ABSTRACT:
A tool with a body member which can be braced between the engine block and an adjacent wall of the automobile has a sharp-pointed member movable under the control of a hand operated lever arm to penetrate a freeze plug in the engine block and become wedged in the plug so on reverse movement of the lever arm the plug is removed from the engine block. For use in inserting a new plug, the sharp-pointed member is replaced by a flat headed one which drives a new freeze plug into the appropriate block opening on appropriate operation of the lever arm.
