I JUST PICKED UP A 02 JEEP LIBERTY 3.7 V6 AND NEEDS A MOTOR WHEN I LOOK THEM UP IT SHOWS THAT 02 AND 03 MATCH YOU WHAT IS THE DIFFERENCE BETWEEN THOSE YEARS AND THE 05 AND 06?
the tone ring is removable and can be changed to the 02.the cam gear can also.it's not fun,i'm one of those people that made it work.i put a 05 in a 02 and learned the hard way.02-3 has the first generation computer and 04 and up is 2nd gen. The tone ring on the crank (not removable), cam gear/reluctor, block, heads etc. A whole lot of differences. Our customers have ordered the engine for the wrong year vehicle and got it installed and had to pull it and pay restocking and get the correct engine. We sell them like crazy and keep them in stock.
