How to replace spark plugs 3.6. Please

 

Same as any other vehicle. Unscrew the old ones, screw in the new ones. What specifically is your issue that you need to ask how to change spark plugs?

 

I have never done a plug change on the DJ 3.6
but I would suggest it is a little more complicated
with the rear plugs being located where they are
in relation to the intake manifold.

 

We'll in surfing web some are saying the plugs by the fire wall will be hard to get to. And yes I have screwed and unscrewed plugs, But never on a dodge journey 2013 3.6 lvvt. This is why I'm asking if there is a easy way to get to the plugs by firewall or any tricks.

 

Skinny arms would help from what I've heard. Why are you changing them?

 

Anytime someone makes an instructional video and
starts off using a sawzall is when I realize the reasoning
behind my decision to let the dealership do it when needed.
Little money for having it done by people with the knowledge and tools.

 

Dealer said #3 plug needs to be replace, That Dodge claims there's a problem with Dodge journey 3.6 but out of warranty

 

Chrysler/Dodge did have a problem with the left cylinder head
on a limited number of the 3.6 Pentastars in 2011 models.
Having said that have extended the claim warranty period
to 10 years, I know this is a fact as I have the letter in my
DJ should the problem arise.

 

I would suggest that rather than a spark plug problem you have a left side cylinder head problem which should be covered by Chrysler warranty.
Had same issue with 2011 Dodge Journey.
Take it back and have them test for left side cylinder head problem - well known to all Dodge dealers
