1997 Oldsmobile Achieva check engine

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.
If you have to add coolant more than four times a yea,
have your retailer check your cooling system.
I NOTICE:
If you use the proper coolant, you don't have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
The surge tank is located on the passenger's side of the
engine compartment.
6-26

Surge Tank Pressure Cap
NOTICE: ~
Your pressure cap is an 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating.
When y'6u &place your surge tank pressure cap,
a
GM cap is recommended.
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
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.

How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then 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
C mark. If necessary, add only
enough fluid to bring the level up to the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” in the Index. 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.
Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid
until the tank is full.

Vehicle Identification Number (VIN)
c
i
bl SAMPLE4UXVM072675 kd I1
This is the legal identifier for your Oldsmobile. It
appears on a plate in the front corner of the instrument
panel, on the driver’s side.
You can see it if you look
through the windshield from outside your vehicle.
The VIN also appears
on the Vehicle Certification
and Service Parts labels and the certificates
of title
and registration.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.
Service Parts T -entification Label
You’ll find this label on the bottom of your spare. tire
cover. It’s very helpful
if you ever need to order parts.
On this label
is:
0 your VIN,
0 the model designation,
0 paint information and
a list of all production options and
special equipment.
Be sure that this label
is not removed from the vehicle.
Electrical System
Add-on Electrical Equipment
NOTICE: --
Don’t add anything electrical to your Oldsmobile
unless you check with your retailer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical
to your Oldsmobile, see “Servicing
Your Air Bag-Equipped Oldsmobile”
in the Index.

Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the fuse block. An electrical overload will cause the
lamps to
go on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by an internal
circuit breaker and a fuse.
If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload
is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is
too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by
a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself. This
greatly reduces the chance
of fires caused by
electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with
a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can “borrow” one that has the same
amperage. Just pick a feature of your vehicle that you
can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
There are two fuse blocks in your vehicle: the
instrument panel fuse block
and the engine compartment
fuse block.

Part B: Owner Checks and Services
Listed below are owner checks and services which
should be performed at the intervals specified to help
