ABSTRACT:
The tool assembly enables installation in and removal from a combustion engine block of freeze plugs. The puller component has a plug penetrating point which is forced through the plug to define an opening. Spreader segments associated with the point can be spread laterally into engagement with the edge of the opening. Means are provided for imposing a retraction force on the segments, which cooperate to pull the plug free. A fresh plug is inserted in the freeze plug opening by utilization of an installer head shaped to releasably hold the plug during insertion in the opening after which the head can be withdrawn. Special leverage and force application arrangements are associated with the puller and installer head.
