满(COLD FULL)"标记 (2) 。

  1. 清洁加注口盖 (1) 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,冷却液将会回到发动机内。

没有配备冷却液回收罐的发动机

------ 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加注管底部以下13毫米(mm) (0.5英寸(inch))之内。 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. 清洁冷却系统加注口盖,检查加注口盖垫圈的状况。 如果加注口盖垫圈损坏,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。
