AUTOOL SC301 Automotive Coolant Leak Detector and Filler

The AUTOOL SC301 is a 2-in-1 automotive cooling system tester and coolant vacuum filler for cooling system vacuuming, coolant filling, and pressure leak detection. It uses vacuum extraction and pressure-holding detection to help users check cooling system sealing, remove air pockets, and refill coolant more efficiently with one-person operation. Confirm the power supply, air compressor, coolant type, radiator temperature, and drain-valve position before testing or filling a cooling system. SC301 combines leak detection, coolant vacuuming, automatic filling, adjustable pressure levels, clear leak indicators, and adapter-based vehicle compatibility in one automated cooling system service tool. SC301 is designed for automotive cooling system leak detection and coolant filling. The included adapter fittings help fit many common coolant reservoir openings, but vehicle fitment should still be confirmed before use. Follow the setup order, select Testing Mode or Filling Mode, use the correct pressure level, and drain residual coolant safely after service. Review the SC301 power, pressure, hose length, dimensions, adapter, and interface information before operation. Key features • Dual Modes: Filler mode and leak detection mode let buyers handle coolant filling and leak checks with one machine. • Three Pressures: Selectable -35kPa, -40kPa, and -45kPa settings help match vacuum level to different vehicle conditions. • Leak Indicators: Red and green LED indicators make leak status easier to confirm without interpreting complex data. • Product: AUTOOL SC301 Cooling System Tester & Filler • Main Functions: Cooling system vacuuming, coolant filling, and pressure leak detection • Power Supply: DC 12V
