My '02 C32 has green coolant. I usually drain the radiator and refill it once a year rather doing a complete flush every two years. When I returned home from the dealership with a few gallons(part #q-1-03-0002) I noticed they were orange.

I read the green vs. orange in the MBCA Technical Library but gave no insight because it came with the green stuff from the factory.

Sut Ritter's aritcle gives a MBUSA part number of 000 98 08 25.

What should I do?
