How do you take the oil pan from 94 dogge van?

As early as 1899, Clyde J. Coleman applied for U.S. Patent 745,157 for an electric automobile self-starter - inventing one that actually worked waited until 1911 when Charles F. Kettering of Dayton Electric Laboratories (DELCO) invented and filed for U.S. Patent 1,150,523 for the first useful electric starter. The starters were first installed by Cadillac on production models in 1912. These starters also worked as generators once the engine was running, a concept that is now being revived in hybrid vehicles. By 1920, most manufacturers included self-starters.
