Volkswagen Coolant

Your Volkswagen engine relies on coolant to run properly, keeping it cool in warmer months and preventing it from freezing up in colder months. There are a couple of evolutions of the coolant VW use meaning there is no one-for-all solution. At Links Automotive, our team of Volkswagen experts are always on hand to assist you with advice on coolant and replacement when needed. 

This blog uncovers the importance of coolant in your Volkswagen. It offers  tips on identifying the right coolant and the dangers of not using the correct coolant and what can happen if you neglect service intervals in your Volkswagen.

Read on to deep dive into our Volkswagen coolant guide!

The Role of Coolant In Your Volkswagen

Coolant is used in your Volkswagen’s cooling system to regulate engine temperature. Circulating through your engine, coolant is a liquid that aids in absorbing heat from the engine and transfers it  away and through the radiator. Your radiator helps lower the temperature of the coolant as it is pumped around the engine again as the cycle repeats.

Coolant is made up of a mixture of water and antifreeze. Antifreeze is a set of concentrated chemical additives which lower the freezing point and raise the boiling point of normal water, offering protection against corrosion on the engines cooling system.

Why Use Coolant In Your Engine?

The core functions of coolant in your Volkswagen are:

• Thermal Regulation –  Volkswagen engines generate heat while running at thousands of revolutions per minute (rpm). Coolant helps dissipate this heat, preventing the engine from overheating, especially in warmer climates where outside temperatures can soar above 40°C.
• Freeze Prevention –  In chilly winter conditions, Volkswagens are exposed to freezing temperatures, risking the internal liquids turning into ice without the help of coolant. This is crucial because Volkswagens are engineered to operate in temperatures as low as -40°C.
• Corrosion Resistance –  The coolant contains special additives that reduce the likelihood of rust and corrosion on the internal components of a Volkswagen engine, enhancing its durability over time.
• Protection Against Erosion –  Coolant plays a key role in preventing the erosion of engine parts during electrolysis, a chemical process that occurs when electricity passes through a liquid.
• Extended Lifespan of Components –  Quality coolant not only protects metal engine parts but also extends the life of rubber and plastic hoses, contributing to the overall longevity of a Volkswagen engine.
• Lubrication –  The efficient movement of fluid is crucial for the proper functioning of the water pump in Volkswagens. High-pressure, fast-flowing coolant ensures that the fluid moves freely, allowing the water pump to seal and operate effectively.

Your Volkswagen was carefully engineered to use a specific type and amount of liquid coolant. If the wrong coolant is used the engine could suffer from long-lasting damage. This is also a risk when coolant is not replaced when the manufacturer recommends it, for example during a service.

Which Coolant Should You Use In Your Volkswagen?

The type of coolant that should be used in your Volkswagen ultimately depends on your model, model year and engine. To ensure optimum engine efficiency, function and corrosion prevention, the correct coolant must be used. 

To find the correct coolant type for your Volkswagen, consult your owner’s manual. This is usually the best place to find how much coolant your engine needs too. If you are unable to source this information, call or visit Links Automotive, we are your local Volkswagen specialists who can help. 

How Coolant Is Affected by Weather Conditions and Driving Habits

In more extreme climates, your Volkswagen cooling system needs to work harder. Coolant is used to maintain the most efficient engine temperature and if outside temperatures increase, the system needs to work extra hard.

Hotter weather results in higher coolant temperatures and increased chances of overheating and component faults. Lower-speed driving also makes it more likely that your engine will overheat, because of reduced airflow. 

It is essential to use the correct coolant type and also maintain the right amount of coolant circulating through your engine, ensuring it is also replaced according to manufacturer guidelines. At Links Automotive, our specialist technicians are Volkswagen experts. They offer guidance on the correct replacement intervals and the appropriate coolant type for your specific Volkswagen.

Choosing Coolant In Your High Mileage Volkswagen

If your Volkswagen has high mileage, your cooling system should be checked more regularly. Only a specialist garage will have the experience, knowledge and tools to perform inspection and replacement of coolant. This is where our team of experienced technicians come in. At Links Automotive, we have been performing regular maintenance on Volkswagen cooling systems for a long time, being the reliable source for Volkswagen owners in the Macclesfield area.

It’s recommended to change the coolant based on Volkswagen’s suggested intervals. Additionally, it’s important to properly flush the system, inspect for leaks, fill it up and bleed it to make sure your Volkswagen stays cool while running the engine normally.

What If You Use The Wrong Coolant In Your Volkswagen?

Your Volkswagen engine will not like it when you use the wrong coolant, as it can lead to all kinds of issues. Corrosion is the main problem, which affects the water pump and seals, resulting in leaks and damage to these important components. The radiator, which is responsible for taking the heat out of the coolant, along with the surrounding hoses, could become damaged too.

The hoses are essential as they keep the coolant circulating in the engine bay. If the hoses fail, then they will cause leaks and overheating. This leads to the worst engine failure you can have – a blown head gasket. It is also one of the most expensive repairs. The reason why your head gasket blows is down to an overheating engine, as heat causes metal parts to expand and is a result of not properly looking after your coolant or cooling system.

How To Make Sure You Use The Correct Coolant In Your Volkswagen

At Links Automotive, we know all Volkswagen vehicles. With our team of experts on hand to test and replace coolant and cooling system parts, your Volkswagen is in good hands. Whilst you may be able to perform some maintenance yourself by consulting your user manual, our specialist technicians will use advanced tools, save you time and properly bleed and test the cooling system after renewal.

Do This To Maximise The Performance And Life of Your Volkswagen Engine

Coolant is vital in the performance and longevity of your Volkswagen. If you check your cooling system regularly and replace it according to manufacturer recommendations, then you will go a long way in securing a long-term future for your vehicle.
