I have to change my spark plugs 69K miles and I'm going to test out the Impact Wrench method for changing them. Has anyone else tried this?

"Quintin - Lukewarm engine, loosen plugs a quarter turn or so, spray carb cleaner in the plug wells and let them sit for 10-15 minutes. I use a fresh battery in my Snap-on 3/8" cordless impact, and go. Hammer on them and don't stop until they come out."

This method makes the most sense to me as I think an impact wrench would shock them loose. I'm going to try to change them this week using the above instructions.

Question - Does anyone in the Pittsburgh, Pa area have a broken spark plug extraction tool that I could borrow if I do break one or all of the? ha ha Or would anyone be willing to send one to me to borrow?

Please PM me - thank you

 

Im going to remove mine this way also when it warms up here. I'll be following this post very closely. Be sure to post pics and let use know how it goes. Also post any little tips or observations you learned while doing them.
Good luck bro.
May the force be with you!

 

I'd be wondering what kind of impact he uses. I have three of them in 1/2", with all very different power bands. I'd guess one of the smaller guys on a lower power level could be the ticket.

 

3/8 in, rechargeable.... Not the Gorilla model either. You don't want to RIP it out of the head. If it's TOO powerful, it's no different than using an air impact- heck, if power was the issue, you could just use a 1in. air impact and the head would come off with the plugs!

 

I was planning on using my 18v Battery Powered Dewalt Electric impact driver and if that didn't work, I have a Dewalt electric 1/2 impact wrench. Then move up to the 3/8 air ratchet with low air pressure.

I'll be using this - what I have

I'm thinking I don't really want to remove them fast- but I want to impact the hell out of them in the process to break that lower part free.

 

I am planning on doing it this way in the next month or two. I am at 58000 now on the truck. I have read up on Quintin's method a few times and it seems to make better sense to me. But to be honest I will feel a little better if a couple of yall try it out first! Be sure to post results!

 

Just remember, heat expands cold shrinks. The hotter the head is the threads get tighter not looser. While this would also thin/soften any grease/oil/carbon, I would really give this some thought.

 

I might have to try this way as well. But I'm to scared to be one of the first.

 

There has been at least one other member other than Quintin, so not the first. I suspect a lot of techs use this method. You go to a dealership and they have it done in 2 hours. How can an engine cool down and them take all the time to soak and back off on each plug? I suspect a lot use their cordless impact.

 

If your going to break a plug, you might as well do it the fun way - right. A lot on here broke plugs following the Ford TSB. Isn't the TSB written by the same people that "Engineered" the problem to begin with?

Screw the TSB - I'll follow the QSB (Quintin Service Bulletin)

 

ROFL

 

The way i figure is if there going to break they will. It does not matter which method you use, if it going to break it will. The slow screeching method is long and nerve racking. Treat it like a band aid. Rip em out quick and get it over with.

 

My 06 needs a plug change also, I'm just scared to take it to the dealer because they will probly charge me $500 and up.
