Hi MB gurus -

Just a quick question. My father, trying to be a good samritan, took our `90 500SL into Sears (gasp) for a coolant change. They put the green crap in it. So, when I got the car back, I scheduled a coolant flush and change at my local MB dealership. The car happened to be coming up on its 45K service, so I had it all done at the same time. However, when I got the car back, it still looks like green crap in the reservoir! Does anyone know what color is the actual Mercedes coolant (which I understand is formulated for their aluminum radiators)? Any other easy way to tell if they actually changed it out? They signed my book and everything, but I'm still suspicious...

TIA,
