Is antifreeze corrosive
WebLet’s talk about the most common additives found in modern coolants, and how each one can damage your engine: 1. Borate. Borate is a pH buffer that: Lowers the freezing point of the coolant. Increases the boiling point of the coolant. Reduces friction and sludge. Prevents corrosion at high temperatures. WebThe Need for “Antifreeze” • Water is almost a perfect fluid… – Excellent heat transfer – Excellent health & safety – Low cost • BUT. water freezes at 0. o. C / 32. o. F • Antifreeze protects system piping and components from damage caused by freezing – Volume expansion due to ice crystals generates pressure
