engine Oldsmobile Achieva 1995 s Repair Manual

Check the fluid level only when your engine is off, the
vehicle
is parked on a level place and the transaxle is
cool enough for you to rest your fingers on the transaxle
case.
Then, follow these steps:
1. Flip the handle up and then pull out the dipstick and
clean
it with a rag or paper towel.
2. Push it back in all the way and remove it.
3. Check both sides of the dipstick and read the lower
level. The fluid level must be between the ADD and
FULL marks. (Note: Fluid may appear at the bottom
of the dipstick even when the fluid level is several
pints low.)
4. If the fluid level is where it should be, push the
dipstick back in all the way and flip the handle
down.
If the fluid level is low, add more fluid as
described
in the next steps.
How to Add Fluid
Here’s how to add fluid. Refer to the Maintenance
Schedule
to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants’’
in the Index.
1. Remove the dipstick by flipping the handle up and
then pulling the dipstick out.
2. Add fluid at the dipstick hole.
Add only enough fluid
to bring the fluid level up to
the FULL mark
on the dipstick.
3. Push the dipstick back in all the way; then flip the
handle down to lock the dipstick
in place.

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.
6-21

What to Use
Use a mixture of one-half clearz water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 182SM,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825M with a complete coolant flush
and refill. Use
GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill.
If you use
this mixture, you don’t need to add anything else.
I
I NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cast 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.
6-22

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

LEVEL

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.
6-24

What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part No.
1052535). Use new brake fluid from a sealed container
only, and always clean the brake fluid reservoir cap
before removing it.
Brake Wear
Your Oldsmobile has front disc brakes and rear drum
brakes.
Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads
are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving
(except when you are pushing on the brake pedal
firmly). NOTICE:
0 Don’t let someone put in the wrong kind of
fluid. For example, just a few drops of
mineral-based oil, such as engine oil, in
your brake system can damage brake
system parts
so badly that they’ll have to be
replaced.
Brake fluid can damage paint, so be careful
not to spill brake fluid on your vehicle.
If
you do, wash it off immediately. See
“Appearance Care” in the Index.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
