1993 OLDSMOBILE SILHOUETTE coolant level

Engine Overheating (CONTI)
The coolant level should be at or above
the
FULL HOT mark. If it isn’t, you
may have a leak in the radiator hoses,
heater hoses, radiator, water pump or
somewhere else in the cooling system.
I, rn Heater and radiator hoses, and
b other engine parts, can be
VGI~ hot. Don’t touch them. If you
do, you can be
burned.
Don’t run the engine if there is a
leak. If you
run the engine, it
could lose all coolant. That could
cause an engine fire, and you
cou
be burned. Get any leak fix
before you drive the vehicle Engine damage from running your
: engine without coolant isn’t
i.: covered
by your warranty.
If there seems to be no leak, check to
see if the electric engine fan(s) is
running. If the engine is overheating, the
fan(s) should be running. If it isn’t, your
vehicle needs service.
How to Add Coolant to the Coolant
Recovery
Tank:
If you haven’t found a problem yet, but
the coolant level isn’t at or above the
FULL HOT mark, add a 50/50 mixture
of
clean water (preferably distilled) and
a proper antifreeze at the coolant
recovery
tank. (See the Index under
Coolant for more information about the
proper coolant mix.)

mix through the filler neck
until the level reaches the base
of the
filler neck.
8. Then replace the pressure cap. Be

Radiator Pressure Cap
(105 kPa) pressure-type cap and
must be tightly installed to prevent

coolant loss and possible engine +-
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube on
the radiator
filler neck.
When
you replace your radiator pressure
cap, an
AC@ cap is recommended.
Thermostat
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.
When
you replace your thermostat, an
AC@ thermostat is recommended.
Power Steering Fluid
How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap
and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
When the engine compartment is hot,
the level should be at the
