An engine coolant flush can extend the life of your car. We know how to do engine coolant flushes properly and pick the right antifreeze for your car.

An engine coolant flush done at regular intervals can extend the life of your car. Engine coolant, also knows as antifreeze, stops the water in your engine's cooling system from freezing. It also does a number of other important jobs, making it a vital car fluid to keep your engine running smoothly.

Check your owner's manual for the recommended interval for engine coolant flush on your vehicle. Use a trusted auto mechanic like Dulles South Chantilly Automotive to make sure this important maintenance is done right. 

The Importance of Antifreeze

Antifreeze is added to the water in an engine's cooling system in order to lower the freezing point. This means that the water will not freeze under normal cold weather conditions.

Antifreeze also raises the boiling point of engine coolant to prevent overheating. It protects your engine from corrosion, aids heat transfer, and prevents scale from building up internally.

Choose the Right Antifreeze

When you have an engine coolant flush, you have a choice of which antifreeze to go for. There's a concentrated form and a form that is ready mixed with water. The latter version is commonly referred to as engine coolant and can normally be used straightaway for top-ups and replacements. The concentrated form needs to be diluted with water, usually at a level of around 50% antifreeze and 50% water. Always check the instructions for the right ratio to use.

Many modern cars manufactured after 1998 require antifreeze that uses silicate-free, organic acid (OAT) technology. Older cars usually require a more traditional type of antifreeze that is not OAT based and does contain silicate.
