1997 JAGUAR XJ6 airbag off

4Remove the water pump mounting bolts
(see illustration).
Note 1:The water pump is sold as a complete
assembly, including the rear housing with the
hose connections. Unless the rear housing is
corroded or cracked, many Jaguar mechanics
only refit the pump assembly itself, using the
original rear housing with all its hoses intact.
However, if the engine has a great deal of
years or mileage on it, it would be a good idea
to renew those hoses as well, in which case
the new rear housing can be installed.
Note 2:There are three different lengths of
water pump bolts. The longer bolts retain the
pump and rear housing to the engine(see
illustration 7.3).
5If the pump doesn’t come loose right away,
tap it with a soft-faced hammer to break the
gasket seal. Be careful not to hit the radiator
fins with the pump during removal.
6Thoroughly clean all sealing surfaces,
removing all traces of gasket or sealant from
the back of the pump and the face of the
housing.
7Apply a bead of RTV sealant to the sealing
surface on the back of the pump. Refit the
pump and bolts, tightening the bolts to the
torque listed in this Chapter’s Specifications.
8Refit the remaining parts in the reverse
order of removal. Note:If the pump has been
renewed after many miles of usage, it’s a good
idea to also renew the hoses connected to the
water pump housing(see illustrations). Refer
to Chapter 2A for intake manifold removal to
access the coolant pipes and hoses. If you
have noticed water leaks or stains on the left
side of the engine, the leaks may be coming
from these pipes and hoses.
9Refill the cooling system (see Chapter 1),
run the engine and check for leaks and proper
operation.

Warning: Do not start this
procedure until the engine is
completely cool.
Check
1If the coolant temperature gauge is
inoperative, check the fuses first (Chapter 12).
2If the temperature gauge indicates
excessive temperature after running awhile,
see the Fault finding section at the rear of the
manual.
3If the temperature gauge indicates Hot as
soon as the engine is started cold, disconnect
the wire at the coolant temperature sender
(see illustration). If the gauge reading drops,
renew the sender unit. If the reading remains
high, the wire to the gauge may be shorted to
ground, or the gauge is faulty.
4If the coolant temperature gauge fails to
show any indication after the engine has been
warmed up, (approx. 10 minutes) and the
fuses checked out OK, shut off the engine.
Disconnect the wire at the sender unit and,
using a jumper wire, connect the wire to a
clean ground on the engine. Briefly turn on the
ignition without starting the engine. If the
gauge now indicates Hot, renew the sender
unit.
5If the gauge fails to respond, the circuit may
be open or the gauge may be faulty - see
Chapter 12 for additional information.
Renewal
6Drain the coolant (see Chapter 1).
7Disconnect the electrical connector from
the sender unit.8Using a deep socket or a spanner, remove
the sender unit.
9Refit the new unit and tighten it securely.
Do not use thread sealant as it may
electrically insulate the sender unit.
10Reconnect the wiring connector, refill the
cooling system and check for coolant leakage
and proper gauge function.

Warning: Later models are
equipped with airbags. To
prevent accidental deployment
of the airbag, which could cause
personal injury or damage to the airbag
system, DO NOT work in the vicinity of the
steering wheel or instrument panel. Jaguar
recommends that, on airbag-equipped
models, the following procedure should be
left to a dealer service department or other
repair workshop because of the special
tools and techniques required to disable
the airbag system.
1Disconnect the battery negative cable.
Caution: If the stereo in your vehicle is
equipped with an anti-theft system, make
sure you have the correct activation code
before disconnecting the battery.
2There are two blower motors, one under the
left side of the dash and one behind the glove
compartment (see illustration). If the blower
doesn’t work, check the fuse and all
connections in the circuit for looseness and
corrosion. Make sure the battery is fully
charged. To access the right blower, remove
the glove compartment liner, the glove
compartment door and the right lower dash
panel (see Chapter 11).
Warning: When working around
the area behind the glove box,
watch out for a strip of sheet
metal bracing that has a very
sharp edge (see illustration). Apply some
heavy duct tape to the edge of the brace
before beginning work in this area, or you
could injure your hands.

the plastic plate holding the motor and fan
(see illustration). The fan doesn’t come off
the motor, but loosen the clamp-bolt on the
motor’s mount bracket and slide the motor
and fan out for renewal (see illustration).
Note:Some 1988 models had problems with
cracking of the fan blades and noise from the
blowers. These blowers and fans have been
superseded with improved parts, available
from your Jaguar dealer.
12When either blower housing is separated,
you’ll find two relays mounted inside (see
illustration). These are the blower isolation
relay and blower relay. Before refitting the
blower housing in the car, refer to Chapter 12
for testing of these relays.

Do not loosen any hose fittings
or remove any components until
the system has been discharged. Air
conditioning refrigerant should be properly
discharged into an EPA-approved
recovery/recycling unit by a dealer service
department or an automotive airconditioning repair facility. Always wear
eye protection when disconnecting air
conditioning system fittings.
Warning 2: Later model vehicles
are equipped with airbags. To
prevent the accidental
deployment of the airbag, which
could cause personal injury or damage to
the airbag system, DO NOT work in the
vicinity of the steering wheel or instrument
panel. The manufacturer recommends
that, on airbag-equipped models, the
following procedure should be left to a
dealer service department or other repair
workshop because of the special tools and
techniques required to disable the airbag
system.
1Refer to Chapter 11 for removal of the glove
compartment, under-dash panels and
console. Note:The removal of the
heater/evaporator housing is difficult and
time-consuming, much more so than the
removal of the heater core (see Section 11).
For some home mechanics, the job is better
left to a Jaguar dealership or other qualified
repair workshop.
2Disconnect the air conditioning lines from
the backside of the expansion valve (at the
bulkhead, just to the right of the engine), usingtwo spanners (see illustration). Cap the open
fittings and expansion valve after dismantling

