Coolant Vacuum Refill Kit Quick Vacuum Coolant Fill Kit with 5 Universal Adapters, Pressure Gauge, 41 in Fill Hose & 2 Quick Connectors for Most Vehicles
【ELIMINATES AIR POCKETS, SAVES TIME & PREVENTS OVERHEATING】This coolant refill kit create a vacuum to purge trapped air, ensuring bubble-free coolant circulation while monitoring pressure for leak detection. Compatible with air compressors (not included), it injects coolant rapidly under vacuum. The vacuum-driven flow removes air/impurities, stabilizes radiator performance, and prevents engine overheating or overcooling by maintaining optimal operating temperatures. Ideal for efficient coolant replacement, it cuts service time & reduces risks of poor circulation or engine damage.
【MULTI-SIZE ADAPTERS&PURPOSE】This coolant vacuum filler kit includes 2 quick-connect air fittings, 1 universal tapered rubber adapter , and 4 round adapters in varying sizes .It works with mainstream brands like Volkswagen, Ford, Audi, Honda, as well as SUVs, vans, and light trucks. The rubber adapters securely fit radiator openings, while the tapered adapter ensures high-seal performance with minimal contact area. (Note: Confirm radiator opening size matches the adapters before use.)
【HD PRESSURE GAUGE】This vacuum coolant refill tool features a rugged rubber-cased pressure gauge designed for impact resistance and drop protection. The screen clear visibility of dual-scale readings (-1~0 Bar / -76~0 cmHg), while its stable pointer enables precise pressure monitoring. It allows real-time tracking of tank pressure to ensure accurate coolant refills, complete radiator system supply efficiently, and quickly detect water tank leaks. The durable construction and protective rubber housing maintain reliable performance in demanding conditions.
【HIGH-QUALITY MATERIALS 】The coolant filling hose is 41-inch long, It can be quickly connected with tee fitting and hoses, saving refill time. . The rubber coolant filling hose is transparent and easy to observe. The other end of the hose is equipped with a filter, which can filter impurities to ensure the replenishment of clean coolant.Note: The suction inlet of the hose must be completely immersed in the new coolant to prevent air from entering.
【QUICK-CONNECT BRASS INTERFACE】The coolant vacuum refill tool adopts an integrated structure, high-hardness aluminum and brass for critical components (tee connectors, manifold body, control valves, and quick-connect fittings). The leak-proof sealed design prevents air leakage, while brass tee connectors enable rapid installation, accelerated vacuum creation, and precise coolant distribution to improve refill efficiency.
【EASY TO STORE AND CARRY】The kit includes a durable, lightweight toolbox with inlay storage for impact-resistant transport, organized component fixation, and safe long-term storage. Note: Always allow coolant to cool before servicing, wear protective gear, and handle pressurized systems cautiously to avoid hot coolant fluid spray.
