Quick Bleed Kit for Car Radiator - Drain Connector, Leak Test and Vacuum for Cooling System

This coolant filling kit allows you to quickly and efficiently drain and refill your vehicle's cooling system. Designed to significantly reduce intervention time, it prevents air from entering the system, ensuring optimal operation. Made from high-quality stainless steel and rubber, this kit is robust and durable. Its operating principle is based on creating a vacuum in the reservoir (or expansion tank), generating negative pressure that draws in the new premixed coolant. This vacuum filling method is essential to prevent air pockets in the lines, which could lead to engine overheating. The kit is simple and practical to use: - It easily connects to a compressed air source (workshop air pump) to create a vacuum on the fill hose. - The quick-connect fitting allows for easy installation and removal, saving valuable time. - After creating a vacuum, simply open the valve to allow the coolant to flow through the system in a controlled and bubble-free manner. - It also allows for leak testing of the cooling system. The typical procedure includes draining the system, attaching the kit under the hood, connecting the universal joint to the expansion tank, creating a vacuum until a pressure of approximately -20 to -25 inHg is reached, and then connecting the hose to the container of new coolant. for automatic filling.
