Changing coolants

Tips for the correct coolant

1. Glysantin® is not just an antifreeze: it protects the cooling system all year round.
2. If the vehicle is six years old or older, you need to change the coolant every three to four years
3. The coolant should always be changed completely after repairs have been done and the cooling system should be flushed out and cleaned.
4. Never use coolants alone in their concentrated form. You must always dilute coolants such as Glysantin®.
5. Use clean water.
6. Always take care to ensure that coolants are diluted in the correct proportions.
7. Never mix different types of coolant.
8. Always follow the instructions of the motor manufacturer.

Changing coolants - How to get the best results

The coolants used in passenger vehicles need to be changed every three to four years, depending on the type of product. This is important, because the additives contained in the coolant gradually break down. Glysantin® still prevents the cooling water from freezing, but it can no longer be fully ensured that the customized additives will still be able to protect the cooling system from corrosion.
It is important to completely drain all of the old cooling water. The best results are obtained if the cooling system is flushed with water before the new coolant is poured in. Please note that cooling water may not be discharged into the drains. It is important to ensure that the coolant is approved by the manufacturer of the vehicle.

How should coolants be diluted?

Glysantin® always needs to be diluted. Best with demineralized or distilled water. Also tap water is can mostly be used if it is not harder than 3.5 mmol/l. If your water quality is unclear or your tap water very hard we recommend to always use demineralized or distilled water.
We would always recommend diluting Glysantin® 50:50 with water when you change the coolant and we would recommend using standard Glysantin® products to ensure optimum protection from corrosion, overheating and frost. Make sure that you dilute the coolant correctly: the concentration of Glysantin® should not be less than 33 % and not more than 60 %.

Is it possible to mix different types of coolant?

It is important to make a distinction between coolants that contain silicates and those that are free of silicates. Different types of products should never be mixed with each other, because this impairs the effectiveness of the additive packages. In the worst case, lasting damage can be done to the engine.
