Swapping a 5.7L V8 Hemi from a RAM 1500 into a 2010 Jeep Liberty with a 3.6L V6

- We replaced the original 3.6L V6 with a powerful 5.7L V8 Hemi sourced from a RAM 1500. Disconnecting and removing the exhaust system, radiator, and other accessories connected to the engine, as well as detaching the wiring harness, throttle cables, and fuel line, were the easy parts.
We had to ensure the engine mounts aligned with the Jeep's frame and check compatibility between the Hemi and the Jeep's transmission. For that to happen, it had to be the same year donor and recipient. Though some modifications in the motor mount were necessary, considering we were putting in a bigger motor, so space is tight.
Integrating the Hemi's wiring harness into the Jeep's electrical system was another intricate puzzle, requiring adaptation or modification of connectors as needed to establish proper connections.
That's just half of the work. The cooling system was a challenge. We had to install a new, big radiator that could effectively cool the increased power of the Hemi engine. We also modified and fabricated the entire exhaust system to achieve proper alignment and secure connections, but that's for another video.
We hope you find this helpful and keep track of our future videos to stay updated.

Please post some more video's about this, I would like to do this to my 2012 eventually. Awesome job
Thank you for your comment! We'll be posting more of this in the future, we're still working on it. If you have any question or suggestion don't hesitate to contact us!
@@meautoaccessories You guys are doing a great job, how much more weight is the 5.7 compared to the 3.7?
@@jeremywahl8544 Oh well, we didn't weigh them, but I know it is a lot more! Either way, the suspension will handle it after the system upgrade we did (Bilstein Struts and Old Man Springs)
@@meautoaccessories I have a 2.5" Skyjacker lift on mine. I would have to get ahold of them to find out if they are upgraded springs, I know they are longer than the original.
O man I want to do my 2009.
Go for it, man. It definitely can be done.
Need to retire mine as a daily she has 250k+ on her and get a new daily driver/work 4×4 first.
Is it running and driving already? Any plans to document it once is completed? I wonder how is the front diff going to manage the new torque
Good question 😂
Customer knows that! Even the rear diff. We are not sure how's gonna hold it, but once it is completed, we will post an update.
What's the estimate on this job???
Just labor rounds 10k. The cost of parts varies based on their accessibility. It's a lot of hard work, but totally worth it!
Thanks for the info! I can't wait to either do it myself or send it to you lol. Just seen the video of it backing out of his driveway sounds amazing. You all did a great job!.
@@FlySavageFPV Feel free to count on us to do the job! It's rewarding hearing that freaking sound after all the hard work!
Will the gauges work?
Yes, of course, everything is working as in factory
5.7 and 3.7 uses the same pcm.
They use identical PCM units in both the 5.7L and 3.6L engines, but their programming differs.
@@meautoaccessories they run on the same program it’s just flashed over to a hemi file the program doesn’t change it also looks like you’re not using an original pcm . Because the engine plug on the original harness is exactly the same. You also left out you welded hemi brackets to the subframe.
@msengineeringdavid3148 they're all the same plugs, but still, you need to have the computer to program it and change the file. Autel or SnapOn scanners don't do that. I used a pre-owned 2010 RAM PCM instead to avoid programming, which is plug-n-play, just need to change the VIN number
