I’m buying a 96 Dodge Ram Cummins, which has good service records. It currently has “green” coolant in it. While I’ll know when it was done last, no guarantees on what it was.
System looks great, coolant is clean, but again I’m not entirely sure what it is.
I currently keep G-05, G-48, JD Cool-Gard II, Honda premix, and some Dex cool. Dex goes in my Chevy truck, G-48 in my 135i. I’m not inclined to run either of those. Doubt Honda is the right stuff for a fully iron diesel.
G-05 is a well known quantity that I run in my iron MB diesels. JD is good stuff and I’d be confident running it.
I don’t know if the green in there is something like the Zerex traditional silicated green, or something like prestone all makes with cor guard. Due to the unknowns Id do a couple drain and refills with distilled water, just driving enough to warm the engine and mix fluids. Then I’d introduce the new coolant.
So what should I run?
