Distilled Vs Deionized Water Coolant

At the very least all you need is distilled water.
Distilled vs deionized water coolant. Antifreeze coolants also cause corrosion but modern versions of the product have been infused with rust inhibitors. To be classified as purified water it must contain 10 parts per million ppm of total dissolved solids or less. Deionized water can pick up other ions in your loop from other metals and cause possible corrosion rust to occur. I always go with distilled water though.
Distillation is one of the oldest methods for creating pure water. As it chemically removes electrons from the metals of cooling system components distilled water eventually does extreme damage that could lead to cooling system failure. For flush it s not staying in your system for very long so it shouldn t be a huge issue. For flush it s probably fine.
You don t generally want to substitute one type of water for the other but if you have deionized water made from distilled waterthat has been sitting out exposed to air it becomes ordinary distilled water. Distilled water is your water cooling friend. Deionized water and distilled water are both in the running but you may not even know what they are. Distilled water has been boiled so that it evaporates and then re condensed leaving most impurities behind.
That s more than enough for your pump to move the liquid around and take heat from the blocks to. This leaves distilled water ionically hungry so it will actually strip electrons from the metals in a cooling system as it attempts to chemically re balance itself. Both of these types of water meet the qualifications of purified water and fall way below the 10 ppm limit. Deionized di water is water that has been treated to remove all ions typically that means all of the dissolved mineral salts.
