Question for Hyundaitech, or anyone else who knows the answer....
How do you go about draining ALL of the coolant from an '06 Sonata? The owners manual and the online service manual say open the radiator drain, and let her rip. That gets you only a little over 2 quarts from a system that's supposed to be a little over 2 gallons. I wound up having to flush it multiple times with distilled water until no more green was left.
The answer to the first question to me is: Because the jug that has blue liquid in it, and says "removes bugs" doesn't go in that hole. This was after I was told the windshield washer didn't work even though it's full. Who knows how much made it into the cooling system, or if it would hurt anything - Methanol and aluminum don't play nice together, and who knows what the elevated temps would do - but there's none in there now.
