Engine swap
Hey guys I have 1998 Cherokee 4.0L, the engine is bad and I found another one to swap, I had a question on whether or not I would be able to swap a 1998 grand Cherokee 4.0L engine without any issues, I found out the trans aren’t the same, I have an AW4 and ZJs have something different, will I be able to bolt that 4.0L to my AW4 or will this engine not work?

So zj and xj should be the same. To be safe I'd keep all the sensors and accessories from the motor you pull out of your jeep

I planned on swapping the computer and all sensors, just putting my a/c compressor from old engine on this one that’s it , rest is being changed.

I don't know if the computer from my XJ will work, the engine I have in the jeep currently is a 2000 4.0L so it has the ignition coils instead of distributor cap. Will the computer work for a distributor?

Okay thanks, will my a/c compressor be an issue If I swap that over? I know the one I’m buying the a/c don’t work but mine is ice cold and I’d like that for the summer time haha.
