Changed plugs on my V10

[samsontdog]

I finally had my plugs changed at 562 miles over 100,000. The Truck still ran great but it was past time. The gap on the plugs was nearly twice what it should have been. When do the rest of you change your plugs? The Truck is a 2003 Ford Super Cab with the V 10 eng

When changing plugs on the Hemi in a 2009+, be very careful of the A/C lines near the back passenger side coil pack. Don't touch them at all. The evaporator is very weak at the connection point and any bit of movement will crack it.

My mechanic pulled the plugs on my 09 Honda Odyssey with 158000 miles on them and reinstalled them. Said they looked great and no need to waste the money. It seemed we changed them a lot sooner when I was a kid, around 50000 miles, and they would look worn out.

The maintenance schedule on my wife's 2010 Jeep Liberty for plug changes is at 30,000 miles and wires at 60,000 miles. Thankfully, they are rather easy to change.

Her engine still uses copper. I would've liked to go with the 100k plugs, but from what I've read on the Jeep forums that engine just isn't designed to use those type of plugs.

Now, when my Hemi needs them, that's 16 plugs to change. That'll be fun.

I know. Still haven't lost one though.

Impact is what you need. The link I posted is an impact ratchet.

I remember the first one I did and I had heard all of the horror stories. I was trying to use a manual ratchet and spray lubricant. Slowly, but surely, they all came out, but took forever! Next one that came in, I said to heck with it. If they break, I'll still get paid to pull the broken piece. Grabbed my 3/8" impact gun and gave them hell. It was difficult to get three of the rear ones, but I managed. Didn't break any. As soon as I saw the Hammerhead, I bought it. Been using it since. Book time is around 2 hours and I can have them done in 30 minutes.

I have the 07 V-10 and my plugs are the ones that can break apart into 2 pieces when removing them, have to have a Leslie tool to extract the broken plugs if they break, someday I am going to have to get er done before I reach 50,000 miles and replace them with the newer 1 piece plug..

One of these and a 9/16" spark plug socket and you won't break a single plug.

Get a few different extensions to reach the sneaky ones.

I have yet to break a single plug when using this tool. About the only thing it does get used for. Proper torque when installing to keep the smell of gas on cold mornings is another issue.

I have seen videos on youtube people using the 3/8 air ratchet and removing the plugs when motor is warm and heard they never come apart but sometimes they do, I am talking about the 3 valve 06-08 plugs that were just spot welded on the bottom and they stick into the lower heads and that's why it comes apart, only these years have the problem.

I did mine at around 95K.

I bought a used 2000 Ford V-10 with 160k miles. I had new plugs and coils put on, milage went from 10 to 13.8 highway. Runs better as well, no stumble with hard acceleration. Old plugs looked good, mechanic thought they had been changed but said coil boots were bad.

V10 Plugs...took me less than 40 minutes to change mine. 10 min of that was fishing out an extension that fell...

V10 is a breeze...5.4 on a 97 F150...4 of them are easy...4 of them are a PITA...

Thanks!

Every pluged I ever pulled at or near the 100K mark was just like the OP said, Gap was way over the limit and some the electrode was noting but a nub! I'm with Dodge Guy and would never go past 100K, I you can do it yourself and you can't afford to pay to get it done then maybe you have bought the wrong vehicle.

Robertsunrus there is a little trick to getting to the back plugs, remove the inner wheel well and there they are. Same with a timing belt/chain water pump and everything else.

I think it was about 135000 miles on my '04 V10. It still ran good but it was time.

He probably knows it's a PITA to reach the back ones, so when he pulled the first one and thought it looked good he saved the effort of changing all the plugs.

No doubt about that one. Had a friend that says on the old Ford Aerostars mechanics would change the front 4 plugs and leave the back 2 untouched.

My 09 F-250 with a 6.8L says to change them at 80,000. I'm at 70k now so early next year they will get changed.

I do mine at 50k miles. Yes even the supposed 100k mile plugs. They are cheap and easy to do.

I don't know why people brag so much about going past 100k miles on plugs? (Not you OP).

🙂 Hi, if you are referring to me, the plugs on my Lincoln are very difficult to do with half of the engine under the firewall. And I don't want my heads ruined. So I will only have them changed when they act up. Plugs cheap, labor not! Easy to do, not on mine.
