Anyone know anything about Jeeps?

Rich J · September 4th, 2011, 03:03 AM

Well besides the stang, I have a 04 4.0L V6 Jeep Grand Cherokee that I acquired from my mom because she can hardly drive. Needless to say it gets TERRIBLE gas mileage so I am going to do a full tune up on it. Now most of my car knowledge is strictly Mustang so today I popped the hood and checked out what I was dealing with. First thing I want to do is change out the spark plugs because I have no idea when they were changed and I think it will help a good amount to change them.

Except... errr.... I can't find them? I tried looking for a coil pack (don't know if these are COP or not) and couldn't find any. So if anyone knows anything about these can you direct me to where they are? Any things I should take off too before I change them to make it go by smoother?

An 04 Grand Cherokee with a 4.0 should be a straight 6 not a V-6. The coil pack is on the passengers side of the engine and goes pretty much front the front to the back of the engine and is held on by 13 mm bolts if I remember right. It is black and has wires connected to it in the back.

^ Yep. Straight-6. Passenger side, it's a one piece coil. Runs almost like a very think fuel rail.
