What's the mercedes gl450 coolant type?

The Mercedes GL450 is recommended to use silicate organic acid technology. As with the other fluids in your car, engine coolant plays a big role in how your car is running and should be monitored consistently. It prevents your engine from overheating in hot weather and freezing in extreme cold weather, conditions where things can go very wrong for an engine.Without the coolant, the heat produced during constant internal combustion would ruin the engine very quickly. Although coolant is mixed with water, the water alone isnt able to keep the engine cool. The heat of the engine would eventually start boiling the water, or the summer heat would evaporate it.
