I've found something I just have to ask about. Mercedes has in their service recommendation a coolant change interval of 15 years/150,000 miles using their (water/MB 325.0 anti-corrosion/antifreeze mixture). Is this because the engine is aluminum and (not sure) the radiator also? Because of our Iron horses in the vetts would this MB325 be useless in our cars?
