Perform a complete cooling system flush by using clean water and compressed air with the Gates Corp. Powerclean Flush Tool. This tool “water hammers” accumulated sludge and scale deposits without the use of harsh chemicals or solvents. It cleans radiators, heat exchangers, hoses and engine blocks more effectively than conventional flushes, according to the company. This helps to maintain a system's integrity and ensures warranty coverage on replacement parts, including water pumps. The Powerclean Flush Tool’s patented process uses fixed dimensional control of the air and liquid flow paths. The process allows air to pressurize the water, creating a pulsating action to scrub deep into corners and crevices, eliminating trapped debris. This tool includes a pulsating gun assembly with pre-set regulator, water line backflow preventer, large rubber tip for radiator necks and direct flushing of the engine block, small rubber tip on whip hose for direct access to heater core tube stubs, and 5/8” and 3/4” heater hose barbs for flushing heater cores or engine blocks, all in a durable protective storage case with room for additional items.
