I just bought a 2001 Jeep cherokee 4.0 with a bad engine. I found a engine out of a 1998 with super low miles, i was hoping somebody would be able to tell me if it would fit in my 2001 cherokee. Thanks for any help.
All 4.0l are basically the same. However, I haven't worked with the 99 and newer 1s yet to know for sure. I know there will be alot of differences with the sensors and such. The block and head are different casting numbers, but that doesn't always disqualify it. I've heard that alot of guys like using the older heads on the newer motors for increased airflow.
