Changing the coolant
The coolant, consisting of a mixture of water and radiator antifreeze, plays a crucial role in vehicles as it protects the engine and cooling system from both frost and overheating and keeps it at the optimal operating temperature. But that is not all. It also protects the cooling system from corrosion, deposits and foaming. Without the right radiator antifreeze, the service life and performance of the engine are seriously jeopardized.
Why are regular coolant changes so important?
Over time, the additives contained in the radiator antifreeze lose some of their effectiveness, the engine system becomes more susceptible to corrosion and is not sufficiently protected against heat or frost. In order to protect, maintain and clean the cooling system over the long term, it is necessary to change the coolant regularly and clean the system accordingly. Otherwise, this can have serious consequences:
- Cooling system failure
- Risk of engine overheating or even engine damage
- Frost and resulting severe damage to the cooling system
- Corrosion and leaks in the cooling system
- Overpressure and resulting damage to the system
Defective water pump, blocked thermostat and clogged heat exchanger due to unremoved deposits
How often should I change the coolant?
Generally, the coolant change is part of your service plan and depends on the vehicle and the radiator antifreeze used. Depending on the product used, regular replacement is required every three to four years. You can find out when it is time to do this again in your vehicle's service booklet.

The coolant change should always be carried out by a professional. Some coolant changes require special equipment and knowledge. Not using a professional runs the risk of the system not being cleaned properly and the cooling system not being able to work properly as a result. We’d be glad to advise you in your LIQUI MOLY Service Garage.

The right radiator antifreeze for the coolant change
Modern radiator antifreezes are service products specially developed for certain cooling systems. Using inferior or even incorrect coolants can have serious consequences:
- Risk of engine overheating
- Frost and corrosion in the cooling system
- Loss of warranty
- Leaks and damage in the cooling system due to material incompatibility
- Reduced service intervals
Which radiator antifreeze is the right one for my vehicle?
It’s all about the specification: The most important factor when selecting radiator antifreeze is the manufacturer’s specifications. Only this specification guarantees the optimum function of the coolant. This is particularly important when topping up the radiator antifreeze!
We offer you a wide range of products, not only in types of engine oil, but also in types of radiator antifreeze. As always, the highest quality is paramount.
