YOU SAVED ME, BRO.... THIS JEEP IS A PUZZLE. not a mechanic but I know my way around a car. The first car I have ever seen this setup. BUT the best video is well-explained step by step. Thank you.
Tips not criticizing. It’s a good idea to air hose off any sand and dirt prior to disassembly. If no air use hose use water to blast off(cold engine) then drive to air dry. Keeps dirt out of engine. Use blue shop towels in air holes after removing to keep dirt and everything out of engine. And it advisable to not use any power tools installing plugs and always torque to 13ftp . Just some tips because when I worked at dealership we loved folks who messed up great video to help folks though 👍🏻
Thank you
Thanku awesome video u just save me $900 that the dealer wanted to charge me for that... Is by far the best video well explained step by step keep doing some of those videos on Jeeps please thank you
Edgrr Gonzalez thank you. I really appreciate you comment. Glad I can help. If you need any specific job leave it in the comments and I’ll do my best to do a video about it.
Excellent, excellent video! This saved me a silly amount of time trying to figure out how to get to the oil cooler. Thanks for doing this!
Shawn Freundschuh absolutely. glad I could help.
Me and my son are going to try doing this. Thanks for the details!!!
That’s amazing. My sons are 3 and 4 now. Can’t wait until they can do stuff like that with me. Good luck. Plz let me know how it goes. Thank you for watching.
You sir are my hero today ! Ty ! I subscribed!
Thank you for washing and subscribing and I do appreciate your comment. Have a great day.
Thank you for the info. It was very helpful. One of the intake manifold bolts snapped when I had it half way in. Not sure why there was no tension on the bolt. So be careful. No one local has the bolts in stock. I now have to replace the inner intake manifold because that's where these bolts screw into. So be very careful when tightening these bolts.
Thank you for watching. I do appreciate your comment and feed back
These bolts are required be installed with a Torque Wrench, 7-9Nm. Also tighten in a specific pattern.
Removing the throttle body does give you some more room to remove the left rear hoses and also a bit more room to wiggle the intake manifold off the engine. Great video though!
Thank you.
100% agree. Makes job FAR EASIER!
Also a good time to clean it.
Very nice video Very detailed, learned something from your video 📹 😀 cuz I have same engine 3.6 L
Thank you for watching and I do appreciate your comment. God bless.
Should've changed the coils too. Awesome video.
It’s a good idea but not every customer wants to pay for coils on top of that bill.
Gonna be doing this tomorrow on my 2011 GCL! Wish me luck!
Good luck man. Let me know how it goes. Don’t hesitate to ask questions if you have any issues. 👍🏻
Many thanks from Russia for this video :)
Д Ш greatly appreciated
Very helpful thank you!
You’re welcome. Thank you for watching. I appreciate your comment
great job 👏
Great video, and I see that I have to invest in new tools. Thanks
Thank you for your comment. New tools are always good to have, makes the job a lot easier if you have the right tools.
I think I'll invest in a mechanic instead
@@PatNim73 lol. That’s another way to do it.
What kind of pry Bar is that?
A2Z Auto Master - After cleaning the throttle body on the 2012 Jeep Grand Cherokee 3.6L Pentastar V6 how do you do the idle relearn?
good job
very amazing video guys. is there any video for changing starter of this car in shortcut without removing many parts !!
Thank you for watching and I do appreciate your comment and feed back. I have done few of these starter motors but unfortunately I never had the chance to record any of them.
Awesome 👏

So much for torquing them spark plugs properly
Just bought 2012 cant believe that .. crazy
It’s. some cars are nightmares when it comes to regular maintenance.
Looked very tight removing the hoses and sensors in the back even with your tool. Was it easy to put them back in? I am thinking of doing this with my 2012 grand Cherokee. It’s giving me the P0420 and saw that most of the time it solves the issue replacing the intake gaskets. What are your thoughts? Thanks for the awesome video!
Thank you for watching. It’s a tight spot but doable, take your time and be patient. Btw P0420 is a catalytic converter efficiency code B1. Code has to be diagnosed right first but in most cases cat/converter need to be changed. Check with your local jeep dealership the Cat/converter should be covered under warranty by law if you have less than 100K miles. Let me know how it goes.
i know Im asking the wrong place but does someone know of a method to get back into an instagram account?
