Engine Coolant Flush
An engine coolant flush done at regular intervals can extend the life of your car. Engine coolant, also known as antifreeze, stops the water in your engine's cooling system from freezing. It also does a number of other important jobs, so it is 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 use. There's a concentrated form and a form that is ready mixed with water.
The ready-mixed form is commonly referred to as engine coolant. Use it for top-ups and replacements. The concentrated form needs to be diluted with water, usually around 50% antifreeze and 50% water. Check the instructions for the right ratio to use.
Many cars made after 1998 require antifreeze that uses silicate-free, organic acid (OAT) technology. Older cars usually require a more traditional type of antifreeze. OAT antifreeze is not recommended.
