Great video. I’m starting the re-assembly of my Jeep and it is very helpful to see the job done by someone who knows the job well. Reassuring to know that I’m on the right track.
It is quite the job! Thanks for the view!
Nice video, heck I would play it again just the the Smooth Jazz music!
Thanks for the view!
I just had to have this done to my daughters 2012 JK, once was under warranty now the other head needed to be done out of warranty. Runs like new, nice time lapse!
Thanks! We have defiantly done a lot over the years!
Hello from Mexico City, my jeep has a left head factory problem and need change the piece. This video is a great reference.
Thanks, check to see if it is still in warranty, some of these got a extended warranty from Jeep, Thanks for the view!
I have a 2017 with less than 100k miles and that thing started to heat up I changed the entire cooling system the only thing left is to change the head gaskets I think a head may have warped but I don’t get no smoke or check engine light plugs are clean too??
this is very helpful
I have a 2013 ram 1500 with the pentastar and I gotta replace my drivers side head. Can I also bypass having to remove timing cover ?
Excellent work and video Tyler. Dealer is currently doing this work on the other side of the motor on my 14 ram 1500 due to overheating
Hopefully they get it fix for you! Thanks for the view!
I only drive vintage vehicles anymore. Completely rebuild them so they are reliable. This video shows why I do this.
Yes it seems every year they get more and more complex. Thanks for the view!
This video makes me think i could still do this at home. Im pretty handy. Ive got a 2014 durango and the heat rises when under load like climbing long hill. Had a misfire code in #6. Used head gasket sealer and that seems to have put a band aid on it, but still have rusing temps on long hills. Now im worried i might need a new head. No white smoke, but was getting air in coolant system.
We have seen a few with head gaskets failed after a overheat, we normally replace the heads and gaskets at that point due to warpage. Thanks for the view!
Great video. Just bought a 2012 knowing I would need to do this.
Nice! It's not a good how to but at least a decent overview on the job. Thanks for the view!
Lol me to! Bought mine about 5 months ago and knew this was going to have to be done to. Looks manageable
@@tylerlavely2317 I have still been driving mine with no issues, just a check engine light. It's not my daily, so the CEL doesn't bother me, the engine makes a faint tick on #2 cylinder but again not enough I'm going to tear into it and change the head anytime soon.
great job brother!
Thanks, and thanks for the view!
My girls 2013 JK runs a bit hot after driving for 30 min or so. It has never passed the 3/4 mark on the temp gauge. I replaced the Radiator, thermostat, and coolant temp sensor, all after flushing the fluid from the system. The Jeep seems to be running well, however we did receive a P0303 Code so now I am looking into replacing the spark plugs and coil pack. Looks like this job here is really what my jeep needs. I am not sure. I hope it is just the spark plugs. I guess a compression test would help my diagnosis this?
We see a lot of aftermarket thermostats cause overheating, I would start with a Mopar thermostat.
Do you know if you can take the right side head off with out taking off the front cover too
No unfortunately due to the timing chain tensioner location the front timing cover has to come off for the right head
Ok thanks for responds
Now do the passenger side! 😂😂 not that easy!
Yeah the darn timing cover needs to come off for that side lol Thanks for the view!
That was awesome.
Do i need to worry about the adhesive that was on the front of the head glueing it to the timing cover? I don't think i saw you put any on and i don't have the fancy dodge stuff anyway ha. Thx
Dude your oil cooler replacement vid helped save me 1300 dollars by giving me the confidence to do it myself instead of pep boys.
I'm really debating doing this job too but my biggest issue while doing the cooler was being able to reach the back of the intake! Are you 7 foot tall? Did you lower your jeep? Front bumper removal?? Please help lol
The cylinder head replacement requires the Mopar special tools, but yes normally I have my knees up on the front bumper. Thanks for the view!
@@TylerPotter what special tools are you using besides the cam phaser tool?
How much is the overall cost with parts and labor? Does this take care of the valve guide issue as well?
Cool Tunes.
Thanks for the view!
I own a 2014 Chrysler Town & Country. Cylinder head replaced twice. Code P0302 then P0306. Fails leakdown test. Might hear ticking sound early on. This is a common 3.6 Pentastar problem. There is a lawsuit. When I bought the minivan Chrysler offered the no longer available Lifetime Maximum Warranty.
Hey Tyler, great video! I’ve got combustion going into my coolant but no oil mixture. Hoping it’s just a head gasket. Fixing to take it apart next weekend and replace the head gasket. Is there anyway you could post a link or just tell me what tools you used to hold the cam phasers and the tool used the push back the timing chain tensioner? And any other specialty tools I’ll need on this project? Also, is the right side about the same steps or will I have to remove the timing cover? Thank you sir!
These are the main tools we use for the pentastar. The right head does require the timing cover to be removed. Thanks for the view!

I had this exact question, thanks for the reply.
Iv seen some shortcuts to not remove the whole timing cover and just the 1 bolt holding the top of the chain guide. Im just getting to lifting the head off the block now do you think i can get by without the cover coming off?
