Ignition Coil

[inyati13]

I replaced an ignition coil on a F-350 2004 5.4 Triton.

I bought the coil at NAPA. The original coil had a rubber boot that was angled so it would seat in the spark plug well. The replacement coil was straight. Now I know why they are angled. It was very difficult to get the set screw in and then attach the ignition plug.

Question: some of the coils are more difficult to access. Should I get original Motorcraft ignition coils in the event one of the rear coils goes bad? I cannot see how the straight replacement coil could be installed in the rear cylinders.

You can buy replacement boots from motorcraft or use the old boot.

I went online to Amazon and bought eight new Accel coil packs for my ford delivered to my front door for what ford wanted for one coil pack, and my ford will get up and go with the best of them.

Coils are coils IMO i buy all mine off ebay and they work great truth be told they make them for motorcraft. If there bought for that truck all coils and boots should be angled I hope you put dielectric grease on the boot that goes over the plug

All comments above are helpful.

Sky. I got it at NAPA. It was not angled like the original equipment. I gave the guy the details on the vehicle and engine. He spent time looking it up so should have been correct. I have dielectric grease but did not use it. Should I remove the coil and put some on? Should grease go on both inside and outside of boot?

Just a little dab on the inside where the spring hits the plug
For those that think a coils a coil haven't wrestled with a late model Nissan who's computer control can detect the "difference" and will not turn off the check engine light until a proper coil is installed.......

King in relation to his ford the fords aren't that sensitive but my wifes infiniti suv if you put any after market part on it you ask for issues and light will NOT turn off. Infiiniti has Nissan motors etc King great point you brought up.

Thanks to all. The check engine light is not ON. So accepted the coil and is not misfiring. I am going to remove it again (dam that is painful) and put a dab of dielectric grease on the spring that goes over the plug.

Ron taking the coil packs off is easy compared to fighting that back plug on the passenger side

I had the plugs changed not long ago. I can imagine how hard that would be. The original coil has an angle to the boot was not bad getting out. When I inserted the straight coil, it would not line up with the retainer screw hole. I am going to put the old boot on this coil as was mentioned above. I didn't know the rubber boots could be switched out.

There is like a lil portion on the coil pack that's like on the side for the curved boot to fit in I have tons at home I change them all the time I can show you what I mean later...I am wondering if you got the right part for your year you know sometimes factories put wrong stuff in the box. When I change the plugs to make it easy I take the fuel rails off and move them out the way

I know what you mean about the boot. I actually pulled one off to expose the spring and the metal rod in the middle of the spring. I guess I am getting senile. I should have thought about switching them out. BTW: I finally got the hole lined up but it did occur to me that the coil pack might not be right. The ignition plug receptacle is pointed upward. It is on the side of the original coil. So something is not right.

I would take it back because I think you got the wrong part.

I agree. Obviously it works but I think we should nudge OCD Ron back to "Napa No how" just for grins...:)

Going to take the old one in and see if they have one like it. Thanks. Big help.

 

[inyati13]

Got the correct one. Will replace the wrong with the right one tomorrow. Should go smooth. Thanks again. Last time I worked on a car, they had plug wires.

 

[skyhightree1]

Yea I didn't think you had the right one

 

[inyati13]

Yea I didn't think you had the right one

Bottom: wrong one
Middle: right one
Top: original

Notice how the ignition plug receptacle is angled on the wrong one. Amazing but it worked fine.

PS: WENT IN EASY

I have changed enough of them to know how they are supposed to go and such :(
