The Jimy Tools 26 piece cooling system tester and vacuum type refilling kit helps you to diagnose problems with your cooling system. Test the operation of your radiator cap with the 2 double ended adapters or pressurise the cooling system to check for leaking hoses, leaking radiator, cracks in header tanks or more significant problems like water pump seal failure, blown head gasket or cracked head. Also included is a compressed air operated vacuum type cooling system purge and refill tool which will eliminate trapped air by purging and refilling the cooling system under vacuum.


Using a suitable adapter or the universal cone shaped adapter attach the vacuum tool to the filler neck of the radiator or header tank if fitted (on some vehicles fitted with an overflow tank, it may be necessary to clamp the overflow hose) connect the air supply and open the valve allow the vacuum level to reach approximately 20-25inHg (50-60cmHg) then close the valve. During this procedure the radiator hoses will collapse under the vacuum being generated, this is normal. Turn off and disconnect the air supply, check the gauge over the next 3 minutes. If the gauge reading drops there is a system leak which will require locating and rectifying before proceeding further. Place the filler hose into the container of coolant make sure that the end of the hose remains submerged throughout the filling process and connect the other end of the hose into the coolant hose connector Open the valve fully and coolant will flow into the cooling system. For best results raise the coolant container above the level of the filler neck. When the gauge reads ‘0’ turn the valve to the off position and remove tool from the filler neck. If necessary top-up the coolant to the specified level and refit the pressure cap. The system is filled and free from air locks. Start the engine and run until normal operating temperature is reached. Allow to cool and top-up coolant if necessary.
