In the middle of swapping a 4.0 in a 2000 Jeep Cherokee Sport. What a pian in the rump. Granted I am used to a lift and air etc. doing this one at home. It took the better part of three days to get the old one out. Which brain dead engineers dumb idea was it to use ten diferent size bolts and nuts on everything and then toss in two 12 mm torx headed bolts at the top of the bell housing right were you can hardly get to them. The 2 coverter / resinators in the head pipe and inch below the head pipe bolts is handy too. The clips that bend so the head pipe bolts just spin and spin around work well too. Had to pull the intake just so I could get to them with the torch. Had to unbolt the shift cable braket to get the bottom crank sensor bolt, and I still needed to be a contortionist. Got the top one from up top with a ratchet wrench also could hardly reach it. Anyone of Chryslers engineers from that era need a slap in the head. I could have had two small block or big block Chevys out, back in a Chevy truck and running by now!
Anyway any tips on putting the new engine in would be awsome, thanks in advance, and for reading my vent! Harold.

Are you swapping a 4.0 for another 4.0 or are you taking out a 2.5 and putting in a 4.0?

Sounds like a fun job, Maybe it would have been easier to pull engine and trans together ?
After reading your rant I can tell you this, If I ever have to pull my 4.0 that small block & turbo 350 sitting in my shop floor is going in. :smokin:

Swapping a 4.0 for a 4.0. Got it set in and bolted to the trans, & motor mounts in last night. It went it tough but some fanageling, brute force, & ignorance got it. Just have to assemble, & hook everything up now. No reason to pull the trans. plus that would mean a whole bunch more poorly enginered stuff to take apart and put back together. Plus the motor barley fits up out of the hood hole I can't imagine trying to get the trans out too.

Well I finished it up today. Started it up noticed a bit of trans fluid leaking from upper trans cooler line. Tightened it some more, noticed it wasn't chahrging. Investigated the alt. and found I had forgoten to plug the wire in to the back of it. Took it for a ride, seems to go good. Runs allot better than the old motor ever did even before the problems leading up to its demise.
