All engines, including those in an Audi or Volkswagen, operate at high temperatures. Even just a few minutes of running your car causes the temperature to rise to 220 degrees. As a result, all vehicles, including Audi and Volkswagen, have a cooling system. The cooling system pumps fluid, coolant through the engine, where it gets hot and moves to the radiator to cool. Therefore, if you have a coolant leak in your vehicle, you must address it quickly.

Why is Coolant Important?

Coolant is a critical part of the operation of your car. You must have the right amount of fluid; otherwise, you are at risk for engine damage. If your coolant to water ratio is out of balance, you could have negative performance and fuel economy. Therefore, you should check your coolant level regularly. If you find that you have to add coolant on a consistent basis, you may have a coolant leak.

How Do I Find a Coolant Leak?

Finding a coolant leak is probably easier than you realize. You may be able to see fluid leaking from the hood of your car. You may see bubbles in the reservoir or where the hose connects. It would be best if you were careful when checking the fluid because the engine must be cooled completely. If not, you could burn yourself with the steam that escapes. You do not want to open the radiator cap if the engine is hot. You may also find that your engine is overheating, and the temperature gauge on your dashboard may be in the red area. There could also be steam coming from your hood. Your car may stall, or the low coolant light may come on.

What To Do When You Have a Coolant Leak

You have to first determine the size of the leak in order to repair it. If there is a cracked hose, you must replace the hose to stop the leak. These components wear out over time, making it essential to replace the hoses, reservoir tank, and radiator cap. The hose clamps can become loose over time, requiring you to check them to ensure they are tight. When they become loose, this could be the cause of a coolant leak. Your coolant leak may be caused by a blown head gasket which is a severe condition. The long term goal should be to replace the head gasket. However, you may be able to use sealant for breaks or cracks that are not serious. You can use sealant for holes that you might find in the radiator.
