To be certain:
* Consult your owner's manual: The best resource is your owner's manual. It should have a diagram showing the location of major components.
* Use a repair manual: A Chilton's or Haynes repair manual specific to your 1995 Ford F-250 will have detailed diagrams and instructions.
* Look online: Searching for "1995 Ford F-250 starter location [engine size]" (replace [engine size] with your engine's displacement, e.g., 7.3L, 5.8L) on sites like YouTube might yield videos showing its location.
Keep in mind working on a vehicle's electrical system can be dangerous. If you're not comfortable working on cars, it's best to take it to a mechanic.
