Your narration and pace make this one of the best auto repair/maintenance videos I’ve seen on KZbin. Thank you.

[@michaeledwards19]

Brother is on point...! He knows what he's talking about, even the areas where brackets and parts are missing from the previous "technician". If you're looking for a step-by-step guide to get you through this complicated maintenance action, you need to watch this and have it handy as you're doing it yourself. I had my phone propped up and went right along with him as he did it. If you follow everything he says, you CANNOT mess this up. The only thing I did differently is regarding the bracket over the most rear coil on the driver's side. I was able to remove the coil pretty easily without removing the bracket. Good job Sir...

[@bbwrs312]

Serious thanks to you for taking the time to make this video. This is the most clear and thorough video I found and I was able to get the job done in just a few hours.

[@DickeyJ2011]

Thank you so much for making this video. I just changed the spark plugs on my wife's 2018 Dodge Durango which has the same engine. Fixed her throttle issues immediately and saved me a ton of money. Would not have even attempted it if it wasn't for your video. So thank you again very much!

[@LesPAT-vj8kk]

I appreciate guys like this who don't take shortcuts and always pay attention to detail. After a house, a car is the next most expensive thing you might buy, so having a guy you can trust like this guy is awesome

[@PowerHouse_Exotics]

I'm at 93k on my 3.6. Just bought all the plugs. Also, an oil change. Glade, I watched this. Definitely saving money by watching this. Sucks cars aren't made to last these days. I'm so glad old cars still exist

[@bryonmoffett523]

This is one of the best videos I have seen tackling this project. The sound and video quality were great. Not too much BS during the actual work and showing the removal of all screws, etc. (but I liked that you showed each coil as a couple had variation). I also liked that you left in the bad parts (missing parts, dropped bolts, etc). I would recommend cleaning the internal part of the throttle body as well. Thanks! I'm going to do this one today!

[@conradb7200]

WOW!! You are absolutely amazing! Since I don’t go to STEALER-SHIPS, and am proud of myself for mastering the art of changing my own oil … I’ve learned a lot from The s excellent video. I now realize when my 2015 Jeep GC 3.6 Pentstar needs new spark plugs … it’s time to sell it!😢

[@Dusol7772]

Finished mine in 3 hrs following this video! Thanks!! That bracket over the back coil was the hardest part for me.

[@Dmckmaw]

I could have done this job without watching this video but you made it easy for me. It’s nice to know exactly what you need or don’t need to remove. Thanks. And thanks for the professionalism. I hate when guys try to be comedians and mechanics.

[@Rick-the-Swift]

I hear you, so annoying when they are like, "now we just need to get that nut off- and that's what she said - waka waka waka 🙆‍♂"

[@RoadiJeff]

I recently replaced the plugs in my 2018 GC at 100,000 miles, with much guidance from this video. It might seem overwhelming if you just watch the video and think you'd be better off selling it than trying to change the spark plugs but if you take it one step at a time the process isn't too difficult. It took me many hours of going slowly and a couple of refresher breaks but I did it and saved hundreds of dollars off the $700 dealer quote, including new plugs, PCV valve and manifold gaskets. Although not shown in the video, it is much easier to replace the PCV valve while the intake manifold is off and out of the way.

[@CarveLife]

Dealer just quoted me 1000. So I’m here lol.

[@TimMetling]

After viewing your video I think I will tackle the plugs on my 2017 Trailhawk. Thanks! You saved me about $600. The book said it was about a three hour job, bet I can take at least five to do it 🙂

[@alexespinoza4179]

How did it go? I'm looking to do the same on my trailhawk.

[@MrMuslesmarinara]

This is by far one of the best help videos I have ever watched. I had a bad ignitions coil, this video was a ton of help…. All information was thorough, and was from start to finish. Thank you, video was a ton of help for me

[@jasefiato9352]

Followed to a T! Got my spark plugs replaced with no hiccups! THANK YOU🙌🏼

[@jeffedmunds5]

Awesome video Austin, all of the stuff left off by the previous mechanic is why it pays to do it yourself and your video gives me the confidence to do it!!

[@EarlxWolf]

I used this video as a reference, all in all it’s a great video. Some of the bolt are the little plastic retainers(clips) that’ll mess up in order to do this job. As long as you don’t destroy them they are reuseable and won’t make any rattling sounds once finished.

[@drgil65]

Great video Austin. After watching all that work, makes me appreciate how simple my 99 XJ is to work on. 🙂

[@OutJeeping]

Thanks! I agree, there is a lot more stuff going on than the simple 4.0L.

