The salts, chlorides, and metals that are in your tap water will definitely do some damage to your radiator,seals, hoses etc.

Make sure it is RO/DI water(which they don't sell too often at the supermarket anymore)/ Don't use "RO water", "purified water", "distilled" water or bottled drinking water. It has to be RO/DI water-there's a difference.

Go to a saltwater fish store with a 5 gallon bucket, they make and sell RO/DI water. It costs <$2.00 to fill a 5 gallon container.
