The 2003 Ford Escape was equipped with two different engines; a 2.0-liter four-cylinder and a 3.0-liter V-6. The four-cylinder engine was produced with a single ignition coil pack that provides the spark for all four cylinders. The 3.0-liter V-6 uses a coil-over ignition system, that has individual ignition coils over each spark plug. The coil-over ignition wires and coils can be removed individually with minimal effort. The No. 3 cylinder on the 2003 Escape 3.0-liter engine is on the rearward driver's side of the engine.

Remove the mounting screw from the ignition coil, using your 1/4-inch-drive ratchet and socket. Use an extension on the ratchet for easier access, if needed. Remove the ignition coil from the engine, pulling it straight upward by hand.
Install a new ignition coil onto cylinder 3, and push it straight downward over the spark plug. Install the hold-down screw and tighten it to 89 inch-pounds, using an inch-pounds torque wrench and socket.
