Plugs...COP's.......
I have a 2003 F250 V-10 with about 48K miles on it. I am trying to do as much on my own that is possible to keep the truck running like a top. I feel she is running a little sluggish right now and have so far cleaned the MAF sensor (didn't look dirty) and will also check the fuel filter once hurricane Ernesto leaves. I would like to check the spark plugs, but have never worked on an engine with fuel injection. I like the old style with the plug boots staring right at you. Does anyone here have a picture, or a link of a picture that can show me the EXACT picture with instructions on where and how to remove the plugs?? Coil Over Plugs...... which are the COD's?? If I know that, I can find the plugs....... also, they look like they are attached to some sort of air line..........can anyone give me concise, step by step's to removing the plugs?? Thanks.

I just changed mine recently.The cod are just below the fuel rail.they are round and have a electrical connector.Push the release for the connector at the bottom and disconnect.Now pull up and out,now you will see the plug in the hole.I will try to find a post that might be helpful......

Heres the thread;

Just like to add having air to blow out the area and plug hole is invaluable.FWIW

heidiandmax, thanks for that link posting. I have a good idea now of what needs to be done. I do have an air compressor with a pinhole blower to clean out the plug area. I'll give the plugs a look today if the weather holds up.

before you touch the plugs change the fuel filter .the v10 dosn't like one thats even a little pluged up. and since we now have the alcieblend gas i have changed a lot of filters due to dirt and gum in the tanks.
if you do the plugs make sure you never sieze them and install with a torque wrench , "change the boots as a precaution", so you don't over tighten them and cause a blow out with a plug

I went under the truck and found the fuel filter. Being a holiday weekend, I am not even going to try to go pick up a new one. Looks like it needs a special tool to remove the lines. As for the spark plugs, they don't look so easy either. Hopefully, I will be able to remove the COP and the plugs without having to touch those injector lines. Never worked on an injected engine, so this is a first for me.

krewat has a thread posed on how to and you sure don't touch the injectors to do the job. takes about 3 hours total when you get going and have every thing lined up that you need .
good luck but it just not as hard as it looks .

This was my first plug change on my v10 myself.The only thing I removed was the hose from the throttle body to the air cleaner and the PCV valve/hose.The hardest plugs to reach are #4 & #5.The other 8 are a peice of cake..
Good luck to ya!

I removed the first COP and now see how they are setup. I took a look down into the spark plug "chamber" but didn't want to go further because I didn't have the replacement plugs with me. (more like exploratory research today) Now I also see why the need for the air compressor to blow out that chamber of any dirt that may have collected - before removing the spark plug. You know, a shop vac would work too....hemm... or a shop vac AND an air hose.
By looking at the other COP's and how they are sitting with that injector line right above it, I thought that line might have to be moved.... but after thinking about it, once I remove the brass screw securing the COP, it should wiggle out from under that line.
Okay, I see I have my work cut out for me this week............ Maybe tomorrow if the auto stores are open. Thanks for all of the info.
