Your vehicle may have 2 3800 Sqercharged engine.
Supercharging, rather
than turbocharging, emphasizes
smooth, refined power.
The supercharger is a device which is designed to pump
more ais 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, iwreased 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 tfarsttIe cruising, the excess air that the
supercharger is pumping is routed through a bypass.
AB1 sf these controk working together provide high
performance character and fuel efficiency in the
3800 V6 Supercharged engine.
The power steering pump and reservoir are mounted on
the rear (driver’s side) sf the engine biock. See
“Maintenance Schedule”
in the Index for when you
should check the fluid.

Did you know that used engine oil contains certain
ekmer,ts that may
be unhealthy for your skin and csdd
even cause cancer? Don’t let used oil stay on your skin
for very iong. Clean your skin and nails with soap and
water, or a good hznd cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about
the use and disposal
of oil products.)
Used oil can be a real t-heat to the environment. If you
change
your own oil, be sure to drain all free-flowing
oil
from the filter before disposal. Don’t ever dispose of
oil by putting it in the trash, pouring it on the ground,
into sewers, or into streams or bodies of water. Instead,
recycle it by taking it
to a place that coilects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer,
a service station or a local recycling
center for kelp.
