Did you know …? Glysantin® - why approval matters
At the start of the year many cars are due for their next inspection. Typical maintenance jobs in the workshop include checking, topping up and changing the fluids used in the vehicle, such as engine oil, brake fluid and coolant. The importance of the coolant is often underestimated, and this can have serious consequences. “If a product not approved by the vehicle manufacturer is used when the coolant is replaced, there is a risk of damage to the engine,” warns Dr. Harald Dietl, Manager in Technical Marketing Automotive and Refinery Chemicals at BASF.
“A coolant like Glysantin® is just as much a high-tech product as, for example, a synthetic engine oil and must therefore fit the type of vehicle exactly. Unfortunately, every year more damage is still caused to engines by the wrong coolant than by the wrong oil, explains Dietl. Only a coolant approved by the manufacturer can effectively protect the engine not only against freezing in winter and overheating in summer, but also against corrosion all year round. Each manufacturer sets different requirements for its coolants, depending on the particular metals and plastics used in the engine and cooling system. That is why BASF also offers the right type of Glysantin® for every vehicle.
On no account should different coolants be mixed together, stresses Dietl. Such mixing can cause the metal components in the cooling system – radiator, water pump, crankcase and cylinder head – to corrode. The corrosion particles thus created then block up the fine coolant ducts and reduce the cooling performance. Even in the winter an engine can overheat quickly as a result.
And there is another risk in using a non-approved coolant or a mixture of different coolants: plastic components, hoses and seals can become damaged. Over time the seals become porous and the hoses are attacked so badly that they finally burst. The cylinder head gasket can also be damaged, which means that oil can leak into the cooling water; the result is an expensive and avoidable repair in the workshop.
Automobile manufacturers have very stringent quality requirements for coolants. Before a coolant is approved it has to pass an average of 30 different tests. These include, for example, corrosion tests, compatibility tests with original components, tests on the engine test bench and fleet tests. Only when the coolant has successfully undergone all the tests does it receive approval from the vehicle manufacturer. In all these areas, the best performance is always achieved by Glysantin® from BASF. “By contrast, low-cost antifreeze products and universal coolants, which are unfortunately appearing more and more on the market, have not been through any of these tests, nor do they have any manufacturer’s approval,” stresses Dietl.
The premium engine coolant in the white bottle with the unmistakable red logo has the most official approvals from European car manufacturers. Whether from Audi, BMW, Daimler, Porsche, Opel, Skoda, Seat, Peugeot, Citroen or VW, the majority of new cars sold in Europe are filled in the factory and delivered with the dependable protection from Ludwigshafen.
