How you repair a radiator depends on what is wrong with it. A small leak may be able to be fixed by adding a stop-leak product, available at most discount stores and auto repair retailers. Depending on the problem, the radiator may have to be pulled from the vehicle for inspection. Minor damaged can perhaps be fixed with a stop-leak product or a small spot weld if the radiator is copper or brass. Aluminum radiators (newer models) can sometimes be repaired with epoxy.
Stop leak products for the radiator from auto supply stores are not meant as a long-term solution. They should only be used to get you home or to a mechanic who can repair or replace the radiator properly.
