AUTOOL SC301 Automotive Coolant Leak Detector and Filler

AUTOOL SC301 Coolant Leak Detector & Filler

The AUTOOL SC301 combines cooling system leak testing, vacuum filling and coolant recovery in one workshop machine. It helps technicians find cooling system leaks and refill the system with less trapped air after servicing or repair, and a single operator can do the whole job.

Who It Suits

Workshops that service cooling systems and want a faster, more controlled way to leak test and refill coolant.

Key Features

• Leak detection mode uses vacuum extraction and pressure holding to determine whether the system leaks
• Coolant filling mode refills the system under vacuum
• Clear LED results – solid red means a leak, solid green means no leakage
• Digital display window shows the data clearly
• Safety protection – automatically stops and moves to the next step once the vacuum reaches the set pressure, protecting the cooling system
• Liquid drainage design lets residual coolant drain from the internal pipes at the end of the job
• Three vacuum levels – -35kPa, -40kPa and -45kPa to suit vehicle type, age or condition
• Three conical adapter sizes covering most European, American and Asian vehicles
• Audio and visual alerts with a simple control panel
• One-person operation, high degree of automation
• 12V battery powered; uses a workshop air compressor connection
