Compatible with ½" (12.7 mm), 5/8" (15.9 mm), and ¾" (19 mm) heater hoses, this back flush tool clears clogged heater cores using a standard garden hose connection. The corrosion-resistant aluminum construction allows for cooling system maintenance without vehicle disassembly or the use of caustic acids. This process restores flow to restricted components to prevent the need for complete heater core replacement.
