The 4.0 in my 2000 is finally dead and I'm swapping in the one from a 94. Any tips/tricks for removing/installing the motor? Anything a should take into special concideration? Thanks in advance guys!

 

I strongly recommend investing in a year specific FSM. They can be found on eBay and they're well worth the money.

 

How did you kill the engine? How many miles?

 

to make it easy for you remove the Hood... it will get in your way.... When removing and installing the engine hope this helps...

 

Remove the front grill assembly as well it will help alot.

 

take before pics of both motors installed if possible lots of them where all the wiring and sensors go vacuum lines etc. label and tag all the wires. do the same with all the bolts you remove(ziploc bags and label them) good luck

and google till youre eyes hurt

^^^ you bet! The fasteners, vacuum lines, etc all start looking the same once they've been removed, lol. There's nothing better than good pictures of where things are supposed to go.

 

Hood and front end removal are unnecessary steps. Never done either one and had no issues.

Be aware that teh top two bell housing toengine bolts are E12 heads. Loosen/remove them before any others.

 

Yea I have never removed the from end but the engine hoist hit the bottom of the hood soo that's why I suggested it

 

School me...

Why are you goining to install a 1994 4.0 in place of your 2000 4.0?

 

Because my motor had a cracked head which killed the bearings and made it knock like the police on the door of a high school party. 15 minutes after she started knocking a guy heard it and told me he would sell me one out of a 94 for $300. I think that's a good price. Also on my way home from work last night it gave out so I need her back on the road ASAP

 

Oh and I'm doing it with my buddy at his house and his old lady has a 2000 xj as well so hopefully that will give me good refrance

 

There may be too many differences between the '94 4.0 and the '00 4.0 for you to cope with, such as intake/exhaust manifold compatibility between the two cylinder heads and the lack of a coil rail attachment on the '94 head.

Consult with cruiser54, and others, on any/all problems you'll run into.

 

I plan on swapping the heads. The head on my current motor is off an 04 grand so im hoping all I need is to swap heads and swap the distributor for the cam sensor but trust me if I have any problems I'm coming on here. So many good recourses
