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
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor. Your BMW center is
familiar with the official specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their original
containers and in a location inacces-
sible to children. Extended-duty anti-
freeze with corrosion inhibitor contains
ethylene glycol, a flammable
substance. For this reason, do not spill
extended-duty antifreeze with corrosion
inhibitor on hot engine parts. It could
catch fire and cause burns.<
Check the coolant level and
add coolant
Check the coolant level when the
engine is cold (approx. 68 7 or
+20 6).
1. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape. Then open
2. 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 in (2 cm)
above it Ð that is, up to the second
mark on the float (refer also to the
schematic diagram next to the filler
neck)
3. If necessary, add coolant. If the
coolant is low, slowly add
coolant until the correct level is
reached Ñ do not overfill.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
