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
container and in a location which is out
of reach of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethylene glycol. For this
reason, do not spill extended-duty anti-
freeze with corrosion inhibitor on hot
engine parts. It could ignite and cause
serious burns.

Checking coolant level

Correct 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, but no more than 0.8 in (2 cm)
above it – 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 – do
not overfill.

Comply with the applicable envi-
ronmental laws regulating the

disposal of extended-duty antifreeze
with corrosion inhibitor.