I was stupid forgot my login password. I would love any tips you can give me
@Luca Hugh Instablaster :)
@Andres Sergio I really appreciate your reply. I got to the site on google and Im trying it out atm.
Looks like it's gonna take quite some time so I will get back to you later when my account password hopefully is recovered.
@Andres Sergio It did the trick and I finally got access to my account again. I'm so happy:D
Thanks so much, you saved my account !
I don’t recommend using an air ratchet to install spark plugs. You can cross thread them. Install them by hand first so you can feel the threads going in correctly.
You’re correct but if you been doing this for years you know exactly how it’s going in right away.
@@a2zautomasters862 I understand that but your viewers don’t.
Thanks 4 the vid. What was total time needed to remove intake manifold?
Thank you for watching and I do appreciate your comment. I did this so many times, it literally takes me about 20 min now to remove the manifold.
Good gob
Did you also reinstall all those plastic clip attached to the engine that you remove using a pry bar or you just leave it hanging ? I'm just wondering . looks like it is hard to put them back.
Yes absolutely. Some of them might break but whatever is good goes back in place that what keeps the wiring from moving and getting damaged.

Du you have video that how can I change the pcv valve to the same car
hassan aldossari I don’t have a video just about the PCV but if you remove engine cover, remove hose from PCV and use a short T25 I believe with a 1/4 ratchet and take your time it’s tight but doable. U might have to move the wires back there just a little. It’s on the back of the pass side Cyl head on the valve cover it self
@@a2zautomasters862 full thanks for your help .
hassan aldossari 🙏🏻🙏🏻🙏🏻
@a2z Auto Masters - What is the name and brand of that tool you used to remove the intake manifold screws and spark plugs?
Power ratchet. They come in 1/4 in and 3/8 drives. It’s made by SnapOn
@@a2zautomasters862 I’m sorry what’s the difference? I want to get this for my husband for Christmas
@@celinacastro4831 it has a different size head. 1/4in is smaller and weaker for smaller bolts. The 3/8in is more powerful for Stronger bolts.

Which Milwaukee M12 ratchets are you using? 3/8” or 1/4” or both? Thanks.
Thank you for your question. These are actually SnapOn ratchets Not Milwaukee. They do look very similar and yes. I have 1/4” with a long neck and 3/8 with a short neck that I used in that video. Thank you for watching
Is there any way of getting to the camshaft position sensor without taking the intake off?
Only B1 the pass side not the driver side
While your at it remove the intake manifold and replace the oil cooler with a after market all aluminum , your original one has a plastic bottem.
I was having a cylinder 4 misfire so I decided to change all the spark plugs and coil pack just cause. After everything was done I still was a getting a misfire. Any idea what it could be? Tomorrow I’m changing the fuel injectors and replacing the intake manifold gaskets since I didn’t do that when I did the spark plugs.
luis verduzco most misfires I’ve seen with Chryslers was mostly an Ing coil, but since you changed it you will have to diagnose it right. Injector, vacuum leaks, power issue to coil or injector. But before you do all that you need to do a compression test. I have seen a fair amount of them with low compression issues. Valves problems
If it is easy to get to, Swap two coils and see if the misfire changes cylinders.
my 2007 jeep would tell me codes from the dashboard and I found I had a bad coil.
hello did u figured it out what was the problem cuz my jeep says the same thing but cylinder 1 is misfiring but we change the coils gasket and all that
What are the name of those 2 sensors on each head at the front on the valve covers?
Some call them solenoids and some call them magnets
Is the headgasket in the same place where the spark plugs are located?
Head gasket is a major job in this car. Probably 25h job by the book. I have other videos about the valve cover gaskets and timing chain jobs for the same engine. You can watch them and will give you a great idea of how big is a head gasket job.
For specific years of the 3.6, the manifold gasket around 200-220K miles needs to be replace.
Whats the torque on the coil packs if there is any?
