Re: 2002 Jeep Liberty 3.7 V6 Engine compatabiity
The 02 & 03 Liberty's are interchangeable . In 04 Jeep switched to a different computer system . To use your engine in a newer than 03 you would need to swap reluctor rings on the crankshaft & tone ring on the camshaft .
Also might need to swap intake manifold & a few external parts .
