radiator cap Oldsmobile Achieva 1995 Owner's Manuals

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

NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So use the recommended coolant.
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.
5-17

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

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.

Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
To Add
Open the cap labeled
WASHER
FLUID OmY.
Add washer fluid until the
tank is full.
NOTICE:

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
3/4 full
when it’s very cold. This allows for
expansion, 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.
