Adding Coolant
If
you need more coolant, add
the
proper
DEX-COOL@
coolant mixture
at the
surge
tmk,
but
only
when the
engine is cool.
You can be burned if you
spill
coolant
on
hot
engine parts. Coolant contains ethylene
glycol,
and
it
will burn
if
the engine parts are hot
enough.
Don’t
spill coolant on a hot engine.
When replacing the pressure cap, make sure
it
is
tight.
The
surge tank cap
is
a
I§
psi
(105
ma)
pressure-type
cap
and
must
be
tightly installed
to
prevent coolant
loss
and
possible
engine
damage from overheating. Be
sure
the arrows
If
the
surge tank pressure cap needs to be replaced,
a
General Motors cap
is
recommended.
e
Engine coolant temperature
is
controlled
by
a thermostat
in the engine coolant system. The thermostat stops the
flow
of
coolant through the radiator until
the
coolant
reaches a preset temperature.
If
your thermostat needs to be replaced, a General
Motors
thermostat
is
recommended.
