I wouldn t recommend trying this yourself. Find a guy with a hoist to get vehicle up in the air. And instead of putting in a typical frost plug, although inexpensive to purchase, would be difficult to put in with rust and cleaning and pressing in. Just go to auto parts store and purchase a block heater. this has rubber expandable gasket. May even find that type of frost plug. In Canada, another block heater is the answer. Cheers.
