Coolant
Do not add coolant to the cooling
system when the engine is hot.
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
protectant. Your authorized BMW cen-
ter is familiar with the official specifica-
tions.
Antifreeze and anti-corrosion agents
are hazardous to health. Store anti-
freeze and anti-corrosion agents in their
original containers where they are inac-
cessible to children.
Extended-duty antifreeze with corrosion
inhibitor contains ethylene glycol - a
flammable substance. For this reason,
do not spill antifreeze with corrosion in-
hibitor on hot engine components. It
could catch fire and cause serious
burns.<
Correct coolant level when the engine
is cold (approx. 687/206):
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 the sche-
matic diagram next to the cap).
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 re-
quired.
Replace the coolant every four years.380de081
To add coolantWait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant temper-
ature gauge in the instrument cluster
must be located in the blue zone; other-
wise, there is a danger of scalding.
1 Start by turning the cap counter-
clockwise. Pause to allow any accu-
mulated pressure to escape, then re-
move the cap
2 If the coolant is low, slowly add cool-
ant until the correct level is reached –
do not overfill.
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<
