1993 PONTIAC GRAND-PRIX coolant level

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
A
Heater and radiator hoses,
and other
engine parts, can
be very hot. Don’t touch them. If
you do, you can be burned.
Don’$ 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 vou drive the vehicle.
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 about the proper
coolant mix.)

Adding only plain water to
your cooling system
can be
dangerous. Plain water,
or some I
other liquid like alcohol, can boil
before the proper coolant
mix will.
Your vehicle’s coolant warning
system
is set for the proper coolant
mix. With plain water or the wrong
mix, your engine could get too hot
but you wouldn’t get the overheat
warning. Your engine could catch

you or others could be
burned. Use a

level should be up to
HOT or a little
higher.
If this light comes on, it means you’re
low on engine coolant.
