Difference in 2001 and up 4.0L engines?
Just being curious, I checked out LKQ for used engines for my 2003 4WD 4.0L Ranger. What was weird is they had 4.0L marked as:
2001 - 2003
2005 - 2006
2007 - 2011
I'm wondering, does anyone have any idea why they'd do this? Perhaps ECU was different for those year ranges?
I was always thinking, if I couldn't be in a position to do a VW TDI swap, that I'd find the lowest mileage newest year 4.0L I could find, put in new OE tensioners and spark plugs, swap accessories over (and I was under impression even a 2011 4.0L block would work for even a 2001 4.0L Ranger), and be off and running.
Is this not the case?
