Car Radiator Coolant Refill Purging Kit, Vacuum Cooling System Tool, Fast Connector for Leak Test and Air Evacuation, Compatible with Automotive Cooling Systems

Item Type: Coolant Refill KitMaterial: Stainless Steel + RubberApplication: Coolant replacementFeatures:Principle of Use: The cooling liquid is sucked into the water tank by vacuuming the inside of the water tank to generate negative pressure.In order to prevent the internal temperature of the engine from being too high due to air resistance in the cooling system pipeline when filling and replacing the coolant, vacuum filling must be used, and at the same time, it can reduce the maintenance time and is convenient and quick.How to Use:1. Clear the water in the water tank2. Open the car hood and hang the hook in the appropriate position3. Connect the universal rubber joint to the water tank4. Make sure all switches are turned off, and connect the thin tube to the tail of the 5. Connect the intake pipe and press the yellow switch button to turn on the intake switch for vacuum treatment. When the pressure reaches -20--25Inhg (-50--60cmhg), turn off the NO.3 switch6. Connect the antifreeze hose to the car body, and put the other end into the antifreeze container. The interface must be completely immersed below the water level. Turn on the water level switch to automatically add the antifreeze to the water tank.Package List：1 Set of Coolant Refill Kit (7pcs)1 BoxNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
