* Your Owner's Manual: This is the first place to check. The manual should have a diagram, though it might be simplified.
* Online Repair Manuals: Sites like Chilton, AllDataDIY, and Mitchell 1 offer online repair manuals (often subscription-based) with detailed diagrams and instructions. These are usually more comprehensive than the owner's manual.
* Online Forums: Search on forums dedicated to Dodge Stratus or Chrysler vehicles (e.g., DodgeForum.com). Someone may have posted a diagram or photo of their engine bay with the belt routing clearly visible.
* Auto Parts Store Websites: Websites like AutoZone, Advance Auto Parts, and Napa Auto Parts often have online parts catalogs. While they might not show a dedicated routing diagram, the diagrams associated with the serpentine belt itself sometimes give a visual clue. Searching for "serpentine belt 2004 Dodge Stratus 2.4L" will bring up relevant parts.
* YouTube: Search for "2004 Dodge Stratus 2.4L serpentine belt replacement" on YouTube. Many videos showing the replacement process will inherently show the belt routing.
Important Note: When replacing a serpentine belt, it's crucial to use the correct diagram. Incorrect routing can lead to engine damage. If you're unsure, consult a professional mechanic.
