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.
