Coolant

Fill the cooling system only when the engine has cooled down, otherwise you risk scalding.◄

Coolant consists of water and antifreeze. Not all antifreezes available on the market are suitable for your BMW.

To find out which antifreeze products are suitable, contact a BMW service center.

To avoid engine damage, use only the recommended antifreeze. Antifreeze is hazardous to health, so observe the instructions printed on its packaging.◄

When disposing of antifreeze, observe environmental protection laws.◄

Checking the Coolant Level

1. The engine must be at room temperature.

2. First release the excess pressure in the reservoir by turning the cap slightly counterclockwise, then open the reservoir.

3. Under normal conditions, the coolant level should be between the "Min" and "Max" marks, see illustration next to the filler neck.

4. If necessary, slowly top up the fluid, without overfilling.
5. Tighten the cap until it clicks audibly.
6. Eliminate the cause of the coolant leak as soon as possible.
