【Complete Heater Core Flush Kit for Cooling System Cleaning】 This heater core flush kit includes a coolant flush gun, 5/8" & 3/4" hose adapters, American & European air fittings, and PTFE thread seal tape to help clean radiator, heater core, and cooling systems efficiently. The complete setup provides the essential components needed for professional-style coolant system flushing. 【Powerful Air & Water Flushing Performance】 The coolant flush gun combines compressed air and water flow to create a powerful flushing action, helping break down and remove rust, scale, dirt, and contaminants trapped inside heater cores and cooling passages. It helps restore coolant circulation and heating performance. 【Wide Hose & Vehicle Compatibility】 The heater core flush kit supports 5/8" and 3/4" garden hose adapters, as well as 1/4" American & European dual standards available air fitting, providing flexible connection options for different flushing setups. It includes 5 coolant hose adapters: 0.75" (19 mm), 1.14" ( 29mm), 1.26" (30 mm), 1.44" (37 mm), and 1.57" (40 mm) to fit various vehicle cooling system hose openings. 【Adjustable Trigger Control with Locking Function】 The ergonomic trigger design allows precise control of water flow and flushing pressure. The built-in locking latch keeps the coolant flush gun operating continuously without constant hand pressure, reducing fatigue during extended cleaning jobs. 【Quick Setup with Air and Water Connections】 Simply connect the garden hose and air line to the corresponding inlets, install the matching nozzle, and start flushing. The included adapters and PTFE sealing tape help create secure connections while minimizing leaks during operation.
