1995 OLDSMOBILE AURORA coolant

Engine Coolant
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Aurora will:
0 Give freezing protection down to -34°F (-37°C)
0 Give boiling protection up to 262°F (128°C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use
Use a mixture of one-half c.lt.crr~ wwtor (preferably
distilled) and one-half antifreeze that meets “GM
Specification 182S-M,” which won‘t damage aluminum
parts.
You call also use a recycled coolant conforming to
GM Specification 1825-M
with a complete coolant tlush
and refill. Use GM Engine Coolant Supplement (sealer)
with any cotnplete coolant flush and refill. If you use
this mixture, you don‘t need to add anything else.
A
special procedure is required for adding sealer; see the
ALI~o~~ Service Manual. (To order a service 1nanual. see
”Service Publications“
in the Index.)

NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
Adding Coolant
The engine coolant
surge tank is located
on the driver’s side
of
the engine
compartment.
To Check Coolant
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.

To Add Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
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.
Power Steering Fluid
How To Check Power Steering Fluid
When the engine compartment is cool, 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.
The level should be at the
FULL COLD mark. Add
enough fluid to bring the level up to the mark.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