in your particular vehicle should always be
checked for up-to-date information.
2 Electronic control system
and ECU
General description
Note: These models are susceptible to ECU
damage if water is allowed to build up in the
front cowl drain and overspill into the dash
area near the computer. Inspect and clear the
front cowl drain as a regular maintenance item
to keep the water draining properly. Remove
the duckbill-type rubber hose and inspect it
for clogging, collapsing or deterioration.
1The Lucas LH Engine Management system
controls the fuel injection system by means of
a microcomputer known as the Electronic
Control unit (ECU).
2The ECU receives signals from various
sensors which monitor changing engine
operating conditions such as intake air mass,
intake air temperature, coolant temperature,
engine rpm, acceleration/deceleration,
exhaust oxygen content, etc. These signals
are utilised by the ECU to determine the
correct injection duration.
3The system is analogous to the central
nervous system in the human body: The
sensors (nerve endings) constantly relay
signals to the ECU (brain), which processes
the data and, if necessary, sends out a
command to change the operating
parameters of the engine (body).
4Here’s a specific example of how one
portion of this system operates: An oxygen
sensor, located in the exhaust manifold,
constantly monitors the oxygen content of the
exhaust gas. If the percentage of oxygen in
the exhaust gas is incorrect, an electrical
signal is sent to the ECU. The ECU takes this
information, processes it and then sends a
command to the fuel injection system telling it
to change the air/fuel mixture. This happens in
a fraction of a second and it goes on
continuously when the engine is running. The
end result is an air/fuel mixture ratio which is
constantly maintained at a predetermined
ratio, regardless of driving conditions.
5In the event of a sensor malfunction, a
backup circuit will take over to provide
driveability until the problem is identified and
fixed.
Precautions
6Follow these steps:
a) Always disconnect the power by either
turning off the ignition switch or
disconnecting the battery terminals before
removing electrical connectors.
Warning: Later models are
equipped with airbags. To
prevent accidental deployment ofthe airbag, which could cause personal
injury, DO NOT work in the vicinity of the
steering column or instrument panel. The
manufacturer recommends that, on airbag
equipped models, the following procedure
should be left to a dealer service
department or other repair workshop
because of the special tools and techniques
required to disable the airbag system.
Caution: If the stereo in your vehicle is
equipped with an anti-theft system, make
sure you have the correct activation code
before disconnecting the battery.
b) When refitting a battery, be particularly
careful to avoid reversing the positive and
negative battery cables. Also, make sure
the ignition key is in the Off position when
connecting or disconnecting the battery.
c) Do not subject EFI components,
emissions-related components or the
ECU to severe impact during removal or
refitting.
d) Do not be careless during fault diagnosis.
Even slight terminal contact can invalidate
a testing procedure and damage one of
the numerous transistor circuits.
e) Never attempt to work on the ECU or
open the ECU cover. The ECU is
protected by a government-mandated
extended warranty that will be nullified if
you tamper with or damage the ECU.
f) If you are inspecting electronic control
system components during rainy weather,
make sure that water does not enter any
part. When washing the engine
compartment, do not spray these parts or
their electrical connectors with water.
g) These models are susceptible to ECU
damage if water is allowed to build up in
the front cowl drain and overspill into the
dash area. Inspect and clear the front
cowl drain system as a regular
maintenance item to keep the water
draining properly. Remove the duckbill
type rubber hose and inspect it for
clogging, collapsing or deterioration.

7Disconnect the negative cable from the
battery (see Chapter 5).
Warning: Later models are
equipped with airbags. To
prevent the accidental deploy-
ment of the airbag, which could
cause personal injury, DO NOT work in the
vicinity of the steering column or
instrument panel. The manufacturer
recommends that, on airbag equipped
models, the following procedure should be
left to a dealer service department or other
repair workshop because of the special
tools and techniques required to disable
the airbag system.
Caution: If the stereo in your vehicle is
equipped with an anti-theft system, make

3 On Board Diagnosis (OBD)
system- description and fault
code access
2
Note: 1990 and 1991 models may set
Code 69 erroneously. If the battery voltage
drops sufficiently and the ignition key is
switched quickly from OFF to START, battery
voltage will be lowered and during cranking
causing a delayed park/neutral signal from the
decoder module to the ECU. Check all the
battery connections and the condition of the
battery and then check the rotary switch
adjustment in Chapter 7 to remedy this code.
General information
1The ECU contains a built-in self-diagnosis
system which detects and identifies
malfunctions occurring in the network. When
the ECU detects a problem, three things
happen: the CHECK ENGINE light comes on,
the fault is identified and a diagnostic code is
recorded and stored. The ECU stores the
failure code assigned to the specific problem
area until the diagnosis system is cancelled.
Note: 1988 and 1989 models are not
equipped with long term memory. It is
possible to access the codes but the operator
must remember to NOT turn the ignition key to
the OFF position after the CHECK ENGINE
light has been noticed. The codes will be lost
and it will be necessary to start the engine and
operate the vehicle through a complete drive
cycle to allow the fault code(s) to be set once
again. Instead of turning the ignition key to the
OFF position, simply stop at position II (key
ON but engine not running) to retain the fault
codes.
