Frequently Asked Questions
Why does coolant have to be changed?
Coolant has to be changed every three to four years depending on the product and the recommendation of the vehicle manufacturer. This is important, as the additives contained in coolants gradually degrade. Coolants retain their antifreeze function for a long time, but the corrosion inhibitors degrade over time and no longer protect the cooling system from damage.
Can coolants be poured down the drain?
No! GLYSANTIN® concentrated coolants always have to be diluted. Undiluted products do not have sufficient capacity to absorb the heat from the engine, which leads to overheating. Undiluted coolants can also become solid in winter. If you would like a product to use directly, then please use the pre-diluted GLYSANTIN® Ready Mix products.
In which ratio should GLYSANTIN® concentrate products be diluted with water?
When changing the coolant, we would always recommend that you dilute GLYSANTIN® concentrate products with water at a ratio of 50 : 50 in order to obtain the best possible protection against corrosion, overheating and frost. The concentration of GLYSANTIN® should be no less than 33% and no more than 60%. If you are looking for a product to use directly, please use the pre-diluted GLYSANTIN® Ready Mix products. As they are already pre-diluted at a ratio of 50 : 50, they can be used immediately.
Can normal tap water be used to dilute GLYSANTIN® concentrate products?
Normal tap water can usually be used to dilute coolant concentrates if it does not exceed 3.5 mmol/l (20 degrees German water hardness) or does not contain more than 100 ppm chlorine or sulfate. We recommend using demineralized or distilled water. If you would like to use the product directly without dilution, please use GLYSANTIN® Ready Mix products as they are already diluted with water and ready for use.
Can different GLYSANTIN® products be mixed with each other?
Chemically, but we do not recommend this. Each product contains a different combination of additives that are compatible with the different materials in the cooling system. Mixing different additives can impair their overall performance and reduce the level of corrosion protection.
