Volkswagen Scirocco Radiator

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:

Radiator leaks

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.

Radiator rust

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.

Clogged radiator

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.

  • Best Practices to Make Your Volkswagen Scirocco Radiator Last

    The radiator of your Volkswagen Scirocco is a very important component of the cooling system. Without it, your vehicle will overheat, and gas mileage will be greatly reduced. For these reasons, keeping this part in tip-top shape is something that you should do routinely. Follow some of the tips listed below to make your radiator last for a long time.

    Use the right radiator fluid when filling your radiator.

    Nowadays, car parts manufacturers produce different kinds of radiator fluids for different vehicles. However, not all of them are made equal, so their performances can't be guaranteed. For this reason, make sure that you will use the right kind of fluid for your radiator. For optimum performance, you should try using a glycol-based antifreeze.

    Check your radiator for leaks and other signs of damage routinely.

    Although your Volkswagen Scirocco's radiator is built to last for a long time, its components will still fail due to various factors. And so, to avoid unexpected performance problems, make sure that you will inspect the radiator and its components for leaks and other signs of damage. In case there are holes, then you'd better get a replacement radiator immediately. But, if you don't want to spend a lot of money, then you can try doing some temporary repairs.

    Flush your vehicle's radiator periodically.

    Over time, the radiator of your engine will become filled with sludge and other contaminants that come from the engine. Once this happens, your Volkswagen Scirocco may overheat because heat will no longer be transferred efficiently. To prevent this, make sure that you will flush your radiator periodically. This can be done at home, and you only need a radiator flush solution that can be purchased from an auto parts store. However, make sure that you will top up the radiator with coolant and distilled water afterwards.

    Avoid overdosing your Volkswagen Scirocco radiator with antifreeze.

    The saying "the more the merrier" is something that you should not follow all the time especially in terms of radiator maintenance. For instance, if you think that filling this part with 100 percent antifreeze is correct, then you'd better stop believing this at once. To make your radiator last for a long time, you need to fill it with equal amounts of water and antifreeze. But, if the weather is too cold, then you can increase the amount of antifreeze to 69 percent.
