Where are the spark plugs on a 2002 Ford Ranger XLT?

The spark plugs on a 2002 Ford Ranger XLT are located on the top of the engine, under the valve covers. Because there are different engines that could be in a 2002 Ranger XLT (a 2.3L, a 2.5L, a 3.0L, or even a 4.0L V6), the exact placement will vary slightly. They're generally accessible, but you'll likely need to remove some components for better access.

To be certain and avoid damaging anything, you should consult a repair manual specific to your vehicle's engine. A Haynes or Chilton manual, or an online resource like a digital version of a repair manual (many are available on sites like Amazon), will provide detailed diagrams and instructions. These manuals will show the location precisely, and also give you the correct spark plug type to use.
