What coolant do you use?
Does it matter the type or is it more important to change it regularly?
Do you use a SCA additive?
Anyone ever see cavitation erosion in these motors?

yes it does matter,
I just changed the coolant in my 05 model

I used: Napa Zerex G-05, that is an approved coolant for the dogde diesel, it has the HOAT additive that Dodge requires.

of course mopar coolant meet the specs, but also understand that ford makes a coolant that meets the specs.

I used the Napa Zerex G-05, 3 gals and 3 gals of distilled water and a new thermostat.
the napa coolant was less expensive than others, about $18 per gal

should be good to go for a few years.
