When to change antifreeze or how often to change antifreeze/when to change coolant

The automaker specifies how often coolant should be changed. Please check the owner’s manual or ask your dealer or garage.

How to check antifreeze?

Checking antifreeze is very easy.

There is no need to remove the cap on the radiator. Just check to see if the liquid reaches the “full” mark on the side of the reservoir. If it doesn’t, add a 50/50 mix of water and antifreeze. Some coolants are premixed, so read the instructions on the container to see if you need to add water or can use it as-is.

Only add water to the coolant system in an emergency. If this happens, you’ll have to do a complete flush and change the coolant if the water concentration is above 60% in the coolant after the top-up.

How to flush antifreeze/how to drain engine coolant, change coolant?

Every car model is different when it comes to changing antifreeze. It can be a little tricky to remove all the liquid. In some cases, several screws have to be removed to flush the system. Refilling the system can be even more difficult when there is air in the top parts of the engine. We therefore recommend that you have your dealer change the coolant.
