The

ís
mounted
in

The
fuel
pump
delivers
fuel
at

to
the
fuel
injection
system
.
A
pressure
regulator
maintains
system
pressure
.
The
quantity
of
fuel
sup-
plied
exceeds
demand,
so
excess
fuel
retums
to
the

via
a

GENERAL
This
section
covers
repair
and
troubleshooting
information
for
the
engine
cooling
system
.
For
heater
core
and
related
heating
and
air
conditioning
components,
see640
Heating
and
Air
Conditioning
.
Coolant
Pump
and
Thermostat
A
centrifuga¡-type
coolant
pump
is
mounted
to
the
front
of
the
engíne
.
The
belt-driven
pump
circulates
coolant
through
the
system
whenever
the
engíne
is
running
.
A
thermostat
con-
trols
the
flow
of
coolant
into
the
radiator
.
When
the
engíne
is
cold
the
thermostat
is
closed
so
coolant
bypasses
the
radiator,
recirculating
from
the
engíne
directly
back
to
the
pump
.
When
the
engíne
reaches
operating
tem-
perature,
the
thermostat
opens
and
coolant
circulates
through
the
whole
system
including
the
radiator
.
Radiator
and
Expansion
Tank
The
radiator
is
a
crossflow
design
.
A
translucent
expansion
tank
provides
for
coolant
expansion
at
higher
temperatures
and
easy
monitoringof
the
coolant
leve¡
.
On
4-cylinder
modeis,
the
radiator
expansion
tank
is
integral
with
the
radiator
.

NOTE-
The
traction
control
system
referred
to
as
AST
(all
sea-
son
traction)
may
also
be
referred
to
as
ASC
(Automat-
ic
Stability
Control)
and
ASC+T
(Automatic
Stability
Control+Traction)
.
The
AST
system
improves
traction
by
electronically
apply-
ing
the
rear
brakes
when
therear
drive
wheels
are
spinning
at
a
faster
rate
than
the
front
wheels
.
The
combined
ABS/AST
control
module,
operating
through
the
ABS
hydraulic
control
unit,
modulates
braking
force
at
therear
wheels
.
In
addition,
AST
uses
retarded
ignition
timing
and
an
auxil-iary
engine
throttle
plate
to
reduceengine
torque
and
maintain
vehicle
stability
.
The
auxiliary
throttle
plate
is
held
open
by
spring
pressure
.
The
AST
system
actívates
the
auxiliary
throttie
position
motor
(ADS)
to
cose
the
AST
throttle
as
needed
.
This
reduces
the
volume
of
engine
intake
air
.
Due
to
the
throttle
closing
very
rapidly
during
AST
operationthe
driver
cannot
increase
theengine
power
output
regardless
of
how
far
theaccelerator
pedal
is
pushed
to
the
floor
.
The
auxiliary
throttle
plate
is
placed
ahead
of
the
conven-
tional
throttle
plate
in
the
throttle
body
.
Traction
control
also
comes
into
operationduringdecelera-
tion
.
Decelerating
on
snowy
or
icy
road
surfaces
can
lead
to
rear
wheel
slip
.
If
a
rear
wheel
startsto
drag
or
lock
up
when
the
throttle
is
closed
rapidly
orduringdownshifting,the
AST
system
can
limit
the
problem
by
advancing
the
ignition
timing
.
A
switch
on
the
center
console
is
used
to
togglethe
AST
on
or
off
.
The
AST
system
is
designed
to
be
maintenance
free
.
There
are
no
adjustments
that
can
be
made
.
Repair
and
trouble-
shooting
of
the
AST
system
requires
special
test
equipment
andknowledgeand
should
be
performed
only
by
an
autho-
rized
BMW
dealer
.
