An installation tool for installing a cup-shaped freeze plug in an engine block's bore. A reciprocable hammer nose connectable to a power source repetitively hammers the freeze plug to drive it into the bore. One feature includes a hammer stroke adjustment system which permits the stroke depth of the hammer nose into the block's bore to be adjusted by the tool's user in order to seat the plug at a pre-determined depth in the bore. Another feature includes a housing particularly sized and configure to cooperate with a freeze plug of the type having a minor diameter base section adapted to be slip fit into the block's bore and a major diameter rim section adapted to be pres fit into the bore, the plug's rim being received internally of the housing when the plug's base is slip fit into the bore, and when the housing is engaged with the outer surface of the engine block so as to align the plug and the tool and the bore properly prior to hammering the plug's rim into the bore. |
