    Hi, I have a question: my old coolant is a light blue color and I have a 2004 Ram 5.7 Hemi, but a friends of mine (with similar model) has red coolant!
    So, I can use a new blue coolant again or it's necessary a sostitution?
    Thanks and sorry for my english...

    Yours is supposed to be an orange color (HOAT) but it sounds like something else was substituted at some point. What you definitely don't want to do is mix incompatible coolants (bad jujus).

    Hi and Thanks for the answer.
    In fact I wonder if my fault is wrong ... at this point I should continue to use the same color of coolant or I do a good washing, then unload, then again washing and then unloading and finally do I put on orange coolant?

    For Ram I bought it used about 4 years ago and since then I circulated with this liquid (blue) without ever having any problems...But now I have decided to replace old coolant!

    I need to be able to understand you before I can offer any advise bud, are you talking about the engine coolant? If so then flush it out and replace it with HOAT antifreeze.

    Yep, Zerex G05. I used to think it didn't make a difference but I'll never use anything else again.
