ABSTRACT:
A freeze plug installation tool kit includes a drive tool having a coupling ball and a plurality of selectable carrier heads respectively sized for mating engagement with different-sized freeze plugs and detachably mountable on the coupling ball. Each carrier head has a cylindrical socket with an annular groove in which a split ring is disposed for snap engagement with the coupling ball to retain the ball in the socket. A flexible disk in the socket cooperates with the split ring to limit movement of the ball when it is retained in the socket.