[@DSplatter]

I had a 96 GC and it made working on cars look easy, I’m not looking forward to swapping my plugs on my ‘18 because of how long I know I’ll spend doing it…. Seems like I constantly have something to fix on this thing….

[@krisk1547]

Ok done. Took me 5 hrs and 4 trips to store because of missing tools and leaking camshaft sensor. It's good to change pcv valve as well since access is much easier with manifold off. Without this video i would probably break something trying to remove manifold 😂. Thanks again. Saved me few hundred $

[@stevestringfellow4141]

Great tutorial ! I needed to change the #1 coil, so I changed all the plugs while I was in there. I never would have attempted this without following your video. Thanks!

[@stevestringfellow4141]

@Jeff James yes P301 code. Scary running on 5 cylinders until I got home! Replaced the coil and all 6 plugs. Runs great now.

[@stevestringfellow4141]

@@jeffjames9568 Yes it was very rough, like it had a bad piston misfire. I was about 12 miles from home and 22 miles to the nearest dealer. Limped home keeping it at a higher RPM with the least vibration using my manual shift positions.

[@stevestringfellow4141]

@@jeffjames9568 It will come off. Try not to break all the insert clips. Use black Tie Wraps if the fasteners are broken during reassembly. Don't forget the rear Vacuum hose like I did.

Thanks. Ya had me at 4.0L "straight six". Subscribed. Got a '16WK2 going to do this with. Good vehicle . . . Well over 100,000 miles. Still strong. Just needs a spark plug change.

[@garyhanson638]

Very thorough, it's a lot of work for plugs, but made easier thanks to the quality of this video. Went well, saved a few hundred.

[@franks4973]

Very clear step by step. You helped me decide that even I could replace the injectors on my 2020 GC myself, I really don't want to. A mechanic looked at it for running rough and said #6 injector had a 2 million pulse width (strange) so maybe its shorting out, but he seemed to be completely guessing and I don't have any confidence in him

[@randygreenfield9741]

At 5:05 in your video I was doing the same exact thing you did and my clip also broke. I thought that was too funny. I had to share it. Your video is very, very helpful.

[@janderson1048]

Great video, thank you. Saved me a couple of hundred dollars doing it myself . I have a 16 jeep Cherokee, everything worked to a tee!

[@marcoscardenas8813]

This was a great step by step video. I’m tackling this job today on mine. 🎉

[@JD_Spencer]

This is not an easy job and its worth it to take that cowl off i think. Still pondering that one. I did lose 1 10mil as well. Its just really tight and youve got that bottomless cavern behind it just waiting for you to drop a screw or socket. T😢his and oil filter housing is rough. Great vid

[@joebwhite]

Hear hear - this is a must-see for anyone deciding whether to tackle changing the sparks in their 3.6 Pentastar-equipped Grand Cherokee. This is not a simple job - I would have been lost without this. Austin, if I could make a request for a future video: A how-to on swapping out the variable valve lift solenoids on a 3.6 Pentastar. They sit on top of the cylinders - it's job you could do after stripping down the engine the same way you did for the spark plugs. But the connectors on those are tricky and advice on how to diagnose problems and get those out without causing damage would be much appreciated.

[@OutJeeping]

I'll look into doing those! Thanks

[@MM-sq5pf]

Awesome vid. How do you know how to do all this? Reference books?

[@parker7161]

How did you get the connector off the ignition coil? I can’t seem to get it off

[@stlpatch25]

Thank you so much for the helpful video. Had it done in less than 2 hours. Great job on the video!!!

[@johntip6935]

Followed directions but had a heavy hand. while disconnecting the breather tube going to the back of the engine, I pulled it a bit too fat and cracked the PCV valve. After putting the parts back together and going on a road test The service engine light came back on, then the warning light for the traction control flashed red! I found that driving back to the garage the vehicle went into "LIMP MODE", causing me to drive back at 35 MPH with the pedal to the floor! Had a bunch of diagnostics codes pop up! The main one was a vacuum leak! Since we did NOT change the rings on the intake - we assumed that was the cause. We took the entire thing back down, changed out the rings, torqued the manifold to 74-inch pounds, and still had the same issues. Finally found a tiny crack in the PCV valve. We replaced the valve, cleared the codes, and the 3.6 was running smoothly! Be really careful when pulling on the PCV TUBE because the valve is all lightweight plastic! LESSON LEARNED!

