Has anyone changed the plugs or had the plugs changed on a V10 in a van? How hard/long of a job was it, or how much did it cost to have it done? Our E-350 with V10 needs plugs and at least one coil pack, and I'm wondering whether we should try to do it ourselves or just cough up to have the dealer or a shop do it.
Thanks,
Isaac

I've heard people say that it ran them $300 or so for just plugs. I haven't done mine yet so I can't say how hard it is but I sure as hell am not paying $300+ for a plug change.
Keep the plugs and get the single coil on plug replaced. An independant can change the coil plug for about $200 (pull the code for the coil, pull the coil, verify the coil, replace the coil). Dealer in my area wanted $175 just to tell me what I already knew, a coil was bad. I've got 95K, same set of plugs, 2 coils so far.

My 98 E-350 V-10 is at 95K miles, so I'm just about ready for this change too. I know the pick-up guys complain about one plug in particular in the back, but we vanners should not have that particular problem. I can't imagine paying more than $5 each for plugs, and some people say to replace the boots also, which can't be too expensive. The single MOST important thing is to make SURE to get the new plugs torque'd properly, and that you use some thread lube on your new plugs. The V-10 has very few threads in the spark plug holes, so proper torque is mandatory. The thread lube just helps prevent galling between the steel plugs, and the aluminum heads. Some dielectric grease on the boots will help prevent misfire in the future. There is one plug on the V-10 that sits right over a coolant connection. If you have a small leak over that plug it can erode the metal around the plug and cause spark plug blow out. But I'm going to change my own plugs. The doghouse coming off has got to make it much easier than opening a hood. But I went through a major headache after putting plugs in a Zetec Ford. Unbeknownst to me I was cracking the insulators, which would cause a misfire in a couple days, it drove me and the dealership crazy until we figured out what it was. The torque amount is critical. Make sure you have a plug wrench with the neoprene protector, and go slowly and carefully when you're fishing the new plugs down into the hole. You can do it ! (when you're done, post here so I can do mine) Take care, good luck, Ken
Yeah, we'll probably have a local shop do the coil but I think my dad and I will probably tackle the plugs ourselves one of these days...the van has 144K miles on it and I don't know whether they've ever been changed or not - we bought it at 137K.

It's not as bad as it looks.
Start by removing the front seats. it makes getting into the engine way easier.
They only take 5 minutes to remove.
Take a look at http://www.ford-trucks.com/forums/sh...d.php?t=104027
It's not exactly the same but pretty close.

Sweet post that you linked to, thanks. I have been pretty intimidated, but it appears that it's just like any other plug change, just a bit different. I'm looking at my doghouse, and it's looking like I should be able to get to most of the plugs on my V-10. But my-oh-my, if I have to try and get to some of the plugs from the front, with the 16 inch hood opening, and all the rest the doodads that the vans have poking out the front,,,,I just can't say anything else that would be considered polite conversation,,,, But your link to your post was awesome, my thanks ! Ken
Wow, great thread! I had to tell my wife that I did'nt know where the plugs were located on my E-150 4.6L van. I'm no slouch at mechanical stuff but I hav not kept up with the new vehicles and their systems. After reading these threads I think I can do this. With the help of forums like this we can survive. Thanks everyone for sharing the info. When I changed the ball joints last month I wrote up my experience at the van forum hoping someone else can benefit from it. At 60000 miles I have experience a 4-5 mpg decrease in gas mileage over a 2000 mile trip. I am wondering if a plug change will help. I have also noticed the tailpipe looks a little blacker than normal. Running rich? There are no service lights coming on. Is it worth changing the plugs out?
Sometimes on startup after sitting for a couple of days the engine runs rough for about 10-20 seconds and then clears up. Like it was loaded up or starving for fuel? I have not noticed any sevice lights but I will have to pay more attention the next time it happens
Thanks,
Rick

The rough running seems to be common to the mod motors. There's a forum discussion in the V-10 section, look it up there. There are also 4.6 and 5.4 owners who are having the same problem. There's a couple different theories as to what it's worth. Ken
