Coil Packs

[jeepdaddy65]

I'm going to change my spark plugs and was wondering, after I take off the nut on the coil pack does the coil pack just come off or does it clip on the plug like a regular set of wires, also should I disconnect the coils electrical connection or will I be able to leave it connected and move it to the side to get to the plugs. Thanks for any help

Just pull firmly on the coil, it'll come right off.

You don't have to disconnect the electrical connection. There's no real need to.

Hey im really embarassed to ask. I have never change a sparkplug before. The shop where im going to get my fluids changed is going to charge me for $75 just to change the spark plugs. Can i do it myself or is there some special tools or settings for that?
Thanks

A set of sockets (including a spark plug socket), assorted extensions and a universal joint is all you need.

It can be done in a little over an hour. Less if you're more experienced.

Don't actually yank on it though very bad things can happen. Pieces can get separated and fly away. Specifically I noticed this little spring that doesn't appear to be holding on very strong. Just pull firmly.

yea don't yank. also, I would disconnect the electrical connection on the top of the coil pack, just because when you go to pull it out, the connection may not be long enough. and the damn thing clips right in, its too easy not to just unclip.

to the guy who asked about doing it for the first time.

go slow, don't tighten anything past hand tight, and get plenty of dielectric grease and anti sieze going. you can do it with a basic set of tools, as long as it includes a spark plug socket

I should correct my post since everyone is taking it too seriously. I didn't actually MEAN YANK, i was just speaking in generalities.

Just pull it off firmly.

That better?

I know what you meant; however, we have some people here are inexperienced and I could see them going YANK, followed but "WTF was that" and/or "Where did that thing go"

Oh and don't confuse anti sieze with thread lock. Very bad too.

 

[offrovering]

good call.

thread lock, dielectric grease, anti sieze

ALL DIFFERENT

Did the plugs everything went smooth. I assume the previous owner never changed them, they were in really bad shape. I'm thinking that I should get better gas mileage now, although I didn't think it did to bad with the old plugs. Thanks for all the help and advice

Don't remember if JeepJeepster's how-to mentions this or not, but I found it easier to get to the passenger side inboard plug by removing the coolant reservoir. It's no big deal to do and makes getting at the plug with a little better angle. I also removed the air intake hose that connects to the throttle body...which will allow access to the throttle body itself for cleaning, while you're there .

Edit: Ooops, I see you already did it without problem. Good work...don't it feel good when a plan comes together?

Yeah it was pretty easy. I did remove the air intake, the throttle body looked good, I didn't remove the coolant resevoir, I just used a 3/8 universal and that worked out good
