Coolant Level Switch - Inspect/Test
当冷却液液位低时，低冷却液液位开关触发警报或停车。 低冷却液液位能造成发动机过热。 过热将造成发动机损坏。
如果冷却液液位低，必须向膨胀箱或热交换器补充冷却液。

为了正确操作开关，必须清洁管路和开关。
- 排放冷却液使液位低于较低的线 (2) 。 排放冷却液到一个清洁的容器以使该冷却液能被重复使用。
- 拆下开关 (1) 。 检查进出口的开口有无堵塞。 如果开口被堵塞，清理该开关。
- 检查管路 (2) 是否有堵塞。 必要时清洁管路。 压缩空气或可弯曲的金属线可用于清理管路。
- 安装开关 (1) 。
- 灌冷却液到冷却系统。 确认低冷却液液面开关工作正常。 一个工作正常的开关将触发警报直到冷却液被加到充足的量。
