1993 BUICK LESABRE torque

In World War 11, Buick built aircraft engines, tanks and
other military hardware. This post-war period brought
great styling and engineering changes which resulted in
increased sales. The torque converter automatic
transmission, Dynaflow, was introduced in the 1948
Roadmaster. Buick’s famous “portholes” came along in
1949.

A high-compression V-8 engine was introduced in 1953.
And Buick’s famous vertical pillar “toothy” grille
(introduced in 1942), became more massive in the
post-war era.

If there is no curb when you’re parking uphill, turn the
wheels to the right.
If there
is no curb when you’re parking uphill on the left
side of a one-way street, your wheels should be turned
to the left.
Torque Lock (Automatic Transaxle)
If you are parking on a hill and you don’t shift your
transaxle into
“F”’ (Park) properly, the weight of the
vehicle may put too much force
on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever out of
“P’ (Park). This is called “torque lock.” To
prevent torque lock, always be sure to shift into “P’
(Park) properly before you leave the driver’s seat. To
find out how, see “ Shifting Into ’P’ (Park)” in the
Index.
When you are ready to drive, move the shift lever out of
“P” (Park)
BEFORE you release the parking brake.
If “torque lock” does occur,
you may need to have
another vehicle push yours a little uphill to take some
of
the pressure from the transaxle, so you can pull the shift
lever
out of “P” (Park).

/I CAUTION:
Incorrect wheel nuts or improperly tlghtened
wheel nuts
can cause-the wheel to become loose
and even’come
off. This could lead to an
acclelent. Be sure to use the correct wheel nuts.
If you have to replace them, be sure to get the
right kind.
Stop somewhere
as soon as you can and have
the nuts tightened with a torque wrench to 100 ft.
Ibs. (1 40 Nmm).
Don’t try to put a wheel cover on your compact spare
tire. It won’t fit. Store the wheel cover in
the trunk until
you have the flat tire repaired or replaced.
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.
Now secure all the equipment back into the trunk
storage area.
I /WRENCH
&!b, CAUTION:
I
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop
or collision, loose
equipment could strike someone. Store
all these
in the proper place.

Tire Inspection and Rotation
To make your tires last longer, have them inspected and
rotated at the mileages recommended in the
.
Maintenance Schedule. See “Scheduled Maintenance
Services’’ in the Index.
Use this rotation pattern. After
the tires have been rotated, adjust the front and
rear inflation pressure as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the
Index.
I
A CAUTION:
Rust or dlrt on a wheel, or on the parts to which
it is fastetfed, can make wheel nuts become
loose after a time. The wheel could come off and
cause
an accident. When you change a wheel,
remove any rust or dirt from places where the
wheel attaches
to the vehicle. In an emergency,
you can use a cloth or a paper towel to do this;
but be
sure to use a scraper or wire brush later, if
you need to, to get all the rust or dirt off. (See
“Changing a FI; Tire’* On the Index.)

Scheduled Maintenance Services Schedule I
Follow Schedule I if your car is MAINLY driven under one .or more of the following conditions:
When most trips are less than 4 miles (6 kilometers).
When most trips are less than 10 miles (16 kilometers) and outside temperatures remain below freezing.
When most trips include extended idling and/or frequent low-speed operation as in stop-and-go traffic.
Towing a trailer.*?
When operating in dusty areas.
Schedule I should also be followed if the car is used for delivery service, police, taxi or other commercial applications.

Explanation of Scheduled Maintenance
Services
Below are explanations of the services listed in Schedule
I and Schedule 11.
The proper fluids and lubricants to use are listed in
Section
D. Make sure whoever services your vehicle
uses these. All parts should be replaced and all
necessary repairs done before
you or anyone else drives
the vehicle.
1. Engine Oil and Filter Change* -- Always use SG
Energy Conserving I1 oils of proper viscosity. The
“SG” designation may be shown alone or in
combination with others, such as “SG/CC”,
“SG/CD” or “SF, SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE
5W-30 or SAE 10W-30), see “Engine Oil” in
the Index. If your vehicle has an Engine Oil Life
Monitor, the monitor will show
you when to change
the oil. See “Engine Oil Life Monitor” in the Index.
2. Chassis Lubrication -- Lubricate suspension and
steering linkage. Lubricate the transaxle shift linkage, and parking brake
cable guides, underbody
contact points and linkage.
3. Throttle Body Mounting Bolt Torque* -- Check
the torque of the mounting bolts and/or nuts.
4. Tire and Wheel Rotation and Inspection -- For
proper wear and maximum tire life, rotate your tires
following
the instructions in this manual. See “Tires,
Inspection
& Rotation” in the Index. Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check the wheel alignment. Check
for damaged wheels also.
5. Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
6. Cooling System Service” -- Drain, flush and refill
the system with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See
“Coolant” in
the Index. This provides proper freeze
protection, corrosion inhibitor level
and engine
operating temperature.
* An Emission Control Service.
3‘ The U.S. Environmental Protection Agency has determined that the failure to perfonn this maintenance item will not nullify the emission warranty or limit recall liability prior to thecompletion of vehicle
useful life. General Motors, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in “Section E:Maintenance Record”.
