then secured in place with a tube tightening means e g a locking wing nut the pumping apparatus is then started whereby liquid contents are removed from the system until the over flow container is substantially empty although a flushing step cleaning step is not required it is preferable to use a cleaning flush to clean the radiator of rust and other matter a flushing agent such as those commercially available is placed in the over flow container the pumping apparatus is started and the flushing agent drained into the radiator the pumping apparatus is stopped once the flushing agent empties from the over flow container the engine is then started and run for about one to ten minutes preferably about five minutes the engine is then stopped and the pumping apparatus operated to remove the liquid from the radiator until the liquid pumping from the radiator is complete e g as indicated by having substantially no liquid draining from a drain outlet of the pumping apparatus the system is now flushed with water via introduction of water from the pumping apparatus the system is deemed full when the recovery bottle starts to fill with water when the system is full the introduction of water is stopped and the engine is started and run for about one to about 4 minutes preferably about two minutes the water is removed from the system by the pumping apparatus in the same manner as the old coolant flushing agent was removed the concentration of antifreeze coolant for the system is determined and the appropriate amount concentration of antifreeze coolant placed into the reservoir of a pumping apparatus and pumped into the automobile cooling system once the antifreeze coolant has.
