  • 【Find Leaks Fast – Green Light = No Leak, Red Light = Leak】Stop guessing. Switch to Tester Mode, press start, and the SC301 instantly detects micro-leaks in hoses, pipelines, and heater cores. Green light and “NO LEAKAGE” mean your system is sealed. Red light and “Err” mean you found the problem. No complicated interpretation needed.
  • 【Vacuum Fill – No Air Pockets, No Overheating】Air trapped in your cooling system causes localized overheating and engine damage. Switch to Filler Mode, press start, and the SC301 vacuums out all residual air, then automatically fills with fresh coolant. When it’s done, it stops itself and beeps. Hands-free, worry-free.
  • 【3 Pressure Levels + Built-In Burst Protection】Choose from -35 kPa, -40 kPa, or -45 kPa to match your vehicle’s age. The built-in pressure protection prevents over-vacuuming, so you won’t risk bursting old hoses or the coolant reservoir. Safer for older vehicles, precise for newer ones.
  • 【Fits Most Cars, Trucks & SUVs – 3 Adapters Included】Comes with three types of adapter fittings covering sizes from 16mm to 70mm (33mm/41mm/52mm and 16mm/23mm/34mm). No need to buy extra parts. Includes 2m filling hose, 1m air hose, and 0.5m input hose for flexible reach.
  • 【Easy Cleanup – Built-In Liquid Drain Valve】After each use, open the drain valve to empty residual coolant from the internal lines. Prevents mixing different coolants and keeps the tool ready for next time. Simple maintenance that extends tool life.
  • 【Three Years Warranty and Lifelong Maintenance】For the damage caused by non-human factors, we promises to resend the parts for free within 3 years. For any demand, we warmly welcome you to contact us, and we will reply you as soon as possible within 24 hours.
