To replace the ignition coil on a 2003 Ford Escape, first, disconnect the negative battery terminal to ensure safety. Then, remove the engine cover if necessary, and locate the ignition coils on the engine. Carefully disconnect the electrical connector from the coil, remove the bolt securing the coil, and then pull the coil out. Install the new coil by reversing the process, ensuring it is properly seated and the connector is secure before reconnecting the battery.
