Q: How to remove and install ignition coils on Ford Edge?
A: Disconnect the negative battery terminal. For 2015 and later four-cylinder models, remove the engine cover by freeing the four grommets. For 2014 and earlier models, remove the air filter outlet duct and EVAP canister purge valve. For 2.7L V6 engines, remove the engine cover and EVAP hoses. For the rear coils, remove the right air filter housing outlet pipe. For 3.5L and 3.6L engines, remove the engine cover and PCV hose. For rear coils, remove the upper intake manifold. Disconnect the ignition coil's electrical connector, remove its fasteners, and pull it off the spark plug. Reverse these steps for installation.
