Putting a 2002 Liberty 3.7 V6 into a 07 WK 3.7 V6

Hi everyone,

I am a newbie here and I just got a blown motor 2007 WK 3.7. Currently, I need to find an engine to replace it. I found a good deal from 2002 Liberty 3.7 V6, which has a blown gasket that I am going to rebuild.

May I know what are the precautions I should consider when putting an older engine like the 02 Liberty into a newer vehicle like WK? Is there any difference in mechanical parts (like sprocket or lifter) between these 2 engines I mentioned above? Do I have to reprogram the PCM upon using this 02 engine?

On the other hand, I would like to expand my search on which model in the Dodge/Jeep products are compatible with the 3.7 in this WK.

I apologize for the long questions and I really appreciate everyone's input as this is my first engine rebuilt.
 

Check Novak website.

Use the PCM that came with the engine you use.

There is likely more but that’s the basics.
