2000 Ford Explorer 4.0 L Firing Order – It’s important to know which bank (or cylinder Top) is # 1 to help decide a starting place for firing order or perhaps to change the right portion, like an Oxygen indicator, gas injector or ignition coil.
In the past everything was essential to find out which financial institution or cylinder go is number one was to determine what cylinder mind is located the farthest frontward. One which is regarded as the frontward (nearest to the front side from the engine) is the main cylinder and this area is financial institution one.
But some engines right now have cylinder heads that happen to be located uniformly, rendering it more difficult to find out which is lender # 1 and which is bank second. A few common good reasons we should know this, for example is to determine Oxygen sensing unit to switch when you are interested in B1 S1 (Bank A single Sensor A single), or if perhaps you’re seeking to locate an ignition coil to examine for a P0301 (#1 cylinder misfire documented) misfire code.
