Some people do not see anything bad with it, as long as the type of coolant matches the one already in the system. However, according to experts, it is best not to mix different coolant colors - just for safety. For instance, there are some combinations that can completely ruin your car.

Without water, the additives will settle to the bottom of the cooling system. When this happens, the additives won't run through the cooling system as effectively and some parts may corrode as a result.
