The draper expert universal cooling system vacuum purge and refill set is a professional cooling system tool designed to eliminate air-locks and dramatically reduce refill time when servicing vehicle cooling systems. This vacuum-assisted filling system is ideal for mechanics and automotive technicians who need to service cooling systems efficiently without the time-consuming bleeding process. The kit operates by connecting to a workshop air line to create a vacuum within the cooling system, which then draws pre-mixed coolant through the filler hose smoothly and completely. This vacuum purge method ensures a thorough fill without trapped air pockets that can cause overheating issues or require repeated bleeding procedures. Supplied complete in a protective carrying case, the set includes a pressure gauge for monitoring the vacuum process, 1.3M of clear hose for visibility during filling, four adaptors to suit different radiator cap configurations, and a hose end filler. The universal design with multiple adaptors makes this kit suitable for a wide range of vehicle makes and models, providing professional workshops with a versatile solution for cooling system maintenance and repair work. Features and benefits: dramatically reduces cooling system refill time by preventing air-locks thus avoiding time-consuming cooling system bleeding plugs into air line then attaches to the cooling system to create a vacuum filler hose is then connected allowing pre-mixed coolant to flow eas...
