If you do not dilute dex cool with water, it may lead to overheating and potential damage to the engine, as concentrated coolant can have a higher boiling point and lower heat transfer efficiency. Additionally, undiluted coolant can be corrosive to engine components and may not provide adequate protection against freezing or rust. It is essential to follow manufacturer guidelines for proper dilution ratios to ensure optimal performance and longevity of the cooling system.
