Gents,

My 2001 supercrew needs new ignition coils. Yes, my mechanic (a personal friend so I trust him) says to replace all eight. The truck has 130,000 miles, so it is probably better to do all at once anyway. I got the set of 8 coils for a great price, so it didnt hurt so bad.
I just found out my mechanic is going out of town for two weeks with his family, so I am going to do this job myself. All I need to know is what items need to be removed (other than the bad coils and plugs) for me to get this job done.

Any help is appreciated.

thanks.

 

theyre pretty easy its supposed to be a a few hour job. you just need to take the bolt that hold the coil unplugg the electrical plug. pop them out and while you do it u should change the plugs and i recommend the dual prong not the split single. u shouldnt need to take off the fuel rail i wouldnt touch it at at all the injector seals i heard nead vaselean or a lubewhen put on . i just cleaned my coil wires and cleaned them just for the heck of it and put some electrical conductive gel. !!!!!!! WHEN OR IF U CHANGE YOUR PLUGS DO IT WITH A COLD ENGINE!!!!!!! and i would take a air hose and blow out the plug holes i have a 2000 5.4l that is what you have ?? same set up ish?

 

yeah, i have the same set-up. i am going to attempt to change them today, just letting the engine cool down from work this morning. thanks!

 

Am sure you can handle to job if the proper tools are available. Have a question, why did your friend (mechanic) advise you to change them out? CEL or what?

 

the back 2 closest to the firewall on the drivers side are a pain in the dick to change, but other than that, they are pretty smooth changing (
oval shaped with flat glossy top). i think the bolt that holds them in is (8 mm?) and the electrical harness. all you have to do is squirt a lil dielectric grease on the connections before you reinstall them. you do not have to take the fuel rail off to change them out, and like the person said earlier, i would recommend changing your plugs and wire connectors since you are pulling your spark coils. all n all, simple task, just a little time consuming. have fun!

 

Its a 7mm bolt head. The new coils might come with spark plug connectors (th rubber boot between the coil and connector) if not get a set of new ones. If an injector is in the way you can carefully turn it. I have never had to pull a fuel rail yet to change them. Make sure the bolt is straight when you go back in or it will strip.

 

I knew it! Already having to replace Ford parts because they don't last. It must really suck knowing you have to do so many repairs so often.

 

running the same coils and plugs for 130,000 is just stupid, routine maintenance is to be expected...those who dont understand it are always the first to complain about spending money on parts. stuff wears out, deal with it..its not a ford or chevy issue, although you probably want it to be just so you can justify your purchase, Chevrolets OEM manufacturers arent any better or worse than anyone elses.

 

Your right... sorry I didn't mean to offend you.

 

not sure if i understood this all the way but if i did get it right you want him to blow out the plug wholes into the head? with them on?

thats a good idea, almost as good as putting thumb tacks in your upholstery.
