How to replace the Spark Plugs on your Jeep 3.7 V6

[@Jeff-qq1tz]

Thanks so much for taking the time to put this together. Changed the spark plugs on my ‘04 Liberty today with your video.

[@killawattgarage]

Glad it helped

[@ryanwilson6162]

This is a very high-quality how-to video. Nice work!

[@smurf6326]

Than you for this video,I'm not very good with mechanics but watching this video I was able to change my plugs on jeep Cherokee KJ Thank you, you are a legend.

[@SmallTownSmokie]

Am I the only one who yelled “Well there went your ratchet!” When it fell and he kept talking. Lmao

[@killawattgarage]

HAHA! 0:39 I had to go back and watch, to figure out what you we saying. I actually film then do a voice over otherwise all you would hear is my cursing and yelling.

[@SmallTownSmokie]

Killa Watt Garage lmao right!

[@AnthonyLemus]

I came for this comment.

[@SkinnieHehe]

This was super helpful but thank you for including 0:40 that made my day

[@elisabethjensdatter7804]

Thanks!! Got the number two cylinder down and now I’m onto four and six before doing the easy side. Wish me luck and no more check engine lights!

[@killawattgarage]

well done

[@heyhey2576]

Had a exhaust leak on my 2010 liberty for a while. It started to miss i fixed the leak but its still missing. throwing a misfire on cylinder 2 code. going to try changing plugs next. thanks for the video watched to see what i was getting into 😆 wish me luck

[@dtellado1]

Don't ever drop your sparkplug in the cylinder. Use an old sparkplug boot and lower it down. If the plug hits the side it will change the gapping in the plug. Or buy yourself a sparkplug socket with the rubber inside, so you can lower the plug and twist it on.

[@killawattgarage]

Agreed!!

Great video. Thank you. Changing an 03 liberty tomorrow. Subscribed 👍

Bro love your video. Thanx so much

[@killawattgarage]

Thanks and welcome

[@MrDogon-mk3xe]

Thanks for the video, great and clean work, i will try on weekend

[@TaylorKMade]

I can definitely do this by myself thanks!

[@killawattgarage]

awesome thanks

[@kennethwolf3637]

You can use coils to get spark plugs out once loose.

[@killawattgarage]

Great tip, thanks

[@mastcaf]

Very good!! I have 2 questions 1.what is the gap of spark plug? 2.How to clean the coils?

[@killawattgarage]

99% of the time they are spot on from out of the box. Checking them is always a good idea but be careful not to damage the iridium tip on certain spark plugs. 0.042 in / 1.1 mm is the recommended gap. Spray on Brake cleaner will quickly clean up any traces of grease and oil. Make sure its dry before reassembly

[@stephensparks9350]

That was my next question too. Thanks

[@japa9991]

Gonna do it soon. 05 Liberty. Why does Jeep make it so hard? Had to replace my rear wiper and had to get it from the Dealership because Jeep uses some funky attachment that nobody else uses. I had to pay 3x the price for an 11 inch rear wiper. Don't even get me started on the replacement of my head light a month ago. Had to basically tear down the front end to get to the bulb. I still love my Jeep just not working on it.

Original spark plugs for jeep is champion right, NGK it's more for Toyotas , Hondas

[@richardlopez4459]

Being 100% new to trying to work on my own vehicle I have questions about the details regarding the tools used. What size ratchet is being used? What is the size of the spark plug removal tool What length is that extension? Are all the sockets used in this video usable on the same ratchet? I may have screwed up some of the terminologies even in typing this question.

[@JackTheAviator]

5/8 socket for plugs. 10m for bolts for boots. Probably 8 to 11 inch extension I would recommend a medium length bolt breaker as the ratchet to remove plugs. Makes it a million times easier

[@richardlopez4459]

@@JackTheAviator Thank you!

[@stephensparks9350]

You nailed then all man.nice job. Whatever happens in the garage, don't get frustrated. Keep going. You'll get there

[@joegonzalez1941]

Dont forget to remove the negative from the battery, you're working with live electrical system, just.a precaution, you wont short circuit something 😢

[@boydritchie3517]

Video was helpful but you should let people know you have to pry up on the coils.

[@sayedzeidan6254]

Greeting from Egypt I would like to know can I use plugs with four heads Bosch for jeep k k car

[@killawattgarage]

Yes you can

[@sagedorantes2766]

i have a cylinder #2 misfire. does it matter what coil i get for the replacement? or do they all work for the same cylinder its just a matter of getting a new one?

[@adamhinton6502]

Is it important to gap the spark plugs with a feeler gauge? I've heard this but wasn't sure if it was necessary.

[@killawattgarage]

99% of the time they are spot on from out of the box. Checking them is always a good idea but be careful not to damage the iridium tip on certain spark plugs. Also modern coils are fantastic and there are not the issue that we had years ago with weak sparks from distributor and single coil systems. Thanks for the question.

[@squintsquiby1295]

Can you link the tools used? I’ve been trying to use a small wrench for the 10mm nuts with no success.

[@franciscoayon9470]

I had a question,could I used a different spark plug? It says v prower,but been reading that the ngk iridium gives better gas mileage and so on amd also last longer,you think I could use it or need to stay with the v power one

[@killawattgarage]

The iridium plugs will also last longer. Give them a go. Thanks for the question.

[@franciscoayon9470]

Thanks for the reply,the only thing it's that their about 14 each

@@franciscoayon9470 If you are keeping the car then spend the extra $$ as it will save you in the long run.

[@rogerthedodger940]

Wow how mint is that Motor... All the plastic insulation has gone on mine and the Coil Packs are filthy... Is this a new engine or something... Only 2 sets of plugs 150K... LOL

[@jamesgilbert451]

Rite on ! Easy Street! Thanks

[@miguelangeljauregui4030]

Somebody told me that I need to calibrate the sparkplugs before change them

[@joegonzalez1941]

Double check the gap, with a feeler gauge, sometimes the spark plug has been dropped

[@odiriletlale9966]

Do you need to disconnect the negative battery terminal?

What is the correct gal on a 07 liberty 3.7l

[@dinosalihovic5015]

What sized socket did you use. 9/16?

[@killawattgarage]

Just used a spark plug socket

[@Tobias]

5/8 inch, 16mm is too big and will damage the plug, making removal a bigger problem.

[@woah2.090]

There’s one piece of the coil that’s stuck, how do I get that piece out?

[@japa9991]

Pour sand in it. The grit will match and will unwind.

[@LCCadle]

What should the gap be?

[@killawattgarage]

best to leave them gapped as in the box

[@rickyhidalgo1426]

What's the gap?

[@killawattgarage]

Best to leave them gapped as in the box particularly if there are iridium plugs

[@TheSchmed]

My 3.7 (Jeep Commander) has no trans dipstick, they cap it. Cheap wankers.

[@killawattgarage]

very typically these days

That's the same one I have (2006) a rare model. Turns out you have to take to a dealership to have the fluid checked.

@@killawattgarage Do I need to gap them?

[@killawattgarage]

@@allenbay4974 Typically they are gapped correctly out of the box, but its good to check.

[@kingchihuas1]

What size socket ?

[@Tobias]

10mm for the coils, and a 5/8 inch deep socket for the plugs. Here he is using a specific "spark plug removal tool" which is equivalent to the 5/8 inch deep socket. I suggest that and a nice lengthening adapter. One note, a 16mm deep socket might feel close, but it is a bit too loose and may damage the spark plug and be a much bigger problem to remove after.
