1993 BUICK PARK AVENUE wheel torque

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
“P” (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 “F‘” (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).

Lower the vehicle by rotating the wheel wrench
counterclockwise. Lower the jack completely. Tighten the wheel nuts
firmly
in a criss-cross
sequence
as shown.
[ A CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come off. This could lead to an
accident. 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.

When to Check: Check your tires once a month or
more.
Don’t forget your compact spare tire. It should be at
60
psi (420 Ha).
How to Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking
at the tires will not
tell you the pressure, especially
if you have radial tires --
which may look properly inflated even if they’re
underinflated.
i
If your tires have valve caps, be sure to put them back
on. They help prevent leaks by keeping out dirt and
moisture.
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.

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.
NOTE: To determine your engine’s displacement and
code, see “Engine Identification” in the Index.
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.
* An Emission Control Service.

Chassis Lubrication -- Lubricate the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is
equipped with grease fittings, lubricate the
suspension and steering linkage.
Throttle Body Mounting Bolt Torque” -- Check
the torque
of the mounting bolts and/or nuts.
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.
Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
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.
The U.S. Environmental Protection Agency has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion 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”.
