BILITOOLS Coolant Funnel Kit, Automotive Radiator Coolant Filling Tool | No-Spill Universal Radiator Cooling System Bleeding Burping Tool Kit with Vent Tube

Features

• Coolant Refill & Bleeding ToolDesigned for refilling, topping off, and bleeding automotive cooling systems after coolant changes, radiator service, thermostat replacement, or coolant flush work. Helps keep coolant supplied above the fill point while trapped air escapes. For quick, easy coolant filling on a wide range of cars & vans.
• Less Splashback, Cleaner Engine BayThe Coolant funnel form and pressure-balancing vent tube work together to help reduce coolant overflow, bubbling, and splashback. This helps keep coolant away from belts and surrounding engine components while making refills cleaner and easier to manage.
• Shut-Off Valve for Flow ControlBuilt-in shut-off valve lets you pause or control coolant flow during service. It helps reduce overfilling, backflow, and coolant spillage when the system level rises or when removing the funnel after refilling.
• Extension Pipe & Angled AdaptersThe 45-degree adapters help reach tight engine bay spaces, recessed filler necks, and angled coolant tank openings. ABS plastic construction keeps the adapters lightweight, easy to handle, and resistant to rust.
• Multiple Size AdaptersIncludes 31 mm, 35 mm, 40 mm, 42 mm, 45 mm rubber adapters and a tapered universal adapter for different radiator filler necks. Choose the closest fit, then use the twist-lock mechanism to expand the adapter for a more stable connection.
