1993 Oldsmobile Cutlass Supreme heater

Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
If the coolant inside the coolant
recovery tank is boiling, don’t do
anything else until it cools down. The
coolant level should be at or above
the
COLD 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.

CAUTION I
Heater and radiator hoses,
and other engine parts, can
1;, ;cry 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 could be
burned. Get any leak fixed before
I
you drive the vehicle.
I
If there seems to be no leak, check to
see
if the electric engine fan is running.
If the engine is overheating, the fan
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
COLD, add a
50/50 mixture of clean
water (preferably distilled) and a proper
antifreeze at the coolant recovery
tank.
(See the Index under Engine Coolant
for more information abaut the proper
coolant
mix.)

3. After the engine cools, open the
coolant air bleed valve or valves.
3.1L V6 (VIN Code T or M): There
are two bleed valves. They are located
on the thermostat housing and the
thermostat bypass tube.
3.4L V6 (VIN Code X): There are
two bleed valves. They are located on
the thermostat housing and the
heater inlet pipe. 4. Fill the radiator with the proper mix,
up to the base of the filler neck.
If you see a stream of coolant coming
from
an air bleed valve, close the valve.
Otherwise, close the valve(s) after the
radiator is filled.
5. Rinse or wipe any spilled coolant
from the engine and compartment.

If none of them is true, change the oil
every
7,500 miles (12 500 km) or 12
months-whichever comes first.
Change the filter at the first oil change
An engine block heater can be a big
help
if you have to park outside in v
