sometimes it is cheaper to go with the new radiator, but when it isn't i am lucky to have a quality radiator shop nearby. kell radiator in douglasville, ga will replace leaking and broken plastic tanks or build you new aluminum tanks. they also repair oil and transmission coolers and a/c condensers and evaporators. i am not affiliated with kell radiator in any way, but i thought any members in the area should know about such a quality shop
