Jeep 4.0

An 4 cubic liter inline six engine produced by Jeep from 1986-2006. Used in XJ Cherokees, YJ and TJ Wranglers and ZJ and WJ Grand Cherokees. Well known for being one of the toughest and most dependable engines ever produced, it's not uncommon to see these motors running past 300,000 miles.

"You really have to try hard to kill a Jeep 4.0 , I drove my XJ into a pond and it stalled out. After I got it out and changed the oil, it ran fine like nothing even happened!"
