Here you can find anything you need to know about GLYSANTIN®
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.
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.
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.
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.
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.
Generally, we do not recommend this. The composition of different products vary widely, and mixing them can lead to severe compatibility problems.
GLYSANTIN® Ready Mix products are already diluted with water at a ratio of 50:50. They are ready for use and do not have to be diluted any further.
As this is the same product, one being a concentrate and the other already being diluted with water (e.g. GLYSANTIN® G48® Concentrate and GLYSANTIN® G48® Ready Mix), these can be mixed.
Drain the coolant completely and flush the system thoroughly with water (we recommend a 15% GLYSANTIN® mixture) and then fill with the correct GLYSANTIN® in the appropriate concentration.
Mixing different engine coolants or using the wrong coolant can impair the performance of the special additive packages; this can result in increased corrosion to the radiator. The protective layers in the cooling system gradually become thinner and more porous and the engine coolant needs to be changed at more frequent intervals. Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket. This can lead to damage to the engine in the worst case.
In the cooling system, pH buffers and additives are gradually degraded and become less effective with time. We therefore recommend a complete change of coolant every three to four years. It is also strongly recommended to clean the cooling system and completely renew the coolant whenever the cooling system is repaired. This prevents rust, contamination and suspended particles remaining in the system leading to scale, corrosion and other damage.
GLYSANTIN® products are not backwards compatible. Please use the product specified in the orientation lists. This is because the technologies used are not compatible. One exception are cars manufactured by Volvo. Volvo Cars tested and confirmed the compatibility of GLYSANTIN® G64® with older engine generations.
Officially approved engine coolants can be changed during the warranty period without affecting the engine manufacturer’s warranty. However, filling the cooling system with coolant, cooling fluids or antifreeze that have not been approved during the warranty period can render the manufacturer’s warranty invalid.

No! Due to the continuous changes in engine technology, it is absolutely necessary to adapt the coolant technology as well. The individual coolant technologies cannot be mixed and are not compatible with each other and should be used according to the respective engine or coolant technology.
Vehicle manufacturers do not “recommend” any particular engine coolants, but they do grant official approvals. New vehicles are filled with approved engine coolants when they leave the factory and these can be replaced during the warranty period without affecting the manufacturer’s warranty. On average, engine coolants have to undergo thirty different tests before they are approved by the engine manufacturers. These consist of different corrosion and compatibility tests with the original components of the cooling system, but also engine and vehicle tests. Engine manufacturers do not give official approval to coolants until they have passed all the tests. The process takes three to five years and is very expensive. If any changes are made to the coolant formula, the entire approval process has to be repeated. GLYSANTIN® has the most approvals from leading vehicle manufacturers.
On average, about 150 litres of coolant are pumped around the cooling system of a car engine each minute. This is even more in commercial vehicles. In doing so, the mixture of water and coolant comes into contact with numerous different materials. Unless the correct engine coolant is selected, the high temperatures and high pressure differences in the system create ideal conditions for corrosion and cavitation. Without any protection, the cooling water can etch deep holes into the metal and damage the cylinder head, cylinder liners and water pump. This can lead to failure of the cooling system and even damage the engine beyond repair. For this reason, vehicle manufacturers have very specific demands on the performance of engine coolants, depending on which materials they come into contact with. GLYSANTIN® has been working in close cooperation with all leading automobile manufacturers for many decades and has developed a suitable product for every engine.
The color of the coolant is defined in the specification from the vehicle manufacturers and is also a small but important part of the official approval from the vehicle manufacturers. Important note: It is not possible to identify the engine coolant by the color alone. The color of the engine coolant does not identify the chemical and technical properties.
In their sealed original packaging, GLYSANTIN® products have a shelf life of at least three years from the date of manufacture. Its service life after it has been diluted with water depends on the vehicle manufacturer’s specifications. We generally recommend changing coolants every 3-4 years.
GLYSANTIN® contains ethylene glycol (ethanediol), which is harmful if swallowed, and should be prevented by the use of a bitter compound. Nevertheless, if you do swallow GLYSANTIN®, you should seek medical attention immediately and show the doctor the packaging or label. Avoid contact with skin and eyes. GLYSANTIN® must be kept out of the reach of children and pets. You will also find an emergency telephone number on the GLYSANTIN® packaging you can call for further qualified assistance.
This date specifies the month that the GLYSANTIN® was filled into the container.
Yes, GLYSANTIN® products can be used for other applications, i.e. heavy duty like stationary engines, trains, offroad vehicles and marine as well as wind power applications. Please find more information about GLYSANTIN® in other applications as well as the approval list by clicking in the link below.
For all motorcycles (except BMW), we recommend the product GLYSANTIN® G30®. For BMW motorcycles, GLYSANTIN® G48® is officially approved.
No. GLYSANTIN® is based on monoethylene glycol and not on propylene glycol.
In the document “GLYSANTIN® Graphs” you can find a set of data that have been compiled under normal pressure in the temperature range from -40°C to +100°C in different concentrations. This means data like i.e. density, viscosity, specific heat capacity, heat conductivity, vapor pressure, boiling point and freezing point.
