It's about time to change the coolant in my suburban. Typically I would flush out the dex and refill with green. They seem to have the plumbing more messed up on the new ones and I'm not sure I can get all the dex out with 1 shot. It only has 45K. So I could just drain and refresh with dex.
I heard the new dex is not as bad as the old but not sure.
It should I flush and not worry about some mixing?
Thanks for your thoughts.
