What is a coolant flush and recycle machine, and why would I need one?

A coolant flush and recycle machine is designed to efficiently remove old coolant from a vehicle's cooling system, clean the system, and often recycle the removed coolant. This is important for maintaining optimal engine temperature, preventing corrosion, and extending the life of cooling system components like radiators and water pumps. Regular coolant flushes, aided by these machines, help prevent overheating and costly repairs. Some machines also offer features like vacuum filling to eliminate air pockets in the cooling system.

How do vacuum-style coolant refill tools work, and what are their benefits?

Vacuum coolant refill tools, like the UView Vacuum Antifreeze Drain and Fill, create a vacuum within the cooling system before refilling. This vacuum ensures that the system is free of air pockets, which can impede coolant flow and cause overheating. These tools connect to the cooling system, create a vacuum using shop air, and then draw coolant back into the system. The primary benefit is a complete and air-free coolant fill, leading to more efficient cooling and preventing potential engine damage.

What is a coolant supply tank used for, and what capacity should I consider?

A coolant supply tank, such as the Robinair 7-Gallon Coolant Supply Tank, is a reservoir for holding new coolant during a flush and fill procedure. This allows for a continuous and clean supply of coolant, especially when using a coolant exchange machine. The appropriate capacity depends on the vehicles you service; passenger cars typically require less coolant than trucks or heavy-duty equipment. Choose a tank size that comfortably exceeds the typical coolant capacity of the vehicles you service to avoid interruptions during the flush.

What are the different types of coolant flush chemicals, and when should each be used?

Coolant flush chemicals typically fall into two categories: mild detergents and stronger chemical cleaners. Mild detergents are suitable for routine maintenance and removing light deposits. Stronger chemical cleaners are designed for heavily contaminated systems with rust or scale buildup. Always follow the manufacturer's instructions and safety precautions when using any coolant flush chemical. Consider the age and condition of the cooling system when selecting a cleaner; avoid harsh chemicals on older systems that may have weakened components.

What maintenance is required for coolant flush and recycle equipment?

Regular maintenance is crucial for ensuring the longevity and performance of coolant flush and recycle equipment. This typically includes regularly changing filters to remove contaminants from the recycled coolant, as seen with the Robinair 20 Micron Replacement Filters. Also, inspect hoses and connections for leaks or damage, and clean the machine's internal components according to the manufacturer's recommendations. Proper maintenance prevents breakdowns and ensures accurate coolant recycling.

Can a multipurpose cleaning gun be used in cooling system maintenance?

Yes, a multipurpose cleaning gun like the OTC Tools & Equipment Blast-Vac can be useful for cleaning cooling system components. It can be used to blow out debris from radiators, heater cores, and other parts. When using a cleaning gun, always wear appropriate safety gear, including eye protection, and avoid directing high-pressure air at sensitive components. Verify that the cleaning gun is compatible with the materials being cleaned to prevent damage.

Are coolant flush machines suitable for all types of vehicles and coolant?

While most coolant flush machines are designed to be compatible with a wide range of vehicles, it's essential to verify compatibility with specific vehicle makes and models, especially those with unique cooling system designs. Also, different coolants (e.g., conventional, OAT, HOAT) have different chemical compositions, and some machines may not be suitable for all types. Consult the machine's documentation and the vehicle's service manual to ensure compatibility before use.

Specifications

The Robinair AF Pro Coolant Exchanger, model {manufacturers_part_number}, is engineered for professional automotive coolant system maintenance. This heavy-duty unit operates on both 12V DC power and compressed air, requiring a minimum of 75 PSI at 5 CFM for efficient operation. It features an internal 15-gallon waste tank and two removable 5-gallon external supply tanks for new coolant. The unit has a shipping weight of 185.00 pounds and stands 47 inches high, 26 inches wide, and 33 inches deep (119 cm x 66 cm x 84 cm). Included are two medium step adapters, fitting hose sizes 1-1/4", 1-3/8", and 1-1/2", and two large step adapters for hose sizes 1-3/4", 2", and 2-1/4".

Key Features

Integrated Coolant Exchange: The system efficiently removes and replaces used coolant in a single, streamlined process.
Vacuum Fill Capability: A vacuum fill process facilitates adding new coolant, which helps eliminate air bubbles from the cooling system.
Leak Detection: Integrated pressure tests allow technicians to identify existing leaks in the cooling system before refilling.
Engine-Off Operation: The "Engine Off" feature enhances safety by removing pulleys, belts, and fan blades from the operational equation during service.
Rapid Exchange Process: Conducts a complete coolant exchange within approximately 10 minutes, reducing service time significantly.
Vacuum Mode Safety: Utilizes a "push/pull" vacuum mode for safely removing high pressure from hot cooling systems.
User-Friendly Interface: Features two clearly marked valves and an easy-to-read gauge for straightforward operation.
Durable Construction: Built with an impact-resistant polypropylene cabinet that resists scratching, denting, and common shop chemicals.
On-Board Storage: Offers on-board storage for two distinct coolant types via external tanks and includes dedicated storage for step adapters.
Hose Management: Equipped with 96-inch hoses that can be neatly stored on the unit.

Applications

The AF Pro Coolant Exchanger is designed for comprehensive coolant system service in professional automotive repair environments. It is suitable for use on all passenger cars, as well as light and medium-duty trucks. This equipment supports essential cooling system maintenance tasks, including flushing old coolant, refilling with new coolant, and performing leak checks to ensure system integrity.

Benefits

Time and Cost Efficiency: Reduces the time required for a typical drain and fill by at least 50%, optimizing shop productivity and reducing labor costs.
Enhanced Safety: The "Engine Off" feature minimizes risks associated with rotating engine components, while vacuum mode safely manages high-pressure systems. "Hands-off" transfer of used coolant further protects technicians from spills.
Improved System Performance: Ensures complete coolant replacement, eliminating air pockets and helping to extend the operational life of a vehicle's cooling system.
Reduced Contamination: Minimizes the potential for cross-contamination between different coolant types, preserving system integrity.
Ease of Use: Simple operation with clearly marked controls means minimal training is required for technicians to perform coolant exchanges effectively.
Portability and Durability: Large, inflatable tires and a robust cabinet allow for easy maneuverability across shop floors and withstand demanding work environments.
