V10 Excursion Spark Plug change

[eldogo]

How much of a pain is it to change spark plugs on a '04 Excursion with the V10? How long should it take me? I'm a comptent mechanic but it's been below 20deg the last few days and I'm wondering if its worth the $ to have the Dealership do it?

Their not to bad with the right tools. you need a 1/4 drive 7mm wiggle socket and long extention to remove the coils. A swivel spark plug socket and 2 swivel adapters to reach the back spark plugs. I recommend replacing the rubber coil boots while your at it. I also recommend only using motorcraft parts. Im a dealer mechanic and the dealer I work for charges 4.5hrs for a V10 tune up. So parts and labor your looking at over 500.

Couple of things:
1. Make sure you blow the plug holes out after you take the COP's off, you'll be amazed at how much trash is in there.
2. Soak the plugs with some type of lubricant after blowing them out.
3. Since you still have the 2V motor, make sure you get the correct torque specs and USE A TORQUE WRENCH!!!!
4. Before installing the plugs, put a little bit of anti-sieze on the threads to make it easier next time.
I would think you should spend about 2.5 to 3 hours on it, the back two are the worst ones.

Like the last post said...be exact on the torque specs when putting the plugs in. Call ford or look around to find the right torque. I don't remember what it is. You don't want those plugs to blow out

I had the dealership do my expedition back in the day at 100k. When I did it again by someone else at 200k they shown me the back 2 had never been replaced.
