3. Drain the coolant from the temperature control system3. 排放温控系统冷却液 1 Remove the coolant filler cap of the temperature control system.拆卸温控系统冷却液加注口盖。

2 Disconnect the battery outlet pipe assembly A, battery inlet pipe assembly B and the battery pack assembly, and drain the coolant in the battery pack assembly and pipelines.断开电池出水管总成A、电池进水管总成B与电池组箱总成的连接，排放电池组箱总成与管路内的冷却液。

3 Disconnect the water pipe IIA from IDU to ITS and the front drive motor, and drain the coolant in the front integrated electric drive motor.断开IDU至ITS水管ⅡA与前驱动电机的连接，排放前集成电力驱动电机内的冷却液。

4 Install the special sealed filling cap to the expansion tank.安装专用密封加注盖到膨胀箱。 Special Tools: Coolant Changing Equipment专用工具：冷却液更换设备   Caution:注意： ♦  Install the sealing cover correctly and in place to avoid air leakage due to loose sealing.正确安装密封盖并安装到位，避免因密封不严导致漏气。

5 Connect the compressed gas pipeline to any joint of the special sealed filling cap, and use compressed gas to blow out the remaining coolant in the system.连接压缩气体管路到专用密封加注盖任一接头，使用压缩气体吹出系统内残余冷却液。   Caution:注意： ♦  When turning on the compressed gas, keep the recovery container close to the battery outlet to prevent coolant from splashing.打开压缩气体时，使回收容器贴近电池出水口，谨防冷却液喷溅。 6 After the discharge is completed, connect the cooling water pipe and check that the cooling water pipe should be firmly connected.排放完毕后，连接冷却水管，检查冷却水管应连接牢固。

Filling procedure加注程序

1. Fill the battery temperature control system coolant1. 加注电池温控系统冷却液

1 Special sealing filling cap for connecting double row spring filling hose.连接双排弹簧加注软管专用密封加注盖。 Special Tools: Coolant Changing Equipment专用工具：冷却液更换设备

2 Connect the vacuum air extraction pipe A, coolant filling pipe B, and silicone water injection hose C to the corresponding air extraction, filling, and water injection interfaces on the coolant replacement equipment, and put the water inlet end of the silicone water injection hose into a container containing coolant.连接真空抽气管A、冷却液加注管B、硅胶注水软管C到冷却液更换设备上对应的抽气、加注、注水接口，将硅胶注水软管进水端放入盛有冷却液的容器内。 Coolant model: G30, -35℃冷却液型号：G30，-35℃ Coolant filling amount: 9.9~10.1L冷却液加注量：9.9~10.1L   Caution:注意： ♦  In order to avoid empty suction and facilitate replenishment, the volume of coolant in the container must be larger than the volume of coolant that needs to be filled.为避免空吸及方便补充，容器内的冷却液体积要大于需要加注的冷却液体积。 3 Connect the coolant replacement equipment to 220V AC power.连接冷却液更换设备到220V交流电源。

4 Turn on the power switch A (red light).打开电源开关A(红色灯)。

5 Click the "SET" button A to switch the unit, and click the up and down adjustment buttons to set the filling amount. Click "RUN/STOP" button B to start the quantitative control module, and the screen will remain on at this time.点击“SET”按钮A，切换单位，点击上下调整按钮设置加注量。点击“RUN/STOP”(运行/停止)按钮B，启动定量控制模块，此时屏幕保持常亮。

6 Turn on the start switch (green light), and the host begins to vacuum the system. When the pressure gauge reading reaches -90kPa, the vacuuming action automatically stops and automatic filling begins. The quantitative control display shows the instantaneous filling speed and amount. When the specified amount of coolant is added, the filling action automatically stops and the display dims.打开启动开关(绿色灯)，主机开始对系统进行抽真空，当压力表读数达到-90kPa时，抽真空动作自动停止，开始自动加注。定量控制显示屏显示瞬时加注速度与加注量，当加注到指定剂量的冷却液时，加注动作自动停止，显示屏变暗。   Caution:注意： ♦  During the filling process, pay attention to the remaining coolant in the container. If the liquid level is too low, replenish the coolant of the same specification in time.加注过程中注意容器内剩余冷却液，液面过低时应及时补充同种规格冷却液。

7 Turn on the reset switch (blue light), and the internal pipeline pressure of the host returns to atmospheric pressure. Open the drain valve under the buffer tank to drain the remaining coolant in the pipeline to the outside.打开复位开关(蓝色灯)，主机内部管路压力恢复至大气压。打开缓冲罐下方的排水阀，可将管路残留的冷却液排放到外部。   Note:提示： ♦  Releasing the pipeline pressure can avoid damage to the internal pipelines and pressure gauges caused by being in a vacuum state for a long time.释放管路压力，可避免内部管路及压力表因长期处于真空状态而导致损坏。 ♦  When the reset switch is turned on, the equipment cannot start the filling action.打开复位开关时，设备无法启动加注动作。

8 Disconnect the double row spring fill hose from the special sealed fill cap.断开双排弹簧加注软管与专用密封加注盖的连接。

9 Remove the special sealing cover.拆卸专用密封盖。 10 Use the scan tool to start the cooling system drain routine.使用诊断仪启动冷却系统排空例程。

11 After waiting for the draining routine to complete, check the coolant level and replenish the coolant level to the MAX line.等待排空例程完成后，检查冷却液液位，补充液位至MAX线处。 12 Install and tighten the filler cap.安装并拧紧加注口盖。 13 Check that the cooling system pipes and connections are in good condition.检查冷却系统管路及连接部位的状态应完好。
