Cleveland can claim partial credit as "Cod"'s birthplace, since the submarine's five massive diesel engines were built at the General Motors Cleveland Diesel Plant on Cleveland's west side. "Cod" acquired two General Motors Model 248 engines that had originally been used aboard another World War II submarine, . The two V16 1,600 HP diesel engines were originally built in Cleveland, Ohio, the last in 1943, out of the General Motors Cleveland Diesel Plant. The engines were used for parts for the restoration of "Cod" engines. Four out of the five main engines on the "Cod" are in running and working order, and are fired up on special events through out the year. In 2013 the Cleveland office of PetroLiance helped the "Cod" get 500 gallons of fresh oil to operate her newly restored engines. "We are proud to help "Cod" get her engines running again", said PetroLiance regional VP Jim McClellan. It amounts to about a $10,000 donation, said Paul Farace, president of the "Cod" memorial.
