2002 Ford Explorer Firing Order 4.0 – It’s crucial that you know which bank (or cylinder Top) is number 1 to assist figure out a beginning point for firing order or just to change the appropriate component, just like an Oxygen detector, gasoline injector or ignition coil.
In past times all of that was needed to find out which financial institution or cylinder go is number one was to determine which cylinder go is positioned the farthest forward. The one that is the most frontward (closest to the front of your engine) is the number one cylinder and that area is lender 1.
But a majority of engines right now have cylinder heads that happen to be placed consistently, that makes it more challenging to find out which is lender # 1 and that is bank number 2. A number of typical reasons we need to know this, for example would be to figure out Oxygen detector to replace when you are searching for B1 S1 (Banking institution One Indicator A single), or maybe you’re seeking to locate an ignition coil to examine for any P0301 (#1 cylinder misfire documented) misfire code.
