Got a 2015 6.2. No where near time to change plugs, with alot accessories i have installed it would suck if the cab has to come off. Can the plugs be changed with the cab on?

 

Yes they can.

 

Why do you think the cab needs to come off? That's ridiculous

 

It looked impossible at quick glance

 

It's not very complicated at all.

 

Is everything normal or is it like the 5.4 and 6.8 headaches

Thank you for this . I have 122K and it's just about time to change them over the Holidays.

 

Haynes manual version:

1. Remove battery cable
2. Remove and replace spark plugs
3. Reconnect battery cable.

I would also consider a nickel based anti-seize compound on the threads. Any thoughts on this?

 

^ i think its a good idea, just a little tho

 

any name brand anti-seize. use very little. and do not get any on the electrode


I use aluminum or copper based
