Check cooling system检查冷却系统

Inspection procedures检查程序

1. Check the coolant level1. 检查冷却液液位

1 Check the coolant level in the temperature control system.检查温控系统冷却液液位。   Note:提示： ♦  The coolant level of the temperature control system should be between the "MAX" and "MIN" marks.温控系统冷却液高度应位于“MAX”与“MIN”标记之间。

2. Check the freezing point of the coolant2. 检查冷却液冰点

1 Use a pipette to drop the cooling liquid on the refractometer glass and observe the freezing point value of the cooling liquid.使用吸管将冷却液滴在折射计玻璃上，观测冷却液冰点数值。   Caution:注意： ♦  When the cooling system is at high temperature, do not open the expansion tank filling cap, otherwise high-temperature steam or boiling coolant will splash out from the expansion tank and cause harm to the human body.当冷却系统处于高温状态时，请勿打开膨胀箱加注盖，否则高温蒸气或沸腾的冷却液会从膨胀箱中飞溅出来对人体造成伤害。 ♦  The coolant is toxic. Please keep the container sealed and store it out of the reach of children. If you find it has been accidentally ingested, seek medical attention immediately.冷却液有毒，请保持容器密封并存放在儿童不易触摸到的位置，如果发现误食，立即就医。 ♦  Prevent coolant from coming into contact with skin or eyes. If this occurs, rinse immediately with plenty of water.防止冷却液与皮肤或眼睛接触。如果发生，请立即用大量清水冲洗。 ♦  Never add preservatives to coolant as this may damage components.切勿向冷却液中添加防腐剂，否则可能损坏部件。 ♦  Do not mix it with other coolants. The freezing point of the coolant selected for the vehicle should be 10-15°C lower than the local minimum temperature.切勿与其他冷却液混用，车辆所选择冷却液冰点应低于当地最低气温10-15℃。 ♦  The corrosive nature of coolant can damage the paint surface. If coolant spills when filling, immediately use an absorbent cloth to absorb the excess coolant and clean it with vehicle cleaning agent.冷却液的腐蚀性会损坏漆面。如果冷却液加注时外溢，立刻使用吸水布吸收掉多余冷却液并使用车辆清洗剂进行清洗。

2 Read the coolant freezing point value.读取冷却液冰点数值。 Coolant freezing point: -35℃冷却液冰点：-35℃

3. Check the cooling system pipes3. 检查冷却系统管路 1 Check whether the cooling system connections are tight and check the radiator and pipes for cracks or leaks.检查冷却系统的各个连接口是否紧固，并检查散热器和管道是否有裂缝或泄漏。 2 Check whether the radiator fins are blocked, deformed or corroded, and clean or replace them if any.检查散热器翅片应堵塞、变形、腐蚀，如有进行清洁或更换。 3 With the vehicle started, check the electric water pump for leaks and abnormal noises.在车辆启动的情况下，检查电动水泵是否有泄漏，以及是否存在异响。 4 Use a diagnostic instrument to read the vehicle data stream to ensure that the operating temperature of the high-voltage battery, integrated power supply, drive motor and other components is normal.使用诊断仪读取车辆数据流，确保动力电池、集成电源、驱动电机等部件工作温度正常。
