I'm changing plugs on my 04 screw. 90k miles not sure if they are original or not.. (bought the truck with 68k)


what method is everyone using


impact


slowly working it out with a socket wrench

 

I know what my way is but everyone is different and it depends what yer comfortable with....imo

 

and what's your way?


I could see how both ways would work.... and I think it's more of if the plug is Ganna break it's Ganna break with either method


just trying so see who is doing what

 

I had Patrick to do mine (patman) and he used the impact and all 8 came out easily.. He has a thread somewhere.. I will see if i can find it

I think running a couple of cans of Techron through may be more important than the removal method.

 

only had a handful break out of a few thousand that I've changed using the techron/impact way....

 

I believe either way will work, but I used 2 bottles of techron on two half-tanks of gas and then penetrating oil in the plug wells allowed to sit for an hour or so. Then I just used a regular socket wrench; had some squeaking but not even the hint of breakage. My plugs looked just fine with 60K on them.

 

IV only got a 1/2 air impact... can I use that? should I turn down the air pressure or let it zing it off

 

A buddy and me used a cordless impact on both our trucks. All 16 plugs came out fine. We tuned the torque donw to about 60 ft lbs.

If you can turn the torque down on the air impact it would probably work fine but the bigger issue will be getting the gun to the plugs closest to the firewall. It is a tight squeeze.

 

Did mine a couple weeks back, 90 thousand miles on original plugs. I ran two bottles of cleaner through the gas. Truck only had half tank each time. I read a bunch of threads and watched videos on YouTube. No matter which way you do it, you might break a few, all of them, or get lucky and get all 8 out. I used hand tools and took my time. Night before I loosened all 8 a 1/4 turn, then let them soak with aerokroil until the next day. When I started on a plug I tightened it back up and began working it back and forth a 1/4 turn each way. They will scretch coming. The key is patience. I got all but one out, which I used the lisle tool to get the end out. Each to their own way, but it was a pain in the azz. I wasn't paying a local guy 500+ to do it either.

 

I was going to do mine but a Friend is a Service Writer @ My Dealer They charge a Flat $259.95 Break or not,All mine came out for that price I just couldn't justify mesing with it & buying tools & such,They got all 8 out without any breakage I am sure when you do these plugs every day you learn a few tricks.

 

I would have easily paid that but wasn't that lucky, another local shop that works on mustangs and other high performance cars said 300 but said he was to busy.

 

did them yesterday

tried impact and wrench with no luck with either

broke 7

and the porcilin didnt come out of 6 of those

the drivers side rear plug gave me the most trouble getting out

 

You get them fixed? Did u leave them soak at all?

 

I was told by my service writer that factory plugs have a paint splotch on top of the part that the COP connector attaches to. He pointed that out to me on one of my old plugs after I had them changed out a few weeks ago.
