ABSTRACT:
An apparatus and method for changing the antifreeze in a vehicle requires only a garden hose and opening of the radiator cap. Water from the hose is utilized to prime a conduit for siphoning used coolant from a side tank radiator and for refilling the radiator. By operating the vehicle with fresh water in the radiator, coolant remaining in the system is mixed with the water, and repeated drainings decrease the remaining used antifreeze by about one-half each time. After removal of the desired amount of antifreeze, new antifreeze may be placed in the radiator.
