Where is the ignition coil on 2003 Ford Expedition?

The ignition coil on a 2003 Ford Expedition is typically located on top of the engine, near the spark plugs. However, there isn't one single coil; the 2003 Expedition uses multiple coil packs, one for each cylinder (or sometimes grouped for several cylinders). These are usually easily identifiable as black rectangular boxes with wiring harness connectors.

To pinpoint the exact location, you'll need to:

1. Consult your owner's manual: This is the best resource as the location can vary slightly depending on engine type (4.6L, 5.4L).

2. Look at a diagram: Online searches for "2003 Ford Expedition ignition coil location diagram" will reveal images showing their placement.

3. Visually inspect the engine: Look for the black rectangular boxes near the spark plug wires. They're usually relatively accessible on top of the engine.

Remember to be cautious when inspecting the engine compartment. The engine may still be hot after running, and there are many moving parts.
