Ford 3.9 V6 Firing Order – It’s essential to know which lender (or cylinder Top) is number one to help you determine a starting place for firing order or maybe to change the appropriate aspect, like an Oxygen sensor, gas injector or ignition coil.
In past times everything was needed to find out which financial institution or cylinder head is number one was to see which cylinder head is located the farthest forward. The one which is the most frontward (closest to the top in the engine) is the top cylinder and this area is bank a single.
But a majority of motors today have cylinder heads which can be located uniformly, rendering it tougher to find out which is lender # 1 and which happens to be banking institution number 2. A couple of common reasons we should know this, as an example is always to figure out Oxygen sensor to exchange when you are looking for B1 S1 (Financial institution One particular Indicator 1), or maybe you’re seeking to track down an ignition coil to examine for the P0301 (#1 cylinder misfire documented) misfire code.
