REMOVAL & INSTALLATION
See Figures 1 and 2
The freeze plugs can be loosened and removed using a punch and a hammer. Or, drill a small hole in the middle of the freeze plug, then thread a large sheet metal screw into the hole. Remove the plug with a slide hammer. When installing, coat the freeze plugs with sealer. Tap into position using a piece of pipe, slightly smaller than the plug, as a driver.
