radiator cap Oldsmobile Aurora 1997 Owner's Manuals

1. You can remove the coolant surge tank pressure cap
when the cooling system,-including the coolant surge
tank pressure cap and upper radiator hose, is
no
longer hot. Turn the pressure cap slowly about
one-quarter
turn to the left and then stop.
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap slowly, and
remove it.

3. Then fill the coolant surge tank with the proper mix,
up to FULL COLD. 4. With the coolant surge tank pressure cap off, start the
engine and let
it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine fans.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more of the proper mix to the coolant surge tank
until the level reaches FULL COLD.
5-22

A CAUTION:
'hrning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn
you badly.
Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the
FULL COLD mark or a little higher.

If the message LOW ENGINE COOLANT is displayed
on your message center,
it means you’re low on
engine coolant.
Adding Coolant
If you need more coolant, add the proper DEX-COOL’
coolant mixture
at the surge tank, but only when the
engine is cool.
I A CAUTION: I
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.
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.

Open the cap labeled WASHER FLUID ONLY. Add

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system.
Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only
three-quarters full when it’s very cold. This
allows for expansion if freezing occurs,
which could damage the tank if it
is
completely full.
Don’t use radiator antifreeze in your
windshield washer.
It can damage your
washer system and paint.
Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
