engine coolant Oldsmobile Aurora 1998 s Owner's Guide

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 driver information 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.
6-24

A CAUTION:
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, a GM thermostat
is recommended.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak
in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.

Adding Washer Fluid
There are two windshield washer fluid tanks. The upper
tank (shown above) will empty first. When the lower
tank contains
0.5 quarts (0.5 liters) or less, the message
LOW WASHER
FLUID will be displayed on the Driver
Information Center.
Open the cap labeled WASHER
FLUID ONLY. Add
washer fluid until the tank
is full.

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 engine coolant (antifreeze) in
your windshield washer.
It can damage
your washer system and paint.
