From “Top-Up” to “Full Exchange” – AUTOOL Redefines Coolant Maintenance

Old Service Logic

Traditional coolant maintenance often solves only the question of how to add coolant. It may not fully remove old fluid, scale, rust, or impurities from the cooling system.

New Service Logic

A coolant exchange machine uses equal volume exchange and circulation cleaning to replace old fluid more thoroughly, improve service quality, and provide customers with a visible difference between new and old coolant.

AUTOOL SC501 Smart Cooling System Flush & Exchange Machine

• Circulation Flush FunctionEffectively removes scale, rust, and other impurities to improve heat dissipation efficiency and extend cooling system life.
• Equal Exchange TechnologySimultaneously fills new fluid while recovering old fluid, achieving an exchange rate of nearly 100%.
• Mechanical Knob ControlSimple and intuitive operation with no special training required.
• Pressure Overload ProtectionPrevents excessive pressure from damaging the vehicle's cooling system.
• New/Old Fluid Comparison WindowTransparent hoses with sight glass allow visual confirmation of exchange quality.
• 25L Large-Capacity TanksMeets the demands of continuous workshop use.
• Quiet Operation DesignMinimal noise during operation supports a better working environment.

AUTOOL SC611 Smart Fully Automatic Cooling System Flush & Exchange Machine

• One-Button Fully Automatic ExchangeAutomatically completes the coolant exchange process without repeated manual intervention.
• Vacuum Hold Pressure ModeCreates a vacuum and performs a pressure-holding test to check for leaks in the cooling system.
• Vacuum Fill ModeVacuum-assisted filling helps prevent air pockets, especially on high-end and new energy vehicles with complex cooling layouts.
• Precise Flow ControlControls flow rate and pressure during exchange to prevent cooling system damage.
• Circulation Flush and ProtectionRemoves scale, rust, and impurities while keeping pressure overload protection active.
• Real-Time Fluid Level Display25L tanks and clear level display show new and old fluid levels.

VS Traditional Vacuum Filling Tools

Traditional vacuum tools can only assist with filling. They cannot extract old coolant or flush the system. In essence, they solve the problem of how to add coolant, not how to change it thoroughly.

AUTOOL SC501/SC611 deliver professional-grade maintenance through active old coolant extraction, equal exchange technology, nearly 100% exchange rate, circulation flush, and electric pump design that requires no external air compressor.

VS Other Brand Exchange Machines

• Large Capacity + Low Power Consumption25L tanks compared with common 20L competitor tanks, with 15W power consumption compared with many 60W+ designs.
• More Practical Power SupplyAC independent power avoids relying on vehicle batteries and supports fixed workstation use.
• Leading Vacuum TechnologySC611 integrates vacuum hold pressure testing and vacuum filling for high-end and new energy vehicles.
• Outstanding Cost PerformanceSC501 uses mechanical knob control and affordable positioning to cover mainstream fuel vehicles.

Choose SC301 When

Your main need is coolant filling, vacuum testing, and pressure leak testing for mainstream fuel vehicles, and full circulation flushing is not the primary service item.

Choose SC501 When

You want to move from simple drain + refill service to deep cleaning and equal volume replacement for mainstream fuel vehicles, while keeping operation simple through mechanical knob control.

Choose SC611 When

You service high-end vehicles, new energy vehicles, or complex cooling system layouts that benefit from one-button full automatic exchange, vacuum hold pressure testing, vacuum filling, and precise flow control.
