Nice work,

 

A few more pictures. I know I make it sound easy and to me it was pretty straight forward. Now I do this for a living and have a nice big shop with air tools so it went faster. I think we pulled it into the shop around 10:30-11am and drove it out of the shop around 4:30-5pm.

If anyone has any questions I will be more than glad to answer them.

I wonder if they use different cams? keep the photos coming and good job.

 

They have the same cam. All the internal parts are the same. I have a buddy that works at a Jeep dealership and he looked everything up on the engines.

 

These are the aluminum lines that will need to be swapped that go to the heater core. Also if you have a manual tranny do yourself a favor and replaced the clutch assembly unlike we did. My buddy was short on cash so we didn’t do it. But 3 weeks later we replaced it in a Pizza Hut parking lot. That was not fun at all.

 

You're a good friend. Nice job - thanks for sharing.

 

definitely subded. Thank you!

 

that was very cool. way outside anything I'd ever attempt, but super cool

 

Nice work!
I presume all the electronics dove-tailed in with the sensors and no codes!

 

Yes everything was plug and play. Only code was O2 sensor but that was from his d engine burning 5 quarts of oil every 700 miles. Also Jeep stealership told him that was normal. Yeah crazy Right?

 

Thanks for sharing.

 

Nice work!

I wonder if a 3.6 out of a RWD LX car would be easier to swap

It's nice work and all but... ....the TJ guys already tease us about having a minivan engine...

You near GA? I'll need a clutch eventually.

Well I do own a TJ lol. I am in Northern VA. If I was closer I would help you out.

 

Don’t want to steal the thread but does anyone know if I can do the same with the 3.8 into my 07 with a mini van engine

 

There was a thread awhile back on this.. apparently the 3.8L block is a different casting. The motor mount ears on the block are different so the 3.8L van motor will not mount up in the Jeep.

Thanks and good to know.

 

So here we go. As most of you know a 3.6 for a Wrangler isn’t cheap. So my buddy had a cylinder 2 failure in his 2012 Wrangler. Got on the ole web to find an engine. After doing some digging I found out that a 3.6 Caravan long block is the same. I went with a 2015 model because it was after the left head rework. So I found one from LKQ with 17K for like $1200 plus freight for $200 more so $1400 total.

My first thought was, what were the signs and symptoms of your friends #2 cylinder failure? Was it a code on the CEL, a obvious miss, a miss and or blowing blue smoke out the exhaust. My luck would be that I change everything over to the new engine and something I swapped over was the cause of the failure, like an injector or igniter. How did you do the final analysts indicating it was long block replacement time?

 

Sorry, I read further and #19 (I think) answered my question. I missed that one the first time. By the way, excellent write up and that WAS a great deal for an engine with 17K on it.

 

He took it to the dealership to have it checked out a second time and I went with him. After I argued with the head mechanic and service manager for 30 minutes and had a service advisory on the left head issue they dove deeper into the issue. But because he wasn’t the original owner they couldn’t replace his engine under warranty.

The left head issue is as follows.

Metal shavings are not cleaned out of the head properly after the machining process and and can possibly get in the cylinders causing premature engine failure.

When he bought the Jeep it was using oil and progressively got worse. So whoever had it before him knew it had an oil consumption issue but just traded it in.

 

this is why I changed out the oil after the first 1000 miles....

 

Also correction on the used engine mileage it only had 12000 miles on it.

 

I think the 3 hours clutch change at pizza hut is more amazing than the quick engine swap. I think i spent about 2 days changing mine clutch last time.

 

That's a great write up. I've done a swap of an Explorer 302 into the place of a fox body Mustang 302 and it sounds very similar, except for the fact that anyone making that change will swap the cam for an alphabet cam and there's some finagling with the throttle cable and tps to make it work.

Nothing like some of the Subaru guys have to go through, taking one cam gear from one engine and swapping it to the other, but not the other 3 kind of stuff.

Also impressed on a 3 hour clutch change in a parking lot. Did a Mustang one in 6 hours in my own garage with air tools.......

Got it up to the shop. Engine pull is pretty straight forwad. Hardest part is the 2 top bell housing bolts but 3 12” extensions and a wobble socket got the job done. Engine was out on the floor in less than an hour.

After comparing both engines and what needed to be swapped out we started pulling all the parts off. So what I noticed right off the bat was the sump is different. This is a two piece pan. The bottom is steel while the top half is aluminum. Both have to be changed out. Also the oil pump pickup is needs to swapped out. Next is the water pump and timing cover have to swapped out. Reason being is the Caravan is sideways in the van so none of the idlers and pulleys will mount up. Got all that done.

Next is the plumbing that run from the engine to your heater core will need to swapped out. After that the engine harness needs to swapped out. This is really easy as all the sensors are the same. The difference is the plug on the Jeep is different from the Caravan. Also the top half of the intake is different so it needs to swapped out. All that is left now is putting on your old engine mounts.

You do not have to thread any holes or do any drilling at all. Everything swaps right over to this block. Oh you will also need to change out your flywheel. It only goes on one way. The bolt pattern is a one way deal so you will need to spin the flywheel around until the bolts line up. It can be a real pain in the arse but just be patient.

I recently read your post and have since done the same exact engine swap, except mine was a 2016 grand caravan motor. I drove it 20-30 miles home with no issues and it wasn't until I got to the car wash and parked in the self wash bay until a CEL came on, ill be checking the code later today. Did you have any weird issues regarding electronics? sensors, cam phasers, etc.

 

Welcome to the Forum, from Cave Creek AZ.

 

I have a buddy who hydrolocked a 3.6 when the thing still had paper plates. Somehow his insurance paid for it. $10000 for a brand new 3.6.

I had no idea that used ones went for this much, I'm getting ready to do a 5.3/TH350/NP205 swap, my 3.6 with 36,000 on it should help recoup some of those costs.

 

Is there any reason a 3.6l out of a truck or even out of a 14 plus would not work in a 2013 jku?

 

Not really. You need to swap the upper intake and the timing cover and belt driven accessories.

 

The truck version. The 14+ should have the same accessories as your 13. Be aware of the oil filter difference between those 2 years.

 

Yeah the only difference I knew about with the 14+ was the oil cooler and filter assembly, but all the used parts dealers keep telling me they will not work, but those are positive changes.Thank you.
