AUTOOL SC301<\/div>\n

Product Overview<\/h2>\n

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.<\/p>\n

Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

Confirm the power supply, air compressor, coolant type, radiator temperature, and drain-valve position before testing or filling a cooling system.<\/p>\n <\/div>\n

\n
\n

DC 12V Only<\/h3>\n

Use a car battery or DC 12V power supply. Do not connect the SC301 to 24V, 110V, 220V, or 380V power.<\/p>\n <\/article>\n

\n

Air Compressor Required<\/h3>\n

Connect the air inlet hose to an external air compressor. A compressor rated around 0.7MPa or higher is recommended before operation.<\/p>\n <\/article>\n

\n

Vehicle Ignition Not Required<\/h3>\n

The cooling system test and coolant filling process does not require starting the vehicle.<\/p>\n <\/article>\n

\n

Cool Before Opening<\/h3>\n

Before opening the radiator cap or coolant reservoir, make sure the radiator and cooling system have cooled down.<\/p>\n <\/article>\n

\n

Use Suitable Coolant<\/h3>\n

Avoid low-quality coolant. Do not mix coolants with different performance specifications, and do not add undiluted coolant directly in low-temperature conditions.<\/p>\n <\/article>\n

\n

Use Lower Pressure For Older Vehicles<\/h3>\n

For older vehicles or aging cooling system parts, choose a lower pressure level instead of higher settings.<\/p>\n <\/article>\n <\/div>\n
