i have a 2008 f250 with the 5.4l engine it has 72000 mile getting ready to change spark plugs i'm aware of the special socket. what should i be careful of? is breakage still a concern? thanks for help

As always you do want to take care with the plugs and then when you put in the new ones use an anti-seize compound on the threads.

Crack the plugs loose then put a little decorbonizing fluid on top let sit ouer night then try you can also use a little diesel fuel. Ive worked on several vehicles that people have broken the plugs off, then it becomes a real nasty job requiring special tools.

I was informed that you don't put the anti-freeze on the threads, just the "sleeve". And what about doing it in cold weather as opposed to the recommended "room tempature" (70*)???

Also, what special socket are you referring to? More than a normal spark plug socket?

 

[Mr Mac]

For the Ford a thin walled spark plug socket is called for, not the normal spark plug socket we all bought for our older cars/trucks.

Here is Autolite's version of the job and I like their approach;
