06-08 engine bay reservoirs - coolant and washer

[Rogan]

I've seen a few 3G trucks with coolant bottle in the RR of the bay (pass side firewall) and washer fluid in the LF.   My 07.5 has the combo bottle in the LF.   What denotes the other (separated design) layout vs the combination tank?

 

I ask, because I'd like to separate mine, due to some PTO pump clearances I'm looking to add.

If one of you know what particular denotation the separated tanks are (or hell, even PNs), I'd greatly appreciate it.   I'm looking to go this separated tank layout.

It depends on the MY and engine. The 07.5 is a 6.7L and the photo you posted is a 5.9L. There was also a slight difference, from what I recall, on the 03-04 5.9's vs the 04.5-07's.

Correct, and I'm aware it was a 5.9 pic.  But I was unsure if the bays are really any different.  I know the 6.7 turbo is alot lower and further back, too.  But wasn't sure if the bottles would interchange, that's all.

 

I appreciate your input, as always.

The 5.9 and 6.7 in 2007 have lots in common with their cooling systems, aside from the routing of the water cooled turbo. 

 

I would look at your setup and see how the overflow bottle is plumbed into it. You might also want to look at a early 4th gen, as they were split tanks and still ran a radiator cap. There isn't a radiator cap on the later 4th gens, so the bottle will be different there too.
