suds.

with a clean cloth.
USING SOLVENT-TYPE CLEANER ON
FMRIC
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean
off better with just water and mild soap.
If you need to use it, then:
0 Gently scrape excess soil from the trim material with a clean, dull
knife
or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start
at the outside of the
stain, “feathering” toward the center. Keep changing to
a clean
section
of the cloth.
0 When you clean a stain from fabric, immediately dry the area with an
air hose, hair dryer, or heat lamp
to help prevent a cleaning ring. (See
the previous
NOTICE.)

WINDSHIELD
AND WIPER BLADES
If the windshield is not clear after using the windshield washer, or if the
wiper blade chatters when running, wax or other material may be on the
blade
or windshield.
Clean the outside
of the windshield with GM Windshield Cleaner,
Bon-Ami Powder@
(GM Part No. 105001 I). The windshield is clean if
beads do not form when you rinse it with water.
Clean the blade by wiping vigorously with
a cloth soaked in full strength
windshield washer solvent.
Then rinse the blade with water.
Wiper blades should be checked
on a regular basis and replaced when
worn.
CLEANING THE OUTSIDE OF YOUR
CADILLAC
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Hhicle
The best way to preserve your vehicle’s finish is to keep it clean by
washing it often with lukewarm or cold water.
Don’t wash your vehicle
in the direct rays of the sun. Don’t use strong
soaps or chemical detergents. Use liquid hand, dish or car washing
(non-detergent) soaps. Don’t use cleaning agents that contain acid or
abrasives.
All cleaning agents should be flushed promptly and not allowed
to dry
on the surface, or they could stain. Dry the finish with a soft, clean
chamois or a
100% cotton towel to avoid surface scratches and water
spotting.
High pressure vehicle washes may cause water to enter your vehicle.

Downloaded from www.Manualslib.com manuals search engine The Northstar engine is designed to require less maintenance than many
other
DOHC V-8 engines. Engine systems are designed to remind the
driver when service is required. An oil life index indicator monitors
ongoing operating conditions and reminds the driver when
an oil change
is needed. A low coolant warning message keeps track
of the level of this
vital fluid. Direct acting hydraulic tappets provide maintenance free zero
lash operation
of the 32 valves from idle to the 6500 rpm redline. The
camshafts are driven by a
two stage roller chain assembly which is
designed to provide quiet maintenance free operation. Platinum tipped
spark plugs increase the replacement interval to
100,000 miles.
The four valve per cylinder design provides more
efficient engine
breathing which results
in higher power than comparable two valve
engines. The central location
of each spark plug ensures a fast and
complete burning
of the fuel/air mixture. The induction system uses
smooth thermoplastic tubes to channel air into the cylinders. The
smoothness
of the tubes is equivalent to the elaborate port polishing
methods used for race car engines. Careful design using the shape and
length
of the tubes boosts horsepower by using sonic pressure waves
created by the motion
of the inlet valves to increase the amount of air
entering each cylinder.
The Northstar engine
is also designed to be very durable. The aluminum
block has cast-in-place iron cylinder liners for greater wear resistance.
High strength forged steel connecting rods support the free floating \
piston pins
in bronze bushings for superior high speed performance. The
fillits
of the nodular iron crankshaft undergo a high pressure compression
rolling operation to improve their resistance to fatigue.
Quiet operation
is enhanced by the use of special materials and designs.
The front cover of the engine is stamped from laminated steel which
damps
out noise. Special cam cover gasket seals isolate valve train
operation. The
fuel injectors are placed inside the induction system
housing
to eliminate the clicking noise which is common to other fuel
injected engines.
The Northstar engine is designed
to provide years of efficient, reliable,
satisfying operation. We think
it is also just plain fun to drive.

Downloaded from www.Manualslib.com manuals search engine This transaxle is the first of a new generation of “SMART” transmissions.
The computer which controls the electronic shift solenoids adapts to
changing environments while you drive. This provides consistent high
quality shifts under all conditions. Communication between the engine
and transaxle through this computer controls engine output durin\
g
activation
of torque management or traction control. Smooth shifting is
ensured by design. Hydraulic accumulators control shift pressures and all
shifts are made to free wheeling elements.
The 4T80E uses a dry sump lubrication system with a scavenger pump.
This unique feature enables the transaxle to maintain adequate
pressurized oil supply during
all maneuvers.
Spirited performance with
very efficient cruising operation are provided
by the combination
of 4 speed overdrive gearing, a torque converter
clutch, and a
3.71:l or 3.11:l final drive ratio.
4T60-E Transaxle (4.9 L Eldoradu)
340

Downloaded from www.Manualslib.com manuals search engine The Hydra-matic 4T60-E 4-speed overdrive, electronic transaxle consists
primarily
of a five element torque converter: two planetary gear sets,
various clutches, final drive assembly, differential 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 additional torque when required. When applied,
the pressure plate provides a mechanical direct drive coupling
of the
engine to the transaxle.
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.

The power rack and pinion steering system,has a rotary spool valve which
directs hydraulic fluid coming from the power steering pump
to one side
or the other side
of the rack piston. The integral rack piston is attached to
the rack. The rack piston converts hydraulic pressure
to a linear force
which moves the rack left or right. The force
is then transmitted through
the inner and outer tie rods to the steering knuckles, which turn the
wheels
If hydraulic assist is not available, manual control is maintained. However
under these conditions more steering effort
is required.
