Coolant

Do not add coolant to the cooling

system when the engine is hot. If

you do, escaping coolant can cause

scalds.

To avoid the possibility of damage later

on, never use anything other than

factory-approved, nitrite and amino-

free extended-duty antifreeze with

corrosion inhibitor. Your BMW center is

familiar with the official specifications.

Antifreeze and anticorrosion agents are

hazardous to health. You should always

store it in its original container and in a

location which is out of reach of chil-

dren. Extended-duty antifreeze with

corrosion inhibitor contains ethylene

glycol, a flammable substance. For this

reason, do not spill long-life antifreeze

with corrosion inhibitor on hot engine

parts. It could catch fire and cause

serious burns.<

Checking the coolant level and

adding coolant

Check the coolant level when the

engine is cold (approx. 68 7 or

+20 6). The coolant gauge needle in

the instrument cluster must be located

in the blue field; otherwise you could be

scalded when adding more fluid.

1 Open the cap for the expansion tank

by turning it slightly counterclockwise

to allow accumulated pressure to

escape. Then open.

2 The coolant level is correct whenever

the upper end of the red float rod is

aligned with the upper edge of the

filler neck (refer to the arrow in the

illustration and the schematic

diagram next to the filler neck as

well).

3 If necessary, add coolant. If the

coolant is low, slowly add coolant

until the correct level is reached – do

not overfill.

The coolant is a mixture of water and

extended-duty antifreeze with corrosion

inhibitor. Always maintain the pres-

cribed all-season 50:50 mixture ratio for

year-round protection against internal

corrosion. No other additives are

required.

Change the coolant

Replace the coolant every three years.

Comply with the applicable envi-

ronmental laws regulating the

disposal of extended-duty antifreeze

with corrosion inhibitor.<
