This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is too

vehicle or
go off the road. Check your washer fluid level
often.

2. Attach a separate chain
to each side of the axle
inboard of the spring.
Engine Overheating
You will find a coolant temperature gage on your
Oldsmobile's instrument panel. See "Coolant
Temperature Gage" in the Index.
You will also find a
low coolant level warning light on
your Oldsmobile's
instrument panel.
If Steam Is Coming From Your Engine

The coolant level should be at or above FULL COLD. 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.
r
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on 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 Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD, add a 50/50 mixture of clean
water (preferably distilled) and a proper antifreeze at the
coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap,
is cool
before you do it.
(See “Engine Coolant” in the Index for
more information about the proper coolant mix.)
5-15

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
fan.
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, or just above
the small cylinder at the base
of the opening.
5. Then replace the pressure cap. Be sure the pressure
cap is tight.
5-19

Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir
is
filled with hydraulic clutch fluid.
It isn’t a good idea to “top off’ your clutch fluid. Adding
fluid won’t correct
a leak.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
Refer to the Maintenance
Schedule to determine how
often you should check the
fluid level in your clutch
master cylinder reservoir
and for the proper fluid. See
“Owner Checks and
Services” and
“Recommended Fluids and
Lubricants” in the Index.
How to Check
If you can see fluid in the reservoir, the level is
acceptable.
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 Oldsmobile will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F ( 128 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.

To Check Coolant
When your engine is cold, the coolant level should be at
the FULL COLD mark,

If this light comes on,
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.
Surge Tank Pressure Cap
NOTICE:
Your pressure cap is an 18 psi (124 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating.
%%en you replace your surge tank pressure cap, a GM
cap is recommended.
6-23

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
p .w ii
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.
What to Add
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants”
in the Index.
I NOTICE:
When adding power steering fluid or making a
complete fluid change, always use the proper
fluid. Failure to use the proper fluid can cause
leaks and damage hoses and seals.

Part B: Owner Checks and Services
Listed below are owner checks and services which
should be performed at the intervals specified to help
ensure the safety, dependability and emission control
performance
of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
in
Part D.
At Each Fuel Fill
Engine Oil Level
Check the engine oil level and add t,he proper oil if
necessary. See “Engine Oil” in the Index for further
details.
Engine Coolant Level
Check the engine coolant level and add the proper
coolant mix if necessary. See “Coolant” in the Index for
further details.
Windshield Washer Fluid Level
Check the windshield washer tluid level in the
windshield washer tank and add the proper tluid if
necessary. See “Windshield Washer Fluid”
in the Index
for further details.
At Least Once a Month
Tire Inflation
Check tire inflation. Make sure tires are inflated to the
pressures specified
on the Tire-Loading Information
label located
on the rear edge of the driver’s door. See
“Tires”
in the Index for further details.
Cassette Deck
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.
