Coolant Flush

Why You Shouldn’t Fill Your Radiator Only with Water

Water alone can cool your engine, so why do you need coolant at all? Typically, radiators are filled with a 50/50 mixture of coolant and water. Coolant - also known as antifreeze - is specially formulated to cool and protect your engine more than water alone ever could. Coolant is added for the following reasons:

  1. To keep the water in your radiator and engine from freezing in cold temperatures.
  2. To prevent the water from overheating no matter what the exterior temperature.
  3. To help lubricate the components in the cooling system.
  4. To prevent the water from rusting and corroding the system’s internal parts.
