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.
