belt BUICK PARK AVENUE 1994 Service Manual

3800 Supercharged (L67) Engine
(Option)
Your Park Avenue Ultra has a 3800 Supercharged
engine. Buick chose supercharging rather than
turbocharging because Buick emphasizes smooth,
refined power.
The Supercharger is a device which is designed to pump
more air into the engine than it would normally use.
This air mixed with fuel, creates increased engine
power. Since
the Supercharger is a pump and is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
The powertrain control module (PCM), works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling and light throttle cruising, the excess air that the
Supercharger is pumping
is routed through a bypass. All
of these controls, working together provide high
performance character and
fuel efficiency in the 3800
V6 Supercharged Buick engine.
The power steering pump uses a remote reservoir
mounted on the throttle and cruise control cable bracket.
See “Maintenance Schedule’’ in
the Index for when you
should check the fluid.
Engine Accessory Belt
The Supercharged 3800 engine uses two accessory drive
belts. One belt drives the generator and the power
steering pump. The second belt drives the supercharger,
coolant pump and air conditioning compressor. Each
belt has its own tensioner and idler pulley.

The tire has a puncture, cut, or other damage that
can’t be repaired well because
of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones
with that same TPC Spec number. That way,
your vehicle
will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number
will be followed by a “MS”
(for mud and snow).
If you ever replace your tires
with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires by
treadwear, traction and temperature performance.
(This
applies only to vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate
of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire

0 For stubborn stains, use a mild solution of 10%
isopropyl alcohol (rubbing alcohol) and
90% water.
0 Never use oils, varnishes, solvent-based or abrasive
cleaners, furniture polish or shoe polish on leather.
Soiled leather should be cleaned immediately. If dirt
is allowed to work into finish,
it can harm the
leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections
in the windshield
and even make
it difficult to see through the windshield
under certain conditions.
Cleaning Speaker Covers
Vacuum around a speaker cover gently, so that the
speaker won’t be damaged. If something gets on one of
them, follow the steps earlier under “Using
Solvent-Type Cleaner on Fabric.” Use as little solvent as
you can.
Care of Safety Belts
Keep belts clean and dry.
Glass
Glass should be cleaned often. GM Glass Cleaner (GM
Part
No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films.
Don’t use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped off later. If
abrasive cleaners are used on the inside
of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.

Explanation of Scheduled Maintenance
Services
Following 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 SH
or SG Energy Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may be shown alone
or
in combination with others, such as “SH/CD” or
“SH,
SG, CD,” “SG/CD,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g., SAE
5W-30 or SAE low-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
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.
3. 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.
4. Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
5. 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.

Section C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall). You should let your GM dealer’s
service department or other qualified service center
do
these jobs. Make sure any necessary repairs are
completed at once.
INSPECTION
OR SERVICE
Restraint System
WHAT SHOULD BE DONE
Now and then, make sure all your belts,
buckles, latch plates, retractors,
anchorages and reminder systems are
working properly. Look for any loose
parts or damage. If you see anything
that might keep a restraint system from
doing its job, have it repaired.
I
INSPECTION
OR SERVICE I WHAT SHOULD BE DONE I
Steering, Suspen-
sion and Front-
Wheel-Drive Axle Boot and Seal In-
spection Inspect the
front and rear suspension
and steering system for damaged, loose
or missing parts, signs of wear, or lack
of lubrication. Inspect the power steer-
ing lines and hoses for proper hookup,
binding, leaks, cracks, chafing, etc.
Clean and then inspect the drive axle
boot seals
for damage, tears or leakage.
Replace seals if necessary.
Exhaust System
Inspection Inspect
the complete exhaust system.
Inspect the body near the exhaust
system. Look for broken, damaged,
missing or out-of-position parts as
well
as open seams, holes, loose
connections, or other conditions which
could cause a heat build-up in the floor
pan or could let exhaust fumes into the
vehicle. See “Engine Exhaust” in the
Index.
Throttle Linkage Inspect the throttle linkage for
Inspection interference or binding, and for
damaged or missing parts. Replace
parts as needed.
