Downloaded from www.Manualslib.com manuals search engine - Headlights
The headlight wiring is protected by a circuit breaker in the light switch.
An electrical overload will cause the lights to go on and off, or in some
cases to remain off.
If this happens, have your headlight wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker and a fuse.
If the motor overheats due to heavy snow, etc., the wiper will stop until
the motor cools. If the overload is caused by some electrical problem and
not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other
opens and closes, protecting the circuit until the problem is fixed or goes
away.

4.9 Liter Engine
The 4.9 Liter transverse engine is an overhead valve 90 degree V-8
design. The cylinder bore diameter and the piston stroke provide a piston
displacement of
300 cubic inches (4.9Liter).
This engine utilizes an aluminum crankcase with a separate aluminum
lifter carrier and removable cast iron cylinder liners. The cylinder heads
ar,e made
of cast iron and feature intergral valve seats and guides. The
cast nodular iron crankshaft is supported at five main bearing journals by
cast iron main bearing caps and shell type steel-backed aluminum inserts.
The center main bearing
is the thrust bearing.

Downloaded from www.Manualslib.com manuals search engine The cast aluminum pistons use two compression rings and one oil control
ring. The pistons are tin plated to provide a non-scuffing surface when
the engine is new.
c_ A steel camshaft is supported by five steel backed babbit bearings. It is
driven by the crankshaft through a chain at
the front of the engine. The
give gear is keyed to the crankshaft and the driven sprocket is bolted to
the camshaft. Both the crankshaft gear and camshaft sprocket have
locating marks to provide the correct valve timing and timing chain
installation.
The valve lifters are roller hydraulic type and are positioned
in the aluminum lifter carrier.

4T60E Transaxle
The Hydra-Matic 4T60E 4-speed overdrive, electronic transaxle consists
primarily of a five element torque converter,
two planetary gear sets,
-- various clutches, final drive assembly, and a control valve body.

The torque converter houses a pump, turbine, pressure plate which is
splined to the turbine, and a stator assembly, serving as a fluid coupling, it
smoothly transmits power from the engine to the transaxle. It also
hydraulically provides a additional torque when required. When applied,
the pressure plate provides a mechanical torque when required. When
applied, the pressure plate provides a mechanical direct drive coupling of
the engine to the transaxle.

n
The two planetary gear sets provide the four forward gear ratios and
reverse. Changing of the gear ratios is fully automatic and is
accomplished through the use of various electronic and mechanical
requirements. Four multiple disc clutches, two roller clutches, a sprag
clutch, and three bands provide the friction elements required to obtain
the various ratios with the planetary gear sets.
A hydraulic system (the control valve body) pressurized by a vein type
pump provides the working pressure needed to operate the friction
elements and automatic controls.
Front Suspension
Your fully independent front suspension is a combination strut and spring
design. The frame is isolated from the body with six rubber mounts.
r

Downloaded from www.Manualslib.com manuals search engine Rubber bushings are used at the lower control arm pivots. The upper end
of the strut is isolated by a rubber mount which contains a bearing to
allow for wheel turning. The Speed Sensing Suspension automatically
controls the damping rate
of the struts.
The lower end
of the steering knuckle pivots on a ball joint riveted to the
control arm. The ball joint
is connected ,to the steering knuckle with a
castellated nut and cotter pin.
ShortlLong Arm Suspension (SLA)
Your vehicle uses an independent short/long arm rear suspension. All the
rear suspension components are mounted
on a suspension support which
is attached to the body at four points and is
fully isolated with bushings
and insulators to minimize road noise. Each rear wheel is connected to
the suspension support through the suspension knuckle using
an upper
and lower control arm and
toe link. --
