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.<
