2004 Ford Explorer 4.6 Firing Order – It’s essential to know which bank (or cylinder Top) is primary to aid establish a starting place for firing order or just to switch the right part, as an Oxygen sensing unit, gas injector or ignition coil.
In the past everything that was essential to find out which banking institution or cylinder head is number one was to see which cylinder go is placed the farthest ahead. The one that is easily the most frontward (nearest the leading from the engine) is the top cylinder and that area is lender 1.
However, many engines these days have cylinder heads that happen to be placed consistently, which makes it more difficult to determine which is bank number 1 and which is banking institution number two. A number of common good reasons we should know this, for instance would be to determine Oxygen sensing unit to change when you would like B1 S1 (Financial institution A single Detector A single), or maybe if you’re seeking to track down an ignition coil to inspect for the P0301 (#1 cylinder misfire documented) misfire code.
