防冻液打压流程
  The process of pressurizing antifreeze fluid typically involves the following steps:
 
  Preparation: Ensure that the antifreeze fluid is at the appropriate temperature and properly mixed according to the manufacturer's instructions. This ensures optimal performance and protection against freezing.
 
  Check the System: Inspect the cooling system to ensure there are no leaks or other issues that could affect the pressurization process. Repair any leaks or address any other problems before proceeding.

  Pressure Testing: Use a pressure testing tool or gauge to measure the current pressure in t
he cooling system. This will serve as a baseline for comparison after pressurization.
 
  System Connection: Connect a pressurization device, such as a hand pump or air compressor, to the radiator or coolant reservoir. Ensure the connection is secure and airtight.
 
  Pressurization: Gradually increase the pressure using the pressurizing device. Refer to the manufacturer's guidelines or the vehicle's specifications to determine the recommended pressure level.
 
  Pressure Measurement: Monitor the pressure gauge as the system is being pressurized. Stop increasing the pressure once it reaches the desired level.
 
  Pressure Holding: Keep the pressurization device connected for a short period to observe if the pressure drops significantly. If there is a significant pressure drop, it indicates a possible leak that needs to be addressed.
 
  Release Pressure: Release the pressure in the cooling system by slowly disconnecting the pressurization device. Ensure that the pressure is fully released before opening any cooling system components.
 
  Final Pressure Check: Use the pressure testing tool or gauge again to measure the pressure in the cooling system. Compare it to the baseline reading taken before pressurization to ensure there are no significant changes and that the system is properly pressurized.
 
  防冻液打压的过程通常包括以下步骤：
 
  准备：确保防冻液的温度适宜，并按照制造商的说明正确混合。这样可以确保防冻液在低温下具有最佳的性能和防冻保护。
 
  检查系统：检查冷却系统，确保没有泄漏或其他可能影响打压过程的问题。在继续之前修复任何泄漏或解决其他问题。
 
  打压测试：使用打压测试工具或压力计测量冷却系统中的当前压力。这将作为打压后对比的基准。
 
  系统连接：将打压工具（如手动泵或空气压缩机）连接到散热器或冷却液储存罐。确保连接安全且密封良好。
 
  打压：使用打压设备逐渐增加压力。根据制造商的指南或车辆的规格要求确定推荐的压力水平。
 
  压力测量：在系统打压过程中，监测压力计的读数。一旦达到所需的压力水平，停止增加压力。
 
  保持压力：保持打压设备连接一段时间，观察压力是否显著下降。如果压力显著下降，可能表示存在泄漏问题需要解决。
 
  释放压力：缓慢断开打压设备的连接，释放冷却系统中的压力。确保完全释放压力后再打开任何冷却系统部件。
 
  最终压力检查：再次使用打压测试工具或压力计测量冷却系统中的压力。将其与打压前的基准读数进行对比，确保没有显著的变化，并且系统已经正确打压。
