1999 Jeep Cherokee XJ 4.0 Engine and Transmission Swap Guide 

This is great as a reference video for all of the connector/bolt/bracket locations. I pulled my engine out for a rebuild 8 months ago and am finally going back together and I keep coming back to this video to check where little things go. Thanks for taking the time to document all of this, might seem like overkill to some but it's definitely a ton of useful info

The fact that you guys did this in 36 minutes is impressive. Bravo!

I think it's great that these young men actually took on such a job. Great work men!

I've watched many different videos over the years from professional mechanic shops showing how to do certain jobs and this is the best tutorial video on a project I've seen to date. Good job!

Super impressed. You guys did an awesome job. There's no better feeling than when it fires up for the first time and you know all that work paid off.

you guys did a great job . im impressed you don't see to many young guys doing their own work . you can do as many upgrades as you want . good job

One of the best ways to learn is by DOING. They took action and learned along the way.

Excellent vid guys. Thanks so much for documenting the whole process. My pride and joy, '98 XJ, has died - overheated and engine blew, and i was about to scrape the whole car. You'all are an inspiration. Cheers.

I watch this video every time I take something off my Jeep. Thank you so much.

Great to see other kids that are around my age (17ish) wrenching on them XJs. Especially that u guys don’t know much shows just how easy they are to work on (minus the damn siezed/rusty bolts)

35:00 that feeling when you get it started for the first time. love this

270k on my 96 zj and finally the engine has to be swapped. You three are brave for taking on such a complicated project but kudos to you for following through and completing the job. I'm sure victory was sweet once she turned over!

It's a pretty long video so here are some time stamps for the best/funniest parts. 3:25 Spilling coolant everywhere 30:50 Trans removal 33:30 Engine Removal 35:00 Some more issues 35:50 First start

I have to hand it to ya guys. Great work, not a single curse word on this video. This country needs more young men like you guys. Absolutely wonderful video. Now if I could just get my son to help me out doing my motor.

Great video...you guys rock Dedicated to wrenching ... one day when your old your gonna remember that day it fired up after all the crap you went thru ... It reminds me of my youth, pulling a motor with my friends ... Been wrenching for 45 years .. I’m 58 now and gonna pull out my 4.0 outta my 2000 Cherokee This video will help a lot .. thanks guys Keep the videos coming ....

Blew up my 5 Speed XJ having a bit too much fun on a trail, here i am.

Inspiring. Been putting off pulling engine from old 2000 xj to swap to new/old 2000 xj. Thanks for the engine pull video 👍👍

You guys have taught me so much more than any other person or video

Nice job guys. Seriously, this is awesome.

Good job guys, way to team effort the project. It’s a lot of work but the mission was accomplished! Did it myself on a 88 runs great 👍. Definitely worth the effort, the jeep is gonna last a long time.

Outstanding Guy's, you brought back good memories of myself back in the day...!!! We are all super proud of you-all (( team-work )) for sure & a job well done ... This is how you Learn Things,, get in there and just do it ------ No matter what happens you learn (( try & learn from others mastakes )) ,,, Good Job Guy's.....!!!!

There's no "pipes" on a vehicle. Hoses and lines. I commend you young men. This is awesome!!

Good learning experience and teamwork! Very nice, i just subscribed.

I love the excitement on the first start

I’m just now seeing this video. It’s awesome!!! Thank you so much for taking the time to shoot this video. It can be a teal pain in the butt to get work done and also video everything. So thank you guys!!!! Just awesome! Where can I send you a few bucks? Nothing says thank you like $$$!!!👊👍

This is why jeeps are amazing

This video brings me so much joy, I am 40yrs old and have just started working on vehicles. I am a certified youtube mechanic and seeing you guys knock this out in the driveway, not only give me hope for me. but hope for our future generation.

хорошее состояние!Я из России и у меня XJ 92 4.0 сделал сам капитальный ремонт двигателя. Вы молодцы

Excellent video

Awesome work fellas!

Great job guys.

Good work guys....looks good

You did a good job, guys!

Excellent video, Thank you

Great job. Thanks for the video.

That is one clean xj.

Amazing job

Well done and thankyou for posting

You guys are awesome

Good job boys!!

You have no idea how lucky you are for having friends to help you out. Great video and great work. One question is why are changing the original engine? Are replacing it with a bigger block? Thanks

nice job awesome video

nice video very detailed

You guys rock!!! Thanks so much.

