Yikes, I didn't mean to start a 'war'.
I am about an hour+ away from a dealer (or Hopefung), and it's a very busy week (hard to come up with 2+hrs to go and get it). I phoned around to some places closer to me, but so far no one carries the MB stuff. That's why I asked about other possibilities. I don't exactly need it 'yesterday', but we did lose some coolant during the valve adjustment. Not sure how much. It's running okay, but the temp did get up to 90 yesterday. Usually it stays at 80.
Oh well, we'll figure something out. Is the MB stuff premixed? I got a quote of $15/gal, and we were thinking it would take 3 to completely change the system. But if it's not mixed yet, I'd only need half that.
Thanks!
