Why you need the AUTOOL SC301 Cooling System Tester &filler？ ⭐Innovative technology and automation: AUTOOL SC301 integrates innovative leak detection and filling technology, which allows users to start the automated process with simple operation, significantly saving time and effort, and greatly improving work efficiency. ⭐Powerful Leak Detection: Vacuum and pressure holding tests determine whether the cooling system is leaking and provide a visual display with LED indicators, making it easy for users to identify and repair leaks in a timely manner to ensure proper operation of the cooling system. ⭐Accurate and efficient refilling: switch to refilling mode after leakage detection, select the vacuum extraction gear, and then the system will automatically refill the coolant after the end of the process, without the need for further leakage detection. Make sure the connection is stable before operation, and the device will sound to indicate the completion of refilling after the vacuum pumping is completed. ⭐Simple and easy-to-use operation: AUTOOL SC301 is simple in design, equipped with intuitive sound and light prompts and an operation panel, which makes it easy for a single operator to complete the task of leak checking and refilling without specialized skills. ⭐Pressure protection saves time and money: The pressure level limitation provides pressure protection for the cooling system piping, preventing damage to the piping due to excessive vacuuming. Compared to conventional tools, the AUTOOL SC301 is much more efficient when refilling coolant, resulting in significant time and additional cost savings. |

| Smart Control Panel👍 The SC301 cooling system tester offers dual-function mode, integrating two modes of filling and leakage detection. The control panel is designed with simplicity in mind, featuring LED indicators and a digital display that make operation intuitive and straightforward, even for non-professionals. This enhances work efficiency. | Leak Detection Mode👍 The SC301 offers a comprehensive cooling system inspection with an integrated advanced pressure leak detection system that can detect the smallest leaks and eliminate potential safety hazards in a timely manner. It covers critical areas such as main cooling system pipes, engine coolant hoses and heater cores, helping to prevent cooling system failures due to leaks. | Three Pressure Levels Three pressure levels are available: -35KPa, -40KPa and -45KPa. Users can select the appropriate pressure level according to the specific working conditions, which provides comprehensive coverage for the inspection needs of different vehicle models. For older vehicles, we recommend the use of lower gears. | ||||
