engine CHEVROLET VENTURE 1998 Service Manual

Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful. Snow can
trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you.
You can’t see it or smell it, so you might not
know it is in your vehicle. Clear
away snow from
around the base of your vehicle, especially any
that
is blocking your exhaust pipe. And check
around again from time
to time to be sure snow
doesn’t collect there.
Open
a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep
CO out.

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.

Towing a Trailer
A CAUTION:
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.
Pull
a trailer only if you have followed all the
steps in this section.
Ask your dealer for advice
and informatinn about towing a trailer with
your vehicl-
NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this
part, and see your dealer for
important information about towing a trailer
with your vehicle. Your
vehicle can tow a trailer.
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 section. 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.

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 if your trailer will
weigh
2,000 lbs. (900 kg) or less. You should always
use a sway control if your trailer will weigh more
than
2,000 lbs. (900 kg). You can ask a hitch dealer
about sway controls.
Don’t tow a trailer at
all during the first 500 miles
(800 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 kmh) and
don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at the
heavier loads.
You should use THIRD
(3) (or, as you need to, a
lower gear) when towing a trailer. Operating your
vehicle in THIRD
(3) when towing a trailer will
minimize heat buildup and extend the life
of
your transaxle. Three important considerations have to
do with weight:
the weight of the trailer,
the weight
of the trailer tongue
0 and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,400 lbs. (630 kg)
with up to
six occupants or more than 2,000 lbs.
(900 kg) with up to two occupants. If you have the
optional trailer towing package, your vehicle can tow up
to
2,900 lbs. (1 300 kg) with up to six occupants or up to
3,500 lbs. (1 575 kg) with up to two occupants. 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.

Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer
so that the tongue wdl not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching safety
chains and
do not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Driving with a Trailer
Trailer Brakes
If your trailer weighs more than 1,000 lbs. (450 kg)
loaded, then it needs its own brakes
-- and they must be
adequate. Be sure to read and
follow the instructions for
the trailer brakes
so you’ll be able to install, adjust and
maintain them properly.
Because you have anti-lock brakes, do not
try to tap into
your vehicle’s brake system.
If you do, both brake
systems won’t
work well, or at all.
A CAUTION:
If you have a rearmost window open and you
pull a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can’t see
or smell CO. It can cause unconsciousness or
death.
(See “Engine Exhaust” in the Index.) To
maximize your safety when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
0 Keep the rearmost windows closed.
0 If exhaust does come into your vehicle
through a window in the rear or another
opening, drive
with your front, main
heating or cooling system on and with the
fan on any speed. This
will bring fresh,
outside
air into your vehicle. Do not use
RECIRC because
it only recirculates the
air inside your vehicle. (See “Comfort
Controls’’ in the Index.)

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, shift down and reduce your
speed to around
45 mph (70 kmih) to reduce the
possibility of engine and transaxle overheating.
If you are towing a trailer that weighs more than
1,000 lbs. (450 kg), you may prefer to drive in
THIRD
(3) instead of AUTOMATIC OVERDRIVE (D)
(or, as you need to, a lower gear). This will minimize
heat build-up and extend the life
of your 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. Apply your regular brakes, but don’t shift into
PARK (P) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK (P).
5. 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 thc .ailer
is clear of the chocks.
4. Stop and have son --- 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, belts, 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.

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.
I NOTICE:
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles
involved in the jump
start procedure. Put an
automatic transaxle in PARK
(P).
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
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!
4. Open the hoods and locate the batteries. Find
the positive
(+) and negative (-) terminals on
each battery.
I 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.

is running.
5. Connect the red positive (+) cable to the positive (+)
terminal of the vehicle with the dead battery. Use a
remote positive
(+) terminal if the vehicle has one.
6. Don’t let the other end
touch metal. Connect it
to the positive
(+)
terminal of the good
battery. Use a remote
positive
(+) terminal if
the vehicle has one.

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 1 go
to the dead battery. It goes to a heavy unpainted metal
part on the engine
of the vehicle with the dead battery.
