According to the Lightning shop manual supplement I have, plugs are supposed to be torqued to 11 ft/lbs. I saw a couple of posts saying 16, perhaps a little too tight. I don't know, what do the tuners say?

i tightened mine to 13#.

 

I have the shop manual for the 2001 model year F150's. My book says 13ft/lbs. What manual do you have? I wonder if Ford changed torque specs? Maybe you could post a picture.

 

And, since you won't be able to get a torque wrench on some of them--NGK(I think) says "finger-tight(snug) plus 1/16th of a turn". Remember, there are only 4-5 threads holding the plugs in our aluminum head. Has anyone run a thread-chaser into the s/plug openings?

Here's where I got the 11 ft/lbs figure. When I ordered this manual they didn't have a 2K.

Thought a Ford Thunderbolt was a 64 Fairlane with a 427, dual 4 barrels and 425 HP.

Maybe, just maybe, with all the plugs being blown out they decided to tighten them up a couple of lbs. since 1999. LOL

 

Does anyone have the 2000-01 supplement?

Spark Plug manufacturers recommend "finger tight, plus an additional 1/16 turn" for taper seat, aluminum head application. That's what I have always done. I've never used a torque wrench on plugs, you never know when they are going to fail .

 

Mark, I've got two of the supplements, do you need one? If you do email me your add. and I'll send it our way.

SAL: You didn't read my post.....................did you? LOL Of course, it means more comin' from Sal, don't it?

On the supplement book........did you get it with the set of manuals or did you find it separate from the main set?

My set didn't come with one, and the lady I spoke to had no idea what I was talking about when I asked back when I got them for my 99.

 

I got it seperate from the manuals. I'll look through my receipts and see if I can find where I got it.
