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 factory specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store it in its original container
and in a location which is out of reach
of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethyleneÐglycol. For this
reason, do not spill antifreeze with
corrosion inhibitor on hot engine parts.
It could catch fire and cause burns.<
Checking coolant level and
adding coolantCorrect coolant level when the engine
is cold (approx. 687/206):
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 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).380de081
1. Start by turning the cap counter-
clockwise. Pause to allow any accu-
mulated pressure to escape, then
open
2. 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.<
