AUTOOL SC301 · Cooling System Vacuum Filler and Leak Tester
Test for Leaks, Then Vacuum-Fill Coolant
AUTOOL SC301 combines a vacuum-hold check and vacuum-assisted coolant filling for compatible cooling-system openings. Tester Mode draws one of three selected vacuum levels (-35, -40 or -45 kPa) and reports the 60-second hold status; Filler Mode adds coolant after vacuuming. The 12 V / 5 A unit requires an external air supply and one of the three matching conical adapters.

주요 특징
Switch Between Leak Test and Vacuum Fill
Vacuum-Hold Test + Vacuum Fill
Filler Mode removes residual air and refills coolant. Tester Mode checks cooling-system sealing by drawing a vacuum and monitoring it through the hold period.
Automatic Coolant Filling
After vacuuming is complete in Filling Mode, the machine automatically starts adding coolant to the cooling system.
Vacuum-Hold Status
In Tester Mode, the machine applies the selected vacuum and reports a hold status. Use that status to check the adapter seal, connections, and cooling system, then inspect the suspected area if the hold is not maintained.
Three Pressure Settings
Choose -35KPa, -40KPa, or -45KPa based on the working condition and vehicle configuration.
디지털 제어반
The panel separates Filling Mode and Leak Detection Mode, with digital display, pressure knob, working indicator, and start/stop buttons.
Red and Green Hold Status
The red or green indicator reports whether the connected setup maintained the selected vacuum during the model’s hold cycle. Recheck the adapter and hose seals before attributing a failed hold to the vehicle cooling system.
The red and green indicators report the model’s hold status for the selected check. Confirm the adapter and connection seal before treating a failed hold as evidence of a cooling-system leak.

자주 묻는 질문
Cooling-System Fit and Service Questions
Does SC301 Need An External Air Compressor?
Yes. SC301 requires an external air compressor connected to the air source input. A compressor rated around 0.7MPa or higher is recommended for proper operation.
Can I Power SC301 With 24V, 110V, Or 220V?
No. SC301 is designed for DC 12V power only. Using 24V, 110V, 220V, or 380V may damage the equipment.
Does The Vehicle Need To Be Started During Testing?
No. Vehicle ignition is not required for SC301 cooling system testing or coolant filling.
Which Pressure Level Should I Choose?

What Do The Red And Green Lights Mean?
In Testing Mode, the green light means no leakage is detected, while the red light means leakage is detected. The machine completes its vacuum-hold check and then provides the indication automatically.
The red/green display reports vacuum-hold status for the selected check. If the hold fails, inspect the adapter seal, connections, and cooling system for the leak area.
What Happens During Testing Mode?
After the correct vacuum level is selected and the Start/Stop button is pressed, the machine starts vacuuming. Once vacuuming is complete, it enters a 60-second vacuum-hold mode and then gives an automatic leak detection result.
What Should I Do If The Selected Vacuum Level Cannot Be Maintained?
If the selected vacuum level cannot be achieved and maintained in Testing Mode, SC301 switches to its vacuum-hold mode within two minutes and displays a fault reminder. Check the cooling system connection, adapter sealing, hoses, and possible leak points before testing again.
What Happens During Filling Mode?
In Filling Mode, choose the suitable gear, press Start/Pause, and the machine begins vacuuming the cooling system. After vacuuming is complete, coolant is automatically filled into the system. If filling is not complete, multiple filling cycles can be performed.
What Should I Do If Coolant Does Not Enter During Filling Mode?
If no coolant enters the system within two minutes during Filling Mode, SC301 displays a fault reminder. Check whether the coolant inlet hose is placed correctly in the coolant container, whether the adapter is sealed, whether the drain valve is in the correct position, and whether the air compressor is connected properly.
