sorry to raise an old thread. I'm planning a coolant flush on my Ram. I changed the coolant once before and used Mopar Coolant.
Of course considering that we often look at the best fluids in terms of engine oil, I'm thinking of using a good Coolant like Valvoline's Zerex.
However I cannot find out which one I'm supposed to use. I know that my brother's 2004 Durango needed HOAT type and it was orange in color. I'm wondering if the Ram needs the same. Or do I need OAT.
Which one do I choose?

Are there any other recommendations other than Zerex?
