engine Oldsmobile Achieva 1998 s Service Manual

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and
it keeps the
battery charged. You will need
a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you
feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can.
To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.
Recreational Vehicle Towing
There may be times when you want to tow your vehicle
behind another vehicle for use at your destination. Be sure
to use the proper towing equipment designed for
recreational towing. Follow the instructions for the
towing equipment.
Towing Your Vehicle from the Front
Follow these steps:
1. Put the front wheels on a dolly.
NOTICE:
Do not tow your vehicle with the front wheels in
contact with the ground, or the automatic
transaxle could be damaged.

Towing a Trailer
L
If you don’t use the correct equipment and drive
properly, you can lose control when you pull a
trailer.
For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
You may also damage your vehicle; the resulting
repairs would not be covered by your warranty.
Pull
a trailer only if you have followed all the
steps in this section. Ask your retailer for advice
and information about towing a trailer with
your vehicle.
Do not tow a trailer if your vehicle is equipped with a
2.4L (Code T) engine. Your
vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment.
To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in “Weight of the Trailer”
that appears later in this section. But trailering
is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.
That’s the reason for this part. In
it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that
of
your passengers. So please read this section carefully
before you pull a trailer.
Load-pulling components such as the engine, transaxle,
wheel assemblies and tires are forced to work harder
against the drag of the added weight. The engine is
required to operate at relatively higher speeds and under
greater loads, generating extra heat. What’s more, the
trailer adds considerably to wind resistance, increasing
the pulling requirements.

If You Do Decide To Pull A Trailer

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your
rig will be legal, not only where you live but
also where you’ll be driving. A good source for this
information can be state or provincial police.
Consider using a sway control. You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during the first
1,000 miles
(1
600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h) and
don’t make starts at full throttle. This helps your
engine and other parts
of your vehicle wear in at the
heavier loads.
Obey speed limit restrictions when towing a trailer.
Don’t drive faster than the maximum posted speed
for trailers (or no more than 55 mph (90 km/h)) to
save wear on your
v icle’s parts. Three
important considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
0 and the total weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
1,000 lbs. (450 kg). But
even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull a
trailer are all important. And, it can also depend on any
special equipment that you have on your vehicle.

Making Turns
~ ~~ .-.
NOTICE:
Making very sharp turns while trailering could
cause
the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
The green arrows on your instrument panel will flash
whenever
you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your instrument panel will flash for turns even if the bulbs on
the trailer
are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, use the highest gear possible. If
you cannot maintain posted speeds, driving at a lower speed may help avoid overheating your engine
and transaxle.

Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do
it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK
(P) yet.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK
(P).
Release the regular brakes.
When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you
start
your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating’’
in the Index.
Towing A Trailer
(Except 3100 Engine)
Your vehicle is neither designed nor intended to tow
a trailer.

2. Get the vehicles close enough so the jumper cables
can reach, but
be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Set the parking brake
firmly on each vehicle. Put an automatic transaxle in
PARK (P) before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet.
Turn off all
lamps that aren’t needed, as well
as radios. This will
avoid
sparks and help save both batteries. In
addition, it could save your radio.
I NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries.
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
5. Find the positive (+) and negative (-) terminals on
each battery.
5-4

A
L CAUTI-N:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You don’t
need to add water to the
AC Delco Freedom’
battery installed in every new
GM vehicle. But
if a battery has filler caps, be sure the right
amount of fluid is there.
If it is low, add water to
take care of that first.
If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
6. Check that the jumper cables don’t have loose or
missing insulation. If they do, you could get a shock.
The vehicles could be damaged, too. Before you
connect the cables, here
are some things you should
know. Positive
(+) will go to positive (+) and
negative
(-) will go to a metal engine part. Don’t
connect positive
(+) to negative (-) or you’ll get a
short that would damage the battery and maybe other
parts, too.
1 CAUT’*Y:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.

9. Now connect the black
negative
(-) cable to
the good battery’s
negative
(-) terminal.
Don’t let the other end
touch anything until
the next step. The other
end
of the negative
cable
doesn ’t go to
the dead battery.
It goes to a heavy unpainted metal part
on the engine of
the vehicle with the dead battery.
10.
11.
12.
13.
Attach the cable at least 18 inches (45 cm) away from
the dead battery, but not near engine parts that move.
The electrical connection is just as good there, but the
chance of sparks getting back to the battery is much less.
Now start the vehicle with the good battery and run
the engine for a while.
Try to start the vehicle with the dead battery. If it
won’t
start after a few tries, it probably needs service.
Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.
