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.

A method for changing coolant in the cooling system of a vehicle having a side tank radiator, with a radiator cap to close a radiator cap opening, comprising the steps of: (a) inserting a first end of conduit means into the vehicle radiator through the radiator cap opening without forming a sealed connection, said unsealed insertion of said conduit means being the only required contact of an operator with the vehicle cooling system; (b) extending a second end of said conduit means to a disposal means, said second end being located at or below the level of said first end; (c) connecting a source of water to said conduit means intermediate said first and second ends; (d) causing water from said source to flow into said conduit means to prime said conduit means for siphoning liquid from the radiator; and (e) discontinuing the flow of water into said conduit means so that the contents of the radiator are siphoned to said disposal means.