[@OutJeeping]

PCV valves should also get replaced every so often as well. They can get dirty and not work that great over time. Glad you figured out the issue!

[@safdaralli2567]

I'm so glad I'm reading this...thank you thank you for the warning...haven't tackled mine as yet..but will pretty soon..just looking at videos to get an idea....now I know what to do and what NOT to do..

[@hectorgil12]

@OutJeeping which one is cylinder 5? I have a misfire and are going to try to do this my self. It’s way easier on a Yaris than a v6

[@RoadiJeff]

Even number cylinders 2, 4, 6 are on the left (driver) side. Odd number cylinders 1, 3, 5 are on the right (passenger) side. Start counting from the front of the vehicle.

[@jungminlee2386]

Thank you for your video. It is really helpful when I need to replace the spark plug. It seems like you have VVT solenoid seal has oil leak. Any more video to replace the seal?

[@OutJeeping]

Not at the moment. I didn't notice it was leaking or looked wet till you pointed it out and I rewatched the video.

[@dronetherapy5800]

I have noticed leak as well and mine started to leak from the same spot, not sure if it’s a valve cover gasket

[@jimrusch22]

After watching this video, I think I’ll have someone else replace my plugs. Why can’t manufacturers figure out how to make electrical and mechanical connectors that don’t brake and become as dry as a popcorn fart after 70k miles?

[@Superbonker-np6iz]

I have just been quoted $700 to do plugs on my 2016 Grand Cherokee. That doesn't include anything that gets broken while plugs are being replaced. Jeep as well as other vehicle manufacturers don't want you working on your vehicle and make it as hard as possible to do any regular maintenance. By the way tranny service on the same vehicle is $1300. I will never buy another Jeep ever again.

[@demarionh4895]

Be careful with the hose on the canister purge valve! My 2018 jeep the hose was very brittle from the heat and I barely moved it and it broke. My repair method also was to get a hose and clamp both ends of it so seal it and it worked instead of having to buy the whole assembly

What is that engine foam piece Mopar #? Also, that sludge buildup piece was for the EGR valve.

Not sure on the foam piece. You should be able to look it up on a Mopar parts website.

[@Fr0sty4242]

Did you replace the intake manifold gaskets?

[@OutJeeping]

I did not, but not a bad idea to replace them while it's all apart.

[@matthewcalcaterra6616]

[@OutJeeping]

Basics hand tools. A wrench, ratchet, and screwdriver set will get you going. And a spark plug socket.

[@JTaNay93]

Hi Austin! My husband has a 2018 Jeep Grand Cherokee Trackhawk and he is wanting to change the sparkles himself. Is this process similar? Does the different engine matter much? Thank you!

[@OutJeeping]

Yes a different engine would be a different replacing process. This video only helps if you have the 3.6L V6 engine.

[@TjRoss2012]

Sir is there anyway you could provide all the tools required for the job? Thank you so much! Awesome video btw

I got a 75th Anniversary Edition 1941. Newest car that ever had. Didn't need the Sparkles would be such a pain. Not to mention everything is plastic brittle and breaks. First time I ever seen a plastic manifold. Not only that. The bolts to the manifold look like they're threaded like wood screws. The heck with all this proprietary stuff. I bet if you took it to the dealership they would charge you $500 just to replace a spark plugs. I really like this Jeep it drives good best car ever had but man. I'm in the middle of it right now, and I'm putting the manifold back on, and I'm just worried about cross threading the wood screws. Any advice on that?

[@OutJeeping]

I wouldn't be too worried about those screws just tighten till it snugs, they don't need a lot of torque.

[@barfallenmule]

Thanks man. I'd rather be replacing an engine on a 67 Mustang then replacing the spark plugs on this Jeep. Lol.

[@OutJeeping]

@swimers100 Is it sputtering, or is it clanking for the first second or 2? It's common for all 3.6L to clank for the first 2 seconds on start up where it sounds like it has no oil.

[@swimers100]

@@OutJeeping dang I need to check the oil but yeah the steering wheel shakes( not too rough ) and the engine too for a good 2-5 seconds after turning on. Then smoothes out. Might go to AutoZone to check the engine light. But just wanted to hear your thoughts first.

[@OutJeeping]

@swimers100 Well it's a common issue that they all do. Even with the oil at normal level. The engine design allows oil passages to drain back into the pan. So the first couple of seconds is the delay in the oil getting pumped back to the top end of the engine.
