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。
- 慢慢拧开冷却系统压力盖，以释放压力。
- 检查冷却系统压力盖有无异物、沉积物以及损坏。 用干净的布清洁冷却系统压力盖。 如果冷却系统压力盖损坏，更换冷却系统压力盖。
- 安装冷却系统压力盖。
- 关闭发动机室。
