Pneumatic Vacuum Coolant Filling Tool Kit Efficiently fill and service vehicle cooling systems with this pneumatic vacuum coolant filling tool kit. Designed for professional and DIY automotive maintenance, it uses air to draw a vacuum in the cooling system, then pulls in coolant quickly and cleanly. The vacuumfill method prevents air pockets, reduces cavitation, and protects against engine damage. Typical fill time is just 5 to 10 minutes, depending on the size of the radiator or water tank. Key Features and Benefits: Fast, Air Coolant Filling Uses air to create a vacuum in the cooling system before drawing coolant in, eliminating trapped air and ensuring consistent fill levels. Prevents common problems such as overheating and premature component wear. Broad Vehicle Compatibility Includes a universal conical rubber adapter (1.5 to 5 cm diameter) that fits securely in place of most radiator caps. Works with almost all passenger cars, light trucks, SUVs, and many motorcycles, making it versatile for shops and home garages. Easy Connect and Use Equipped with a quick connector for fast attachment to air supply. The universal adapter seals tightly to the cooling system for efficient vacuum creation without leaks. Comprehensive Accessories Supplied with both European and American style gas plugs for compatibility with various air systems. The tool comes prefitted with an American style gas plug for immediate use, while the European connector is included for alternative setups. Precision Measurement Features a vacuum gauge with a range from 30 to 0 inHg (76 to 0 cmHg). The recommended range of 25 to 20 inHg ensures correct coolant draw time, enabling accurate and reliable operation every time. Durable, Quality Construction Built with a grade brass manifold body and brass fittings for corrosion resistance and longevity. Includes an 18inch reinforced rubber resin braided hose for durability under pressure, low fluid resistance, and lasting flexibility. A sturdy 21inch metal chain hook allows secure hanging from the vehicle hood during use. Applications and Use Scenarios: 1. Routine coolant replacement in passenger cars, ensuring air fill and maintaining cooling performance. 2. Engine rebuild or scenarios where the cooling system has been fully drained, enabling rapid and accurate refilling. 3. Fleet maintenance operations requiring consistent, fast, and reliable coolant servicing across multiple vehicle types. With its combination of speed, accuracy, and durability, this pneumatic vacuum coolant filling tool kit is a dependable solution for professional mechanics and serious automotive enthusiasts seeking reliable coolant service without the risk of trapped air or system damage.
