2006 Ford Explorer 4.0 L Firing Order – It’s essential to know which lender (or cylinder head) is # 1 to help determine a starting place for firing order or maybe to exchange the appropriate portion, like an Oxygen indicator, gas injector or ignition coil.
Before all of that was required to determine which lender or cylinder go is # 1 was to find out which cylinder mind is placed the farthest forwards. One that is the most forwards (closest to the front side of the engine) is the top cylinder and therefore side is bank a single.
But a majority of motors nowadays have cylinder heads that are located uniformly, that makes it harder to determine which is bank # 1 and which happens to be lender number two. A number of popular good reasons we have to know this, as an example is usually to determine Oxygen sensor to change when you would like B1 S1 (Lender One particular Sensor A single), or if perhaps you’re trying to identify an ignition coil to examine for any P0301 (#1 cylinder misfire captured) misfire code.
