injure you even when the engine is not running.
Keep hands, clothing and tools away from any
I underhood electric fan. I
A CAUTION:

Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill
things that will burn onto
a hot engine.

Before closing the hood, be sure all the filler caps are on
properly. Then just pull the hood down and close it
firmly.
3800 V6 Supercharged Engine
Your Park Avenue Ultra has a 3800 V6 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.
250
ProCarManuals.com

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.
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. See
“Maintenance Schedule’’ in the Index for when you
should check the accessory drive belts and supercharger
oil level. Have your dealer check the oil level in the
supercharger.
Engine Oil
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick is
directly behind the engine
fan. Turn
off the engine and
give the oil a few minutes
to get back down into the
oil pan. If you don’t, the oil
dipstick might not &ow the
actual level.

Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the radiator and air
conditioning condenser. Wash the pressure cap and
neck.
To help ensure proper operation, we recommend a
pressure test of both the cooling system and the
pressure cap.
7. Transaxle Service -- Change both the fluid and
filter every 15,000 miles (25
000 km) if the vehicle
is mainly driven under
one or more of these
conditions:
In heavy city traffic where the outside
temperature regularly reaches
90 OF (32 “C) or
higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police car or delivery
If you do
not use your vehicle under any of these
conditions, change both the fluid and filter every
100,000 miles
( 160 000 km).
service.
8. Spark
Plug Replacement* -- Replace spark plugs
with the proper type. See “Specifications Chart” in
the Index.
9. Spark Plug Wire Inspection*? -- Inspect for
burns, cracks or other damage. Check the boot fit at
the distributor and at the spark plugs. Replace wires
as needed.
10.
Air Cleaner Filter Replacement* -- Replace every
30,000 miles (50 000 km) or more often under dusty
conditions. Ask your dealer for the proper
replacement intervals for your driving conditions.
11.
Fuel Tank, Cap and Lines Inspection*? -- Inspect
fuel tank, cap and lines (including
fuel rails and
injection assembly) for damage or leaks. Inspect fuel
cap gasket for an even filler neck imprint or any
damage. Replace parts as needed. Periodic
replacement of the fuel filter
is not required.
12.
Supercharger Oil Check -- Check oil every 30,000
miles (50 000 km) or 36 months. Add the proper
synthetic
oil. S.ee “Recommended Fluid and
Lubricants’’ in the Index.
* An Emission Control Service.
? 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’‘.
