Question About Cylinder 4 2005 Durango 3.7
3 Answers
It's the second one from the front on the passenger side. #1 is left front (as you're sitting in the car), #2 is right front, and so on. This is NOT the firing order on the disrtibutor cap wires! I believe that is 1-8-4-3-6-5-7-2
The firing order I listed is for a V8 (I know that one by heart, don't ask why LOL). For the V6 it's different, but #4 is still second from the front (or middle) on the right.
It would be the fourth plug back from the front. ALL inline motors count the plugs from the front. Note this not the firing order for the motor just line up of plug #'s. The firing order listed for the V8 is a small block chevy order, please keep in mind that a FIRING ORDER is specific to a motor not a car. Example is the 302 FORD which with the change of the cam it will change the firing order, ie the millions Ford spent on getting the sound from the 5.0
