    So, I have a 2011 2.7L 4-cyl and I can't locate the spark plugs anywhere, I have looked in every nook and crany visible from the hood and from underneath and every which way! I'm not having any luck searching online or in the manual so I hope that you guys can help. There is of course no distributer because it's all computerized so no hope of following the wires. I don't need to change them just yet and probably not for some time, but I would like to know where they are and if it is at all practically possible to change them myself when the time comes. Thanks in advance!

    They go right thru the top of the valve cover, in the center. The Air intake is blocking them.

    Hahahaha! Well... don't I feel dumb. :eek: At risk of making myself look even more foolish I must ask, is it absurdly difficult to get to them? How is it done?

    My question would be: Why do you want to replace them?

    Its one of the easiest vehicles to change plugs on. All you have to do is remove the intake assembly, remove 1 bolt holding the coil on the plugs, disconnect the harness, and remove and replace the plug :) No need to feel "dumb", as we all are new at one point or another.

    Well, the truck has alot of sentimental value to me and I plan to keep it to the day I die if at all possible. I am in it for the long haul. At some point in time they are gonna have to be changed right? Standard procedure from what I understand. I am also the kind of guy who likes to do things myself, for example, I have quite a few free oil changes from the dealership... never used one. I like to do it myself so I can be 110% certain that it has been done right. I have heard many stories of people marking their oil filters in a subtle way to find after an oil change that the filter was untouched! I am aware of at least one account of an anonymous well known company accepting payment and releasing a vehicle with no oil in it at all! I am sure they would make it right but I'd just as soon avoid any chances of this happening in the first place. But I guess I'm getting a little off topic as I have been known to do. Anyways, yeah... Why? Because eventually I'll have to.

    That is very good to hear! thank you! Man, I was just looking at a couple of old fords, 1976 F-150 and a 1996 F-150. Both were very simple and easy to work on. I have replaced plugs and done various light mechanical jobs to both and I could look at parts under the hood and tell you what each and every one was and what it was for, not the case unfortunately with my new truck. All sorts of little wires and tubes and such, good lord! Anyways, thanks for the good news! I appreciate it!

    Only thing you need to be carefull of, is over torquing the new plugs when putting them in. Use a torque wrench. Aluminum heads are easy to strip the threads in. Also, do the change when the vehicle is cold. I prefer to change them first thing in the AM after it sat over night.

    Repeated for emphasis.

    Heat things up and they expand.
    Everything expands, including the space between things heated... meaning that when hot, the spark plugs "loosen"... Worse with aluminum heads because the aluminum expands more than the steel plugs.

    So change plugs on a hot engine and they will come out REEEEL easy.
    Install new ones... new COLD plugs.... When the engine cools down, the head will lock onto the new plugs like Chris on Candy Samples' nipple.

    Next time you remove the plugs, the threads will come out with the plugs and you're going to have a very bad weekend.

    Fortunately, I discovered this on a '76 Chevy LUV and the head was warped and kept blowing gaskets anyways so we were expecting to replace the head. Buddy was still not happy, but he calmed down when I let him use my Camaro for his date that night :D
