Hi,
I have purchased 40/60 ready-mixed Volvo Penta green coolant. The package says it's freeze point is -13F. However, since I have a closed cooling type of engine I'm now wondering if it's good to leave it in during the winter since temperatures in my area can go as low as -30F (rarely, but still). So now I'm wondering - does freezing mean it will probably burst something or it means it will start to form crystals or become gel-like or what it means?
