Common Volkswagen Scirocco Radiator Problems and Ways to Solve Them
If there's one part that your Volkswagen Scirocco can't do without, it is the radiator. As a component of the cooling system, this part absorbs the heat from the passing coolant, therefore preventing overheating and other problems. Check out the list below for some of the things that you need to watch out for when it comes to your vehicle's radiator:
Sometimes, due to age and road debris, the radiator of your Volkswagen Scirocco may get damaged and start to leak. Once this happens, coolant level will become low, which will eventually lead to overheating and other issues. As a solution to this problem, you should replace the radiator immediately. However, if you are looking for a temporary solution, then you can try using a cold weld epoxy, a commercial radiator leak sealant, or ground pepper. In case you want to use ground pepper, just pour 1-2 teaspoons into the radiator because pepper instantly swells and blocks leaks once it comes into contact with water.
Another problem that you will encounter with your Volkswagen Scirocco radiator is rust. Usually, because of contaminants and the varying temperatures in the engine block, the radiator becomes rusty, therefore resulting to overheating, damage of cooling system components, and poor cooling performance. To remove the rust, you need to clean your immediately. Fortunately, you don't have to visit a service center to get this job done. You only need to purchase a cooling system flush or cleaner and antifreeze that suits your vehicle from an auto parts store.
Overheating, leaks, and water pump damage-if you are experiencing these problems, then you'd better pop the hood and make sure that the radiator is not clogged. Usually, because of radiator fluid that has not been changed for a long time, sediments form, therefore blocking the fins and hoses of your vehicle's radiator. If this is the case, you need to flush the radiator at once. Fortunately, this can be done in a few hours, and you don't need special tools to do it. Just make sure that aside from the commercially-bought radiator flush, you will also flush the system with water until all sediments are removed.
