2010 Ford Expedition 5.4 Firing Order – It’s essential to know which lender (or cylinder head) is # 1 to help determine a starting point for firing order or perhaps to exchange the appropriate aspect, as an Oxygen sensor, gasoline injector or ignition coil.

Previously all of that was necessary to determine which financial institution or cylinder brain is # 1 was to determine which cylinder mind is positioned the farthest forward. One which is regarded as the forwards (nearest the front from the engine) is the number one cylinder which side is lender one particular.
