Do car radiators need frequent water refills?

[DiAnastasia]

If the radiator isn't leaking, you may not need to add water all year, but regular checks are necessary. Here are relevant details: 1. Antifreeze: What you add to a car radiator isn't tap water or purified water, but automotive antifreeze. In emergency situations when antifreeze isn't available, small amounts of purified water can be added temporarily - but only minimal quantities, otherwise serious consequences may occur. 2. No mixing: During winter, automotive antifreeze must be used, and it must be the same brand. Different antifreeze brands may contain different components, and mixing them could lead to other problems.
