Where is the starter for a 1991 Ford F-250?

On a 1991 Ford F-250, the starter is typically located on the passenger side of the engine block, near the bellhousing (where the transmission connects to the engine). However, the exact location can vary slightly depending on the engine (e.g., a 4.9L inline-6 vs. a 7.3L diesel). It's usually fairly accessible, but you may need to remove some components like the heat shield to get a good look.
