From my experience, if it's squeeking, the tensioner is the culprit.

I swapped belts on my 7.3, instead of the tensioner, and the tensioner soon crapped the bed, shredded the new belt, ripped the AC wiring apart (wrecking the pump), and other bad things.



I think the 6.4 has 2 belt systems, yay

thanks parkland. I have watched every video i could find and read alot of directions by guys that know a heck of a lot more than me about this. Im going to tackle this thing tomorrow. the dealer wants 350.oo just to replace the pulley and belt. whew!! one set of direrctions say to remove fan shroud and fan to replace belt. the tensioner seems a little easier to replace from underneath.

I'm almost certain somewhere here a guy did it, and did it from underneath.

I just take it to the dealer to get worked on now, every time I try to do something myself, I feel out of place; I'm too tall and big to get my hands in anywhere, I can't wait to start deleting engine bay components

I agree it's most likely the tensioner but while I was in there I would be sure to replace both belts as well. Also be aware there are 2 tensioners so you might want both on hand in case they're both screwed. Also be certain this isn't covered under any existing warranty you might have. Mine went bad about 8 months ago and it was covered. I just paid for the new belts and the dealer took care of the rest. Good luck.

Tensioner is covered under the 5/100K and they will also cover the belt if it ruined it, it has if it is squealing.

If under warranty I would take it in. They need to hear it to replace it. Belt will also be replaced...due to the tensor issue.

They should not charge you for the belt.

Two belts, two tensioners, near zero access, yea-fun

The docs indicate to remove the radiator shroud and then work through the larger gaps in the unevenly spaced fan blades.

I wonder why we even have 2 belt systems?

Plus there is an electric pump for the 2nd cooling system.....


Time to start yarding stuff out, lol.

I have the absolute worst dealer for not covering "questionable" items and had no issues with it being covered, need to try another dealer or another service adviser, or a higher up. Your 5 years may be up though depending on the purchase date.

There is a reason why just replacing the belt is over $300, it is nasty to get to.

The defective part is what determines the warranty. If he looks it up in the puter he will see.

No deductable and all other items covered.

im going to call another dealer today and push the oasis issue. These trucks are crazy priced and they need to warranty the issues that they say they will when you buy it.

You know what would be a good sales pitch?

Free 100,000 mile service:

New engine coolant
Trans flush
New axle fluid
New belts
etc....

Just had the tensioner and both belts replaced. $250 in parts. Total repair bill?... $1,180.
They claim the labour is a result of having to remove all 5 rads to get at the front of the block. I can see that, but still... jeez.
