Do i have to disconect the batery cables before doing this job?

les c says:

Dude you are awesome! Changed plugs and coil packs today took no time and
my jeep is purring again!

howard ashcraft says:

man thanks, 

Stephen de Vries says:

Thanks, helped a ton. 

John Zollner says:

Just an after thought. Jeep of that model ( as I have the same one )
requires NGK plugs as from factory. Use anti seize compound or you may have
trouble changing them in future. Remove coolant reservoir and those pesky
back plugs will be easy as rest of them. Owners manual requires changing at
35 thousand miles. Mine has 120 thousand and runs perfect 

Alex Wonka says:

haha “my god, where are the spark plugs” my thoughts exactly when i popped
the hood of one of these jeeps. so glad there not on the sides like the
chevy’s they woulda been a bitch to get to

GraymanTactics says:

that grease can be used on any electrical connection.

Jorge Salazar says:

god tutorial ,,,thank you!

Actually , I changed my spark plugs at about 100 thousand miles , and the
truck was running pretty good before I changed them , its the unleaded gas
that lets them live longer , and they are available with platinum and other
exotic materials that have better durability .My old high compression
Mustang would go through a set ever 10,000 miles with high test Sunoco 260
gasoline to boot ..Now I have another hundred thousand so I,m thinking
Iridium plugs for the remainder of its life , couple years

Troy Thibodeaux says:

Thanks so much. I changed the plugs and got rid of a blinking engine light.
Changing out a coolant res must have splash water on a couple of plugs/coil
packs and it was causing a misfire according to the error codes. Running
better now and now no light and no error codes.

Not trying to start anything, just wanted people to know. Deathscouter,
good video. I take the reservoir off for the last one on the back left,
just because I don’t want to strip those threads by accident. And it’s
pretty quick and painless to do. Recommend you always use anti seize, I’ve
snapped an extension flush off at the socket on a really tight one. Not
fun, down in those countersunk holes!!!

Wilson Roman says:

I’ll give it a try tomorrow, I let you know. You explain in an easy way,
looks so simple.

Motomama88 says:

Thanks for posting this video. I changed my spark plugs today after
watching it. I only had 57K on mine but they were down to practically
nothing. My car was shuddering when I hit the gas so I was hoping it was
only the plugs. I do have to say that the back plug on the left was a
nightmare to get out. My car runs a lot better.

joebulls1 says:

does the 2010 liberty need anti seize

focusonthegreen says:

Great video, thanks for sharing. Congrats on the 160K miles.

betsy famiano says:

after watching this video I feel like i can do anthing. Thanks so much you
make changing spark plugs so easy.

sunilramkarran says:

go to the dealer and ask them to do a altenator output test and a heavy
load test

aijcadd says:

Very well done. The only thing I do differently is using a torque wrench to
do the final tightening of the plugs to 20ft/lbs. Like you said, you don’t
want to over torque them and strip them out.

BKofficer23 says:

Thank you for this.

UBBERTANKER says:

your suposed to change them every 30k not 160k because they come factory
with copper core plugs

millwrightman99 says:

Another quick point , I started using Dielectric grease on the inside of
the spark plug boot many years back when my plugs were always fused to the
boot and tear the wire apart when removing the plug from the boot .small
investment high pay-back .Plus it helps keep moisture at bay .

greatergreen says:

very informative video. Thank you.

mike schiffel says:

great video…just make sure that when you change the plugs that the engine
is “over night” cold !!!…otherwise removing the plugs might damage the
aluminum threads in the heads….ask me how I know.

Dylan Weisshaar says:

Yup! It is recommended for every vehicle to use. You can get it really
cheap so it isn’t to bad.

Lookeee_1 says:

Millwrightman, wondering about that dielectric grease….on a coil pack
would you still use that? Seems like it’s a whole different thing with
these compared to an old plug wire. Wondering how you would get that in the
tiny coilpack opening on these? Would be interesting to know if worthwhile.

tigerbalm says:

Wow, 160k? You should have changed @ 50k and very least 100k depending on
plugs!

Lookeee_1 says:

Although, these are relatively new vehicles, 1st yr 2002, so unless it’s a
diesel, the unleaded gas is a moot point. Not trying to start anything,
just want others to know what Jeep says to do. Might void your warranty,
you’d have to check. Many forums out there, do the research then decide for
yourself. These are really inexpensive-approx 3.50/piece or so, so even if
you change them every 30,000 you could possible still be saving money vs
the high priced ones, + gas mileage.

trucksroll01 says:

Great video, this was super helpful!

Stephen Knapik says:

Nice Job! You made simple and accurate

johnny vanderbeck says:

are the cylinder numbers the same on the 2004? I need to change the plugs
and the number 2 coil…. it`s throwing codes.

Mountain DG says:

Can bad spark plugs or low fluids cause anything like this? I’m an idiot
with cars and know I have never replaced or filled any fluids or ever given
a tune up or changed oil:( I’m a bad car owner but really need help or need
to know what to ask Pep Boys since I know they have not invested anytime
trying to find the problem. Thanks so very much.

Mountain DG says:

Hi. I’m a woman who knows so little about cars but I have taken my car to
Pep Boys and they had completely forgotten about it and they apologized and
said they would check it. It will start with a jump but then will not start
if left for several hours. The battery seems to drain in no time and it is
a new battery. Pep boys said they checked the starter, alternator and
battery and they are ok. NOw they just say they can’t help me. I asked if
electrical was checked but never got an answer

Lookeee_1 says:

@ Millwrightman- Ubbertanker is correct. Jeep specifically states on the
front of the engine and in the book that only ngk coppers should be used
and changed every 30,000. Course others have used different brands, and
many have used platinums, etc. However, if you go to any of the forums you
will see many people have had issues with going against what the
manufacturer says. I’m sure many haven’t either.
