To find the correct routing for *your* 2002 Ford 4.6L engine, you need to:
1. Check your owner's manual: This is the best source. The manual will have a diagram specific to your vehicle's configuration.
2. Look under the hood: The belt routing is often printed on a sticker located under the hood, sometimes near the radiator or on the engine cover.
3. Use a reliable online resource: Websites like Ford's official parts website or reputable automotive repair sites might have diagrams based on vehicle identification number (VIN). Be sure to input your VIN for accurate results.
4. Consult a repair manual: A Haynes or Chilton repair manual for your specific vehicle will also contain a detailed diagram.
Without knowing the exact make and model of your 2002 Ford vehicle, providing a specific routing diagram is impossible and could lead to incorrect installation. Improper belt routing can damage your engine's components. Always refer to a reliable source specific to your car.
