Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you do, escaping coolant can cause
burns.
To avoid the possibility of damage later
on, do not use anything other than fac-
tory-approved, nitrite and amino-free
extended-duty antifreeze with corrosion
inhibitor which can be used with alumi-
num radiator cores. Your BMW center
is familiar with the approved specifica-
tions.
Antifreeze and anti-corrosion agents
are hazardous to health. Store them in
their original containers. Keep the con-
tainers tightly closed and out of reach
of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethylene glycol. For this rea-
son, do not spill extended-duty anti-
freeze with corrosion inhibitor on hot
engine components. If you do, it could
be ignited and cause serious burns.
<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.

):
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck (refer to the arrow in the illustra-
tion), but no more than 0.8 inches
(2 cm) above it – that is, up to the sec-
ond mark on the float (refer also the
schematic diagram next to the filler
neck).
