WARNING
-
At
normal
operating
temperature
-
the
cooling
sys-
tem
is
pressurized
.
Allow
the
system
to
cool
before
opening
.
Release
the

slowly
to
allow
sale

.
With
the

cold,instan
a

Pressurize
thesystem
to
the
specification
listed

.
Pressure
should
not
drop
more
than

.
If
the
pressure
drops
rapidly
and
there
is
no
sign
of
an
externa¡
leak,
the
cylinder

gasket
may
be
faulty
.
Considera

as
described
in

gine-General
.
The

Thermostat
Quick
Check
In
later
models,
the
ECT
sensor
and
the
gauge

are
combined
into
one

unit
.
For

refer
to
Table

To
check
if
the
thermostat
is
opening
and
coolant
is
circulat-
ing
through
the
radiator,
allow
a
cold
engine
to
reach
operat-
ing
temperature
(temperature

centered)
.
Shut
off
engine
.
Feel
the
top
radiator
hose
.
If
the
hose
is
hot
to
the
touch,
the
coolant
is
probably
circulating
cor-
rectly
.
If
there
are
any
cool
areas
in
the
hose
or
radiator,
cool-
ant
flow
to
the
radiator
is
probably
restricted
.
Check
for
a
faulty
thermostat
or
aplugged
radiator
.
NOTE-
A
thermostat
that
is
stuck
open
will
cause
the
engine
to
warmup
slowly
and
run
belownormal

at
highway
speed
.
A
thermostat
that
is
stuck
closed
will
re-
strict

and
cause
overheating

GENERAL
The
exhaust
system
is
designed
to
be
maintenance
free,
al-
though
regular
inspection
is
warranted
due
to
the
harsh
oper-
atingconditions
.
Under
normal
conditions,
the
catalytic
converter
does
not
require
replacement
unless
it
is
damaged
.
On
1996
and
later
cars,
a
pre-
and
post-catalytic
converter
oxygen
sensor
is
used
at
each
catalytic
converter
.
Be
sure
to
take
care
when
removingthe
system
not
to
damage

.
NOTE-
OnM52

two
resonator
pípes
(short
and
long)
are
incorporated
into
the
rear

assembly
.

.
An
exhaust
flap
is
integrated
into
the
outlet
side
of
the
short

.
The
flap
is
operated
by
a
vacuum

tuator

control
mod-
ule)
.
The
flap
is
closed
at
engine
speeds
below
2,500
rpm
.
This
allows
exhaust
gasses
to
flow
through
the
long
resonator
pipe
and
reduce
noise
.
Above
2,500rpm,
the
exhaust
flap
is
open
(no
vacuum
applied
to
the
actuator)
and
allows
exhaust
gasses
to
flow
through
the
short
pipe
for
maximum
performance

The
E36

are
equipped
with
a
sophisticated
centralized

electric/electronics
plan
.
The
system
is
self-diagnostic
and
incorporates
many
functions
into

.
The
consolidation
of
several
systems
into
a

minimizes
power
requirements
and
the
incorporation
of
the

results
in
more

.

system
regardless

whether
the
vehi-
cle

or
an
On-Board

.
Two
types
of

systems
were
installed,
de-
pending
on

production
date
.
On
the
early
system
(model
year
1994
up
to
January
1995),
the
ignition

fuel
injection
functions
are
disabled
whenever
the
vehicle
is
locked
in
the
double

mode
.
This
is
referred
lo
as
EWS
or
EWS
I
.
Beginning
in
January
1995,
the
driveaway
protection
sys-
tem
was
upgraded
to
a
more
sophisticated
system,
called
EWS
