2000 BMW 323i Coolant antifreeze

Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather.
Adaptations in driving style should be
accompanied by preparations on the
vehicle itself to ensure that your
progress through the winter remains
safe and trouble-free.CoolantBe sure that the coolant mixture con-
tains the year-round ratio of 50:50
water and extended-duty antifreeze/
corrosion protection. This mixture pro-
vides protection against freezing down
to approx. Ð 34 7 (Ð 37 6). Replace
the coolant every four years.LocksBMW door lock deicer can be used to
free them if frozen. This deicer also
contains lubricant.
After its use, treatment with BMW lock
barrel grease is recommended.Rubber seals and components To prevent the weather-stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.

available from your BMW center.<
Snow chains BMW snow chains
* can be mounted on
both summer and winter tires. Mount
them in pairs on the rear wheels only
and comply with the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
For best performance, deactivate the
DSC when snow chains are mounted.
Refer to page 79.
Starting offWhen starting from a full stop in deep
snow or for "rocking" the vehicle to free
it, we recommend that you deactivate
the DSC system. Refer to page 79.Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. On down-
grades or slopes, shift down to the next
lower gear at an early point. Maintain an
adequate distance between yourself
and the car ahead.
BrakesWinter road conditions substantially re-
duce the traction available between the
tires and the road surface. Remember
that braking distances will be signifi-
cantly longer as a result.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.
If the ABS does not respond in a critical
braking situation and the wheels lock:
Reduce the pressure on the brake pedal
until the wheels just start to roll again
while still maintaining enough force to
continue braking.
Following that, increase pedal pressure
again. Reduce the pressure as the
wheels lock, then reapply pressure.
Repeat this procedure. This type of
staggered braking will reduce the brak-
ing distance, and the vehicle still re-
mains responsive to steering. It allows
you to steer around hazards once you
have reduced the pressure on the brake
pedal.

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 fac-
tory-approved, nitrite and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your BMW center is familiar
with the official specifications.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in their original container
and in a location that is inaccessible to
children. Extended-duty antifreeze with
corrosion inhibitor contains ethylene
glycol, a flammable substance. For this
reason, do not spill antifreeze with cor-
rosion inhibitor on hot engine parts. It
could ignite and cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<
Checking coolant levelCorrect coolant level when the engine
is cold (approx. 68 7 or 20 6):
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
end of the red float is aligned with the
upper edge of the filler opening (refer
to the arrow in the illustration), or max.
0.8 in (2 cm) higher, that is up to the
second mark on the float (see also the
schematic diagram next to the filler
opening).460de053
Add coolant Wait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be lo-
cated in the blue zone. If it is not, there
is a danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are
required.
Replace the coolant every four years.
