Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
To avoid the possibility of damage later
on, never use anything other than fac-
tory-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 them in their original container
and in a location that is inaccessible to
children. Extended-duty antifreeze with
corrosion inhibitor contains ethylene
glycol, a flammable substance. For this
reason, do not spill antifreeze with cor-
rosion inhibitor on hot engine parts. It
could ignite and cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<
Checking coolant levelCorrect coolant level when the engine
is cold (approx. 68 7 or 20 6):
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
end of the red float is aligned with the
upper edge of the filler opening (refer
to the arrow in the illustration), or max.
0.8 in (2 cm) higher, that is up to the
second mark on the float (see also the
schematic diagram next to the filler
opening).460de053
Add coolant Wait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be lo-
cated in the blue zone. If it is not, there
is a danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are
required.
Replace the coolant every four years.
