ring and carbon seal contact surface of shaft seal seat for damage.
Make sure that "O" ring contact surface on front cover is not damaged.
Make sure refrigerant oil is applied to oil seal in shaft seal seat.
Installation
1) To install, reverse removal procedure. Ensure shaft seal
contact surface is free of dirt. Lubricate with refrigerant oil. Cap
end of compressor shaft.
2) Using Guard (KV994C1143), insert shaft seal. Be sure shaft
seal case is aligned with shaft. Apply force to turn seal to left and
right. Ensure shaft seal seats properly in shaft cut-out.
3) Fit "O" ring to outside groove of shaft seal seat. Ensure
"O" ring seats properly. Apply refrigerant oil on contact surfaces and
around shaft seal seat. Lightly coat surface of shaft with refrigerant
oil.
4) Install key on compressor shaft. Using snap ring pliers,
compress retainer ring and fit retainer ring into front cover. Seat
retainer ring firmly in groove. Thoroughly wipe grease or oil from
shaft surface.
5) Connect Installer (KV99412329) to shaft of compressor, and

COMPUTER RELEARN PROCEDURES

ARTICLE BEGINNING
GENERAL INFORMATION
Computer Relearn Procedures
All Models
* PLEASE READ THIS FIRST *
The following general procedures are to be used if
driveability problems are encountered after power loss or battery has
been disconnected. These procedures may provide an aid in eliminating
these problems.
To reduce the possibility of complaints, after any service
which requires battery power to be disconnected, vehicle should be
road tested.
COMPUTER RELEARN PROCEDURES
Vehicles equipped with engine or transmission computers may
require a relearn procedure after vehicle battery is disconnected.
Many vehicle computers memorize and store vehicle operation patterns
for optimum driveability and performance. When vehicle battery is
disconnected, this memory is lost. The computer will use default data
until new data from each key start is stored. As computer memorizes
vehicle operation for each new key start, driveability is restored.
Vehicle computers may memorize vehicles operation patterns for 40 of
more key starts.
Customers often complain of driveability problems during
relearn stage because vehicle acts differently then before being
serviced. Depending on type and make of vehicle and how it is
equipped, the following complaints (driveability problems) may exist:
* Harsh Or Poor Shift Quality
* Rough Or Unstable Idle
* Hesitation Or Stumble
* Rich Or Lean Running
* Poor Fuel Mileage
These symptoms and complaints should disappear after a number
of drive cycles have been memorized. To reduce the possibility of
complaints, after any service which requires battery power to be
disconnected, vehicle should be road tested. If a specific relearn
procedure is not available, the following procedure may be used:
Automatic Transmission
* Set parking brake, start engine in "P" or "N" position.
Warm-up vehicle to normal operating temperature or until
cooling fan cycles.
* Allow vehicle to idle for one minute in "N" position. Select

start at any time even when the ignition key is in the OFF
position. DO NOT loosen or remove radiator cap when cooling
system is hot.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See COMPUTER
RELEARN PROCEDURES article in GENERAL INFORMATION section.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.
HALOGEN BULBS
Halogen bulbs contain pressurized gas which may explode if
overheated. DO NOT touch glass portion of bulb with bare hands. Eye
protection should be worn when handling or working around halogen
bulbs.
SUPPLEMENTAL RESTRAINT SYSTEM (AIR BAG)
NOTE: See the AIR BAGS article in the ACCESSORIES/SAFETY EQUIPMENT
Section.
Modifications or improper maintenance, including incorrect
removal and installation of the Supplemental Restraint System (SRS),
can adversely affect system performance. DO NOT cover, obstruct or
change the steering wheel horn pad in any way, as such action could
cause improper function of the system. Use only plain water when
cleaning the horn pad. Solvents or cleaners could adversely affect the
air bag cover and cause improper deployment of the system.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all warnings and service precautions. See
appropriate AIR BAGS article in ACCESSORIES/SAFETY EQUIPMENT.
CAUTION: Disconnect negative battery cable before servicing any air
bag system, steering column or passenger side dash
component. After any repair, turn ignition key to the ON

These vehicles may require a relearn procedure. See COMPUTER
RELEARN PROCEDURES article in GENERAL INFORMATION section.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BRAKE PAD REPLACEMENT
WARNING: Use caution when checking and/or changing brake pads, some
pads may contain asbestos which can irritate eyes and may
cause other health hazards. A water based solution should be
used to clean brake dust from wheel and brake components.
DO NOT use compressed air to blow off brake dust.
BRAKE SYSTEM
CAUTION: If brake warning light comes on while driving it indicates
a low fluid level or failure in one of the braking
circuits. If the brake pedal can be depressed further than
normal it is an indication that one of the brake circuits
is not functioning. Stop vehicle and check brake reservoir
fluid level. If level is below MIN mark, DO NOT drive
vehicle. Have it towed to a repair shop. If level is
between the MIN and MAX marks, proceed cautiously to a
repair shop.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.
BRAKE PEDAL PRESSURE WITH ENGINE NOT RUNNING
CAUTION: Brake pedal requires extreme pressure to stop the vehicle
when the engine is not running.
CATALYTIC CONVERTER
Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible damage to
converter and vehicle.
Any modification to the exhaust system on turbo models, which
reduces exhaust backpressure, will lead to lean fuel mixtures and
excessive spark advance. This could cause serious engine damage.