Hello, can You help me, The engine of my Jeep 2014 starts to heat up only when I start to climb a road. The radiator, the cap, ando the thermostat have already been changed, with the compression test it would be possible to check which head is damaged or how else can you find out which of the two heads has damage...???
With head gasket issues we will see A LOT of pressure in the cooling system really quickly after start up. They are sometimes pretty hard to diagnoses. You normally won't see low compression. But for the overheating you have already done the main things. Has the Jeep ever been overheated badly?
WHAT TYPE OF HEAD GASKET DO YOU INSTALL? DO YOU RECTIFIED THE HEADS?
I have only used factory mopar head gaskets. Thanks for the view!
Great video Tyler, I searched 3.6 vs 2.0 jeep and this video came up. Very helpful to see how it's all put together. What's your take on the classic 3.6 Pentistar vs 2.0 Turbo debate as far as reliability and longevity? Just curious as a master mechanic what your thought are. Thanks and keep the cool videos coming I just subscribed!
If I ordered a new JL tomorrow and couldn't get the 392 I would be going with the 3.6. There is just a lot more stuff that could have issues with the 2.0 due to the additional cooling system with the turbo ect. I think the 3.6 will give you a lot more worry/issue free miles than the 2.0. Thanks for the view!
@@TylerPotter Awesome! That helps a lot. I have been kicking around the idea of ordering a 392 and wanted to compare it to a standard rubicon. But given all the engine choices in the "Standard" rubicon it's hard to make an apples to apples comparison. But I think you hit the nail on the head, if you can afford a 392 then get it if not go with the reliable 3.6 Pentistar. Good news I have been saving money in my piggybank since I was 11 for a Hemi so I just have to find that hammer and break it open :) Thanks Buddy.
That is the correct thought, 392 if it makes since but if not the 3.6 would be the choice, one new option to think about is the Xtreme recon package with the deeper axle gearing and the 35in tires from the factory. Options options!!
Boa noite gostaria de uma ajuda sua sou Brasileiro moro na cidade de Salvador Bahia troquei as juntas de cabeçote do Jeep Wrangler 3.6 v6 e o mesmo depois de tudo montado não da partida o que será ?
Questions?? If you replace one cylinder head is it necessary to replace the other one. Also if you resurface one cylinder head should you resurface the other? Tia!.
This one was just replaced due to a burnt exhaust valve so only the one head needed to be replaced. If it was a overheated engine issue normally both heads would need to be replaced. Thanks for the view!
I have a 2015 right now! And it’s giving me a misfire on 4 and 6 and a P0430 below threshold bank 2
I’ve done a compression test by any chance what problems were you having?!
This was a misfire due to low compression.
Great video! What attachment did you have on your air tool when you cleaned the top of the block before putting the new head gasket on? I don't have an air tool but want to use some sort of equivalent but want to make sure it isn't too abrasive.
It was one of these that helps clean the block surface but doesn't cut into the aluminum, Thanks for the view!

Do you not have to worry about the chain coming off down at the bottom ? I have to do the same job most likely burnt valve cylinder 6
Not if the cover is still on.
Question: how do you move the timing chain and not mess up the timing, also what is that pin looking thing and spacer
Just saw a comment reply from an earlier comment! Thanks 🙏
Ever do this on the 2.0
So far we haven't had the heads off any of the 2.0's yet. Thanks for the view!
who polished the heads? And were they also ported at all? Nice video!
This was just a new stock head from Mopar. Thanks for the view!
Do you need to machine the surface of the engine block or not necessary?
It would be a good practice to use a straight edge to check for straightness but normally you would just clean the head surface and install your new gasket and head. Thanks for the view!
Do you happen to remember where you sourced the cylinder head? I'm about to have to do the same on my 2012.
It was a head from the Mopar dealership. Thanks for the view!
I've been chasing a P0349 gremlin and have tried everything I could think of. I'm afraid it could come down to the head. Can you share an estimate of the cost for this work so I can prepare myself?
About $3000
Nice video !!
Quick question, no angle torque ??
You are correct the factory spec is for torque then angle. Thanks for the view!
@@TylerPotter ok, i need to do the same work, left Side head replacement, want to know, if You use the factory method,or You just, torque to another final value.
Thanks !!
I notice you put the timing cover on with out rotating the motor,i am doing left side head as well so as long as my arrows are pointing each other on the phasers the two scribe lines are opposite of each other and there are 12 chain pins in between the phasers, am i good to go?
Valve cover*
I always mark with a paint pen my chains and phasers so I know they are going back on in the same spot.
So the time isn't replacing the gasket it's fighting through all the crap beforehand, and you just need to take it all off..
100% correct there is sooo much crap to take off 1st!
I’m getting my gladiator head replaced. Does it come with new lifters or are they going to use the old ?
The heads don't come with lifters so the old lifters are normally reused. Thanks for the view!
What is the diagnosis for the bad valve? Compression check? I have a 2017 durango with the same engine and a misfire but only at idle. Under load it runs great. Hard to believe I'm low on compression but maybe. Good video.
