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散热器盖已经冷却到可以徒手触摸时，再慢慢拆下过滤器盖以释放压力。 冷却系统调节器含碱。 应避免它与皮肤和眼睛接触。 |

| 故障诊断与排除测试步骤 | 数值 | 结果 |
1. 检查喷油器套筒或喷油器套筒密封 A. 拆下阀室盖。 B. 从缸盖上拆下喷油器。 有关详细信息，参考拆解和装配手册。 C. 对冷却系统加压以识别泄漏的喷油器套筒。 注：测试期间，请勿让冷却系统上的压力超过 详情请参阅系统操作 / 测试与调整手册。 |
泄漏 |
结果：喷油器套筒和喷油器套筒密封正常。 结果：喷油器套筒和喷油器套筒密封不正常。 修理：拆下泄漏的喷油器套筒。 仔细检查套筒是否损坏。 如果喷油器套筒上有可见的损坏迹象，更换套筒。 更换喷油器套筒的 O 形密封圈并重新安装套筒。 更换任何损坏的部件。 注：冷却液也有可能污染燃油系统。 发动机停机后，冷却系统中滞留的压力可能导致冷却液流入燃油系统。 肉眼检查燃油箱中有无冷却液。 冷却液污染燃油系统可能导致喷油器和其他燃油系统部件损坏。 确认故障已排除。 |
