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 coolantReplace the coolant every three years.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