The burnt 3.6 valves are always low on compression on the affected cylinder. Thanks for the view!
@@TylerPotter My #5 has 0 compressions. I hope it was valve, not a piston.
Hey thanks for the video, what head gasket did you use. I would like to use a different than OEM.
I have only ever just used the factory Mopar gaskets. Thanks for the view!
@@TylerPotter Thanks for the answer. What is the red colored material on the gasket?
@@wetterman08 that is the Mopar gasket sealant aerosol spray that we typically spray onto new headgaskets before installation.
I am curious did you undo everything from the top? No oil pan dropped or anything like that?
Yes everything from the top, oil pan and timing cover stay on for the left side head. Thanks for the view!
@@TylerPotterdid you add more silicone to timing cover before putting new head on?
I had a misfire coming out of Cylinder 4 head from my 2014 JKU 3.6L Pentastar engine and my mechanic buddy told me I should replace my cylinder heads since during the leakdown test there was air leaking out of the other cylinder heads. My question to you should I replace the Timing chain also since I'm replacing my cylinder heads? I'm getting mixed answers saying since I only have 100K miles that I shouldn't bother replacing the Timing chain. Your thoughts?
We never have any timing chain issues, so I wouldn't feel bad keeping the original chains, Thanks for the view!
The timing chain should be fine but rockers and lifters need to be changed. Also check phasers on exhaust to see if springs are bad
Did you need to check if the block warped?
This one just had a burnt exhaust valve and was never overheated. So it just got a new head and gasket to correct the valve issue. Thanks for the view!
Hi, how are you? Can you share the cylinder head torque please?
Awesome thanks for the info.
Is it okay if i drop the timing chain after marking ?
Technically yes you can drop the chain as it won't fall off of the lower gear but I normally like to zip tie the chain up to the timing cover just for extra peace of mind. Thanks for the view!
What special tools did you use ? Was it a kit ?
Obviously I was using the Miller Mopar special tools at the dealership but these are the way cheaper aftermarket options. Thanks for the view!

Surprised you guys don't replace all those roller rockers. I've seen a bunch of them fail
When replacing the heads under warranty FCA will not let us replace additional parts unless the parts have failed, I did check every single rocker to make sure none of them currently had too much play though,
@@TylerPotter I figured it was warranty. I'm currently an Infiniti tech, I know the warranty game all too well but I used to work at a national repair chain and work on everything.
Nice, I've been with Chrysler/FCA for 12year now.
I will obviously not be doing this myself, but as for a shop doing it, how long would you say it would take? I drive a decent amount each day between school and work, so I can’t lose my car for to many days. How long would you say? Thanks for the help in advance
A technician that is proficient and used to doing this repair "should" in the best case scenario be able to get it done in one day pending not having to work on anything else. Thanks for the view!
@@TylerPotter I know they are doing this repair for other Jeep’s right now but on the opposite head of what I need. Is it practically the same
The other side requires the front timing cover to be removed to it is a little more involved.
@@TylerPotter How easy to separate the head from the front timing cover if not removed? I'm going to do it on a grand caravan.
how long did this job take you exactly?
It is about a full days job from start to finish. Thanks for the view!
What is the price in the dealer for Jeep sahara 2014 motor head.
I am not sure, I would get your VIN number and give your local dealership a call for pricing. Thanks for the view!
why did you replace it ??
Burnt exhaust valve causing a low compression and a misfire. Thanks for the view!
@@TylerPotter what special tools did you use ? Was it a kit ?
what did you charge?
Burnt exhaust valve causing a misfire. Thanks for the view!
@@TylerPotter Thanks, I was talking cost!
@@mikev1480 oh sorry I miss read that, I believe this one was still under warranty so it was free for the customer
Phwew! CHAMP!
Thanks for the view!
Yeah that’s a big job…imagine doing it without power tools
Yeah I am very thankful for power tools! Thanks for the view!
Once you’ve done that head then you can fix that leaking rad, then the front axle seals, then the rear axle seals, then the seizing door bushings, then the leaking rear wiper motor, then the clogged heater core, then the thermostat then the oil filter adapter housing, then the seized rear brake callipers, then the slipping transmission and repeat. Oh and now the other head needs camshafts for failed rockers. These vehicles are junk, assembled with parts made by the absolute rock bottom lowest bidder.
My 2015 jk same problem rocker and lifer fail. Dealer fix it under warranty and now off warranty the same cylinder head went. Jeep Wrangler are good vehicle just made by a shitty company. Now 2k to fix the problem with new cylinder head. Did my research and found out that jeep 3.6 under a class act lawsuit. For the same problem.
Yeah some of the early ones had the issue twice, Thanks for the view!
Damn I have a lot of work ahead of me. :(
Yeah it is a pretty big job! Thanks for the view!
@@TylerPotter I think the bottom end has major issues. Not sure what what to do but I think the head needs to come off either way.
Not a reliable car walk away from a jeep period :(
Thanks for the view!