13 ft
I can see why the 13 mm nut was missing on the back of the R bracket on the one you did here. There is like a clamp for the metal tube over the bolt that blocks access to the nut. I literally can't get it off and am about to give up :( Help ... Thanks :)
Yea that’s true but few times I’ve seen another nut on top of the metal clamp. Just use a pry bar and pry the clamp off.
I’m having that same issue too
how can a regular person remember how to connect all them wires by the time you're done you can't remember everything.
I got you. That’s why I make these videos to help everyone out there. Thank you for watching.
so the foam piece under my intake was all eaten by rodents , i reassembled without it , do you think its an issue
No it shouldn’t be an issue. It’s ok
how long should manifold job take ? 2 hours ?
Honestly I did so many of them, it usually takes me about 20 min to remove now
Did you have to remove another 13mm nut in the back aside from the two 10mm?
In that specific video I didn’t but you can remove it or even loosen it halfway it will help.
Thank you, what I did was remove the 4mm bolts that were sticking out of the intake manifold. Thing came off easily after. It was completely unnecessary to remove the 13mm i mentioned
@@matthieuratrimoson3271 perfect. Yes I do this sometimes too. Good luck.
Does the V8 require all that disassembly for access to spark plugs ?
The V8 is different. The manifold doesn’t cover the plugs. It’s much easier
@@a2zautomasters862 Thanks for the reply.
Just watched some other video and learned that but also learned that the HEMI has 16 spark plugs. I don't know if they even need to be changed. LOL!
I just got a used 2012 JGC with 90K + miles, Should I go with OEM Mopar plugs or NGK Iridium plugs ?
No issues with the car just figured that I would go through the easy stuff, Plugs, Filters, Oil ... Ect.
@@ronhobyak9902 true. They got 2 per cylinder. How many miles u got ?
@@a2zautomasters862 90K +
@@ronhobyak9902 @ 90K it definitely should be changed. Just pull one out and take a look.
Does anyone know if I should use dielectric grease?
You could. You really don’t have to
Where is your EGR located on that vehicle?
Some models aren’t equipped with EGR valve.
What’s that powered ratchet you’re using??
Looks like a snap on. But Milwaukee makes one as well and waaaaay cheaper.
Snap on.
Hi, How much should it cost to replace the spark plugs?
Someone was telling me he was @ the dealer last week and they charged him 4.5h X $185 per hour that’s $835 just for labor plus parts. I charge $400 for parts and labor.
@@a2zautomasters862 last year they quoted me $1500...no way... Since covid I haven't driven too much but need to take care of this soon. Thank you for you prompt reply!
@@alessandra9394 wow $1500. That’s Insane. Thank you for watching.
What spark plugs are original to this vehicle?
Mopar which probably autolite or champion
I swear to god the people dat design these vehicles must have been drunk honestly they weren't thinking of how to work on these vehicles
Drunk or have some really serious woman problems
How many miles on the old plugs?
About 60-70K Mikes
@@a2zautomasters862
Thank you.
Old plug gap seems a little on the wide side.
Old plug gap gets bigger as the tip gets worn.
You didn't gap those plugs, spec is .043, and you didn't mention the plug torque
We use high end spark plugs. Platinum and iridium spark plugs come pre-gapped and you don’t have to mess with it. The plug torque is 13 FT.LBS. Thank you for watching.
What mechanic wears an Apple watch will working on an engine?🤔
Yup. That’s me. Series 6 Gold edition. Actually just realized that was the older one I have.
That really is a pain in the ass
Chrysler for u. Lol
Is it my imagination or is this a silly design as to the layout of this motor. 1) Air intake / filter as far as possible from where the air enters the engine. 2) Large plastic manifold that needs to be removed because it covers access to the other side of the engine including the spark plus. Absolutely no design concern for maintenance work. Looks like about a 40 minute job or more just to get access to the other 3 spark plugs.
You’re 100% correct. I wish engineers can just do like 5 years hands on on the field before engineering school. Only then they might think twice before designing something like that.
WAY more than 40 min if you're doing this at home!!
Jeeps are junk so dissatisfied with my 2015
It seems to be a hit and a miss. Some ppl love them some just hate them. I do love them they keep me in business. Lol
Dammm i give up
