To know the exact engine size in *your* specific 1999 Dodge Ram Van 1500, you'll need to check:
* The vehicle's title or registration: This document often lists the engine size.
* The sticker on the driver's side doorjamb: This sticker usually contains information about the vehicle's specifications, including the engine.
* The engine bay itself: The engine's displacement is usually stamped on a part of the engine block.
