How to Change Spark Plugs Jeep Grand Cherokee 3.6 V6! 2014+ WK2/ Not much to add, but this is a lengthy process !

[@willfrancis3340]

As an aspiring diy-er, this video slowly became pure comedy as I began realizing there's a zero percent chance at doing this successfully myself.

[@LJsGarage]

Haha I love the honesty it was a rough one 😅

[@jorgepino3676]

I felt the same way until i decided to do it.. after not able to pull out thr air intake on Sunday.. i left it all taken apart until Thursday and i finally got it out. It takes lots and lots of pulling

[@realityhurts8697]

You can do it, it's just alot of little details

[@LootenantXan]

I am 100% confident in my abilities, and I am already irritated realizing I have to pull the manifold to get the driver side plugs.

[@weldingjunkie]

It’s very simple you can do it.

[@robertgelley6454]

excellent video! Straightforward and to the point without all the fluff. A+

[@LJsGarage]

Much appreciated! Hope it helped 🤞🏿

[@joshua7680]

I recently had to do the oil cooler and filter housing. Used this video as refrence because I decided to do my plugs and coil packs while I had it open

[@LJsGarage]

Awesome, glad you made it through! Hopefully not too much blood and tears.

[@jordanbennett3814]

Just finished replacing the ignition coil and spark plug on cylinder 6. Not a fun job, but definitely beats taking it to a shop. Thanks for the tutorial!

[@LJsGarage]

Nice work! Glad it helped :D

[@devinsheremeta1513]

Hey, which one is cylinder 6? Were you getting a misfire code? If so did it solve the problem

[@katiepalfini2979]

Welp guess I'm not doing it myself. Good description though.

[@LJsGarage]

😂 not going to try and convince you... It was not fun

[@TheVaka1]

My same thoughts 🤣🤣

[@boeboebaggins]

This seems overly complicated for replacing some damn spark plugs. Thanks jeep 😒 Nice video btw!

[@LJsGarage]

haha thanks and yeah wait till you see the O2 sensor...

[@SSHitMan]

@@LJsGarage I took one look at where the O2 sensors are and then took it straight to the dealer. 😳

[@atarisbetter9199]

​@@LJsGarage once you get the intake tube off why can't you just replace the plugs on that side? It looks all open?

[@timwoods1771]

My thoughts too.

[@Kiddro22]

Try Removing the starter on a NorthStar engine......Smh!

[@matthewjswider]

What this guy left out: The nuts under the intake plenum on the right side (driver) are 13 mil The rear nut has a bracket on it for the condenser lines. You’ll need a long handled 13 box wrench to get it loose, flipping it back and forth each time. The 8 mil screws (7) that come out of the top of the plenum need to be completely removed, especially the rear one. The last two hoses can be removed after the plenum is halfway out. If you loosen the brackets with the 13’s enough and slide the plenum to the right it will come out of the bracket behind the throttle body.

[@LJsGarage]

Appreciate you my friend!

[@matthewjswider]

@@LJsGarage no problemo man. It may be DIY but we are all in this together. Human kind. :)

[@lanceprzybyla7662]

I'm doing this now...thank you 🎉

[@aaronolson762]

Yes, good catch. It was a pain in the ass for this part

[@JeffKleinSystematic]

​@@lanceprzybyla7662how did it go?? Looking at this myself after Jeep quoted me 942

[@weldingjunkie]

Good video, the back bracket is a 13 mm at the bottom.. we also forgot to tell them about the 210 mm on the right hand side where coil 6 is….the only thing you didn’t have to do was you could’ve left a throttlebody on the intake itself. That’s what I typically do. Service data calls for 1.7 to 2.0hrs but can be done in 1 obviously not filming of course lol that slows it way down.

[@LJsGarage]

Good tips man much appreciated!

[@kuvasz101]

I just changed my plugs 2015 3.6 Grand Cherokee. I don't see the need to loosen the 2 lower bracket nuts on the driver's side. I removed the 2 nuts that attached to the 2 intake studs on the driver's side.

[@LJsGarage]

Yeah I realized that after for sure thank you!

[@ThomasChapman6298]

The air suspension is one of the best features about the car imo I’ve been driving the 2014-2021 3.6’s two different ones a 2014 and now a 2015 for maybe 6 years now. But you can easily take on 8” it’s a great off road car great for mudding if you want to the only problem is you only have about 8”-1’ till you’re cutting it close to the bottom and a full skid isn’t standard so I would do any serious off roading like you’d do with a lifted wrangler where you’re driving over boulders and huge divots, but there’s still a lot of land you can run on.

