Can the Ratio of Antifreeze to Water in an Engine Affect Its Cooling Ability?

Antifreeze and Water

When refilling antifreeze in a vehicle, logical reasoning suggests using more concentrated antifreeze would produce better results. Unfortunately, straight antifreeze can be detrimental to an engine. Antifreeze must be mixed with an appropriate ratio of water to ensure it does not boil or freeze. If too much antifreeze is left concentrated, the solution will boil prematurely. Similarly, too much water in the mixture will lead to premature freezing. Both of these states can severely damage a vehicle, and auto technicians must ensure all antifreeze-to-water ratios are mixed in accordance with the vehicle and manufacturer specifications.