Awesome bro !!

Well done fellas!

good work guys. thanks.

I have a 99 grand cherokee 2wd with a good 4.0 I6 engine and another very nice grand cherokee 4x4 with a blown v8 engine was gonna swap the good engine for the blown engine my question is whether the automatic transmissions are the same. Or do I have to swap them as well ? Any help appreciated.

Great video. Nice to see such young lads taking on a project this big. How did you fix the timing issue?

Good work!!!

Good job mate

Nice job

Good job guys

Feels good dont it boys when you accomplish something like that. Nice job

Well done fellas

YES, YES👍👍 S O L I D . GREETINGS FROM TOLUCA MEXICO.

good job!

nice xj. I had a black 98 that looked similar to that one. 5.5 inches. stock steel wheels and 31s. I had KC lights on it too. what's ironic is I did a motor and tcase swap on it too lol

Congrats on the job..Great video, learned alot. One suggestion though, when talking about buying the torx socket set...its like $20. You are doing a couple thousand dollar project, if u need a $20 tool, just buy it, not worth driving around to save $2 on a $2000 job.

12 minutes in and I already forgot how to put together most of the things 🤣 I'd have an anxiety attavk

Ahhh, thank you. I'll be doing this in a few weeks for the first time. Wish I could give the video 20 more likes.

What are you swaping it to the 4.0 is all you need in the trail or off road. I port and polish head new at performance off road heads. full exhaust. Cheap banks gen1 T/4 turbo kit making 344 horsepower 450 torque low boost all low end power 2 years no problem. 230k miles on stock block

What size 12 point socket did you use to remove the head ?

Fun fact...replace the e12 socket head bolts with 3/8-16 x 1.75 long flange bolt. Then use a regular socket or wrench 🔧 🤔 simple upgrade for the next time u gotta pull that 4.0

Awesome guys

great video guys, going to be pulling a 4.0 from a XJ this summer to put in my TJ upgrading my 2.5L loll

yo just a heads up I use a Home depot Mud tub its big black rectangular shape catches alot of stuff so you dont get it on moms driveway or on her garage floor!!

What oil did you use to break the new engine in? Did you just use regular oil or did you use a break in oil?

Man this is so lit

I like how they call the hoses "pipes".

awesome job! about to hit 200k on my xj so I'm expecting to do this soon👌

How did u removed the ac condenser lines??

My question is where did you rent the engine hoist?

Where did you rent the engine hoist? I'm away at college trying to find a way to pull my motor in the parking lot because I blew it up

Blowing a bulletproof engine sounds hard to do. How did it happen??

Nice job guys. What size lift are you guys running on this XJ? Any adjustments were made for that during/ after the swap? Pure curiosity. I'm pulling a 4.0 right now from a 98' XJ to put in my 94' YJ 2.5L. and the video giving me great help. The 2000 XJ 4.0 daily driver I run is ready for a lift and that's why I'm asking. I'm just glad I don't have to pull my XJ motor from the 00' to learn how to pull the 4.0 I'm using for the YJ rebuild. Both motors are pretty close with respect to removal. Good Effort. It's good to have friends.... (I'm screwed. Sons aren't old enough to for engine swaps).

Where did you get the rebuilt engine?

What kind of engine did you take out of it and what kind of engine did you put in it

Do you have to take the transmission loose?

Where’s the transmission bolt section gotta get my trans swapped

What was the total time you guys did this in?

Where do you rent them hoist at?

where did u get your motor?

How did you guys disconnect the AC lines? was there a tool that you push into those donut connectors? or just yank em off I'm trying to take the ones off my xj donor jeep but no luck yet.

I’m hoping to pull mine this weekend. I’ve got no help so it’s just me and my tools. I’ll also be rebuilding it myself. Never did it before but youtube videos have been great although I can’t stand youtube ads any more. I don’t know how many more Michael Bloomberg ads I can take before shooting my AR at big empty big gulp cups I just drank.

A lot of people don’t know there is a drain plug in the radiator it’s on the bottom side to the left (facing the jeep)

Soo i am doing this on my 98', and need to know if its possible to remove the motor, trans, and T case as a whole. And also, is it necessary to remove the intake and header for the removal?

Why did y'all separate the engine and transmission instead of pulling the entire power train out in one unit?????

That's cool

What can I do if my e12 bolts stripped? I’m ready to just take the motor out but these bolts are ruining my life