[@LJsGarage]

Great point for sure can't argue!

[@pontiacsrule8761]

Great video BTW. For you guys or girls needing to do this job, try watching the TRQ video. I like the TRQ company and their videos. Watch this video & TRQ & see which procedure you want to follow? They have you remove the cowl, the wipers, the transmission for the wipers & on & on. Thanks for making this video. I will be following this video for sure.

[@LJsGarage]

Thanks for the tips! I will also be taking a peak at that method sounds worth while in some ways

[@907GIRL-t1v]

Seems soo dam easy but it's intimidating. The submitter is doing an awesome job but I have no confidence. Thanks Jeep!

[@LJsGarage]

You can do it! Thanks for the kudos 😀

[@907GIRL-t1v]

@LJsGarage the 3rd spark plug is in back & under. It's the one that quit. Soo I'll have to dish out $$800 for a shop. All good! If I was a mechanic, no problemo. Thanks for the encouragement tho!

[@kikerules]

hello, kinda related , oil pressure sensor for that car , is it located inside the manifold ?

[@LJsGarage]

Right under it sadly

[@daveprostine1055]

what oil cooler housing did you go with? there is that aluminum one by dorman that I've heard good and bad. mine weeps oil only when it gets really cold so having the dealer do it along with the plugs and coil packs as I like the vehicle.

[@LJsGarage]

I used the same OEM one and it leaked again 😒

[@michelecourtney4226]

How long did it take in real time to remove the cover etc. to get to plugs?

[@LJsGarage]

About 2 hrs actually not fun but doable

[@emgangofficial5671]

Why you removed the throttle body ?

[@LJsGarage]

To make more room. it makes it easier to get to the last two plugs

[@moisesjasso7209]

What should a spark plug be gap to? I have a 2017 Jeep grand Cherokee Laredo 2 Wheel Dr. 3.6.

[@LJsGarage]

.043/.044 gap if I recall

[@jorgepino3676]

Does the air intake case needs to clean?? Also why is there so much gunk in it?

[@LJsGarage]

Not usually and probably because this one had a rough life

[@JoseHernandez-nf4ep]

Have you done fuel injector replacement?

[@LJsGarage]

Luckily I have not 🙏🏿

[@justdagoatgaming8460]

Did you disconnect the negative part of the battery first?

Evap Purge hose I believe you are talking about

That is the purge. Mine easily cracked awhile back and had to replace whole unit.

[@jorges1744]

Do you have to replace the intake manifold gaskets when doing this?

[@zacht6787]

No, unless you notice they're messed up - either seal isn't right anymore, it's cracked, or broken

[@zacht6787]

If there's like 200k miles might as well replace it anyway since you'll be that far into it though

Depends on the mileage you're at might as well

[@billwatcher9321]

Believe me, you do want to use a touch of anti-seize. Never trust "pre-coated". It's a really bad feeling in the pit of your stomach when the aluminum threads from the cylinder head come out with the plug !! Anti-sieze is very cheap insurance !

[@LJsGarage]

Understandable lol I have been alright so far, but I respect what you are saying

[@brentfodera377]

Sure, it’s a fairly involved process, but in the end it’s just a sequence of bolts, screws, clamps and connectors. Nothing high tech. Just do it in order. Let’s say you normally earn 25 an hour, and you’d pay 600 for the job. Thats 24 hours, or 3 full days of work. It’s well worth it to do this yourself, and it’ll probably take no more than 5 hours for the least capable person.

[@brentfodera377]

And thanks for posting. It’s nice to have an idea about the scope of work before getting out there and figuring it out as you go.

[@LJsGarage]

You're very welcome my friend and absolutely true step by step and reverse!

So ✍️ completely break down the engine ✍️ drop a 13 pound weight on it ✍️ and then have a seizure because you forgot how you tore it down. Got it! 😂

😂 it's a hot mess.

[@Zenforya]

You miss the chance to show us how to get to the hard screw

[@LJsGarage]

It was tough to film sorry!

[@kuvasz101]

This post is not accurate. You do not need to loosen the lower bracket that attaches to the intake. This is an extra laborious unnecessary process.

[@LJsGarage]

Thanks noted for next go around
