Ok. Before I dive in I would like to confirm that a bad tensioner is actually what I'm hearing. What do the experts say?

Hard to tell with the engine noise until it gets worse. I could hear mine going bad from 20 feet away with the hood closed and it wasn't even that bad yet. It gave me plenty of warning. You can sometimes tell if it's starting to fail by a visual inspection. Do a search for 6.4 tensioner failure and find some images. They usually start to **** to one side and the gap will be uneven.

Yeah, it's a rumbling that kinda comes and goes. It's very pronounced when you're standing up close. But thanks for the tip on visual inspection, I'll do that.

Ok, going after the coolant pump, but I need to know the wrench size for the electric fan hub nut. Is it 47 or 48mm, and is it the same size as used on the 6.0 engines? I see wrench kits advertised for the 6.0 everywhere but none for the 6.4.

Please let me know if it works, because none of the rental tools I tried were the correct size. Finally ended up modifying a Cummins fan wrench and it worked great with a Phillips screwdriver in the pulley.
So I went in and replaced the A/C compressor belt and tensioner, both idlers, main drive belt and tensioner, and water pump. Neither both old idlers and tensioners, water pump, and A/C compressor appeared to have bad bearings, and the front engine cover showed no signs of cavitation - looked new inside, as did the old water pump. Haven't started it up yet, but I'm skeptical that the "bearing noise" will still be there. I really don't want to go in there again because I didn't install any zippers or quick connects.

Update: The F'n random grumbling noise is still there and now accompanied by an occasional loud metallic "chirp". Now I'm worried. What do bad rod bearings sound like on this engine?

As far as looking at the tool, it looks like it should work fine. I haven’t had to dig that deep since I did all my work. But it will come in handy next time.

Sorry about the noise. YouTube would be your friend trying to see if you can get the same noise.

Been to You Tube already. Scored zero. I would test fit your new wrench just to be sure.
