how big of a job is it to change the belts on the 6.4s? if it is gonna be a hassel i may let ford do it since i dont have a lot of extra time. thanks for the input guys

It sucks to do the ac belt. The main belt isn't too bad.

will i have to strip a bunch of stuff off or can it be done with everything in place

main belt is pretty straightforward you dont have to remove anything just come in from the bottom. The A/C belt it a whole different story atleast on my truck with dual alternators I had to remove the main tensioner and then remove the bolts from the fan shroud I installed a new tensioner while I was there and it was a pain to get to move due to lack of room and being such a stiff spring and the belt has to fit behind the cast mount

do you have to put the ac belt on first then the main belt? my truck doesnt have dual alternators. i may try this tomorrow. i may go ahead and do my tensioner also.

did you replace both tensioners when you did it?

I still need to do my a/c belt, looks like a chore.

Which belt/pulley squeaks on 6.4s the idler and main?

JuststrokeIT · Apr 10, 2013

I replaced both tensioners as their known to have issues just for piece of mind, as well as the top idler pulley because it was bad. And correct you do the A/C one first as it sits directly behind the main belt so that you cant remove or install it without the front one off first

It can be done but like the others said, its a pain to get the a/c belt off and the new one back on with the small amount of room in there. I would also replace both tensioners and the pulley up top as well. My truck had just under 60k and they were all smoked pretty much.
