1994 BUICK CENTURY engine

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
If you do, here are some important points.
There are many different laws having to do with
trailering. Make sure your rig will be legal, not on!y
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 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
0 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 vehicle’s parts.
Three important considerations have to do
with weight:
Weight of the Trailer
Your vehicle can tow normally up to 1,000 pounds
(450kg). If your vehicle has a
3100 V6 engine with a
four-speed automatic transaxle and is equipped with the
optional heavy-duty engine cooling system,
it can tow
up to 2,000 pounds (900 kg).
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.

Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to
your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left.
To move the trailer to the right, move your
hand to the right. Always back up slowly and,
if
possible, have someone guide you.
Making Turns
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
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green arrows
on your instrument panel
will flash whenever
you signal
a turn or lane change. Properly hooked up,
the trailer lights
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, shift down and reduce your
speed to around 45
mph (70 km/h) to reduce the
possibility
of engine and transaxle overheating.
If you are towing a trailer that weighs more than 1,000
pounds (450
kg) and you have an automatic transaxle
with Overdrive, you may prefer to drive in “D” instead
of Overdrive.
An overdrive transmission is required if
towing a trailer more than 1,000 pounds (450 kg).

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
“P”
(Park) 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
“P” (Park).
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 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.

Before you connect the cables, here are some basic things
you should know. Positive (+) will go to positive (+) and
negative
(-) will go to negative (-) or a metal engine part.
Don’t connect
(+) to (-) or you’ll get a short that would
damage the battery and maybe other parts, too.
5. 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.

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.
9. 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.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle with the dead battery. If it
won’t start after
a few tries, it probably needs
service.
12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.

2. Position a 4" x 4" wood beam across sling chains
with spacer blocks contacting the forward extensions
of the engine cradle.
3. Position the lower sling crossbar halfway between
the timber and the lower edge of the fascia.

Engine Overheating
You will find a coolant temperature gage or the warning
light about a hot engine on
your Buick’s instrument
panel.
If Steam Is Coming From Your Engine
I NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when
you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
