What Should I Do If My Car Has a Coolant Leak?

Your vehicle’s engine has many components, and each plays an important role in its performance. A coolant leak may sound minor, but it can have lasting impacts on your engine – and potentially require costly repairs! Read on to learn more.

What Is Car Engine Coolant?

Coolant, also known as antifreeze, protects your engine from overheating. It also provides much-needed lubrication to prevent damage to the water pump, head gasket, cylinder and more. The engine coolant circulates through the engine to maintain a consistent operating temperature, so it’s important that fluids stay at the right levels.

How Does It Work?

To function as it should, coolant must move continuously. A water pump keeps it flowing and absorbing the engine’s heat along the way. It moves through hoses to the radiator, where it cools down, and then back into the engine. If the grille does not allow for sufficient airflow to cool the liquid, a fan behind the radiator pulls air through it.

How Often Should You Change Your Engine Coolant?

Here at Low Country Volkswagen, our certified technicians recommend changing your engine’s coolant every 30,000 miles or about every two years. Because coolant change intervals vary from vehicle to vehicle, it is best to consult your owner’s manual.

How To Know When Your Engine Coolant Needs To Be Changed

Here are some signs that it’s time to change your engine coolant:

• You see white smoke is coming from the tailpipe (could hint at an internal leak)
• You smell a sweet, burnt odor
• Your temperature gauge rises above normal levels or the warning light is illuminated
• You see coolant on the ground under your vehicle
• You hear a grinding noise coming from under the hood
• You see steam coming from the engine
