2007 Honda Element coolant, which one to use green, emerald green or blue? - 1

Use Honda genuine coolant. It's not much more expensive.

Read your manual. If you don't have your manual or you can't read, the guy behind the counter at the auto parts store can look it up for you.

You shouldn't need to add coolant. If you're changing the coolant drain the system and then go to Advance Auto and buy their ALL compatible antifreeze and use that.
