coolant reservoir JAGUAR XJ 2004 X350 / 3.G Owners Manual

4-4 On the Road
Engine Temperature (E)
Drive at moderate road and engine
speeds until normal operating
temperature is reached. This is indicated
when the pointer is between the
blue (cold) segment and the red (hot)
segment.
The engine operating temperature will
vary with changes in weather and engine
load. The engine temperature may rise in
some circumstances, such as:
• Idling for long periods in slow moving traffic.
• Driving up a long hill in hot weather.
• Driving slowly or stopping after driving at high speed.
• Towing a trailer or caravan.!WARNING:
1. The radiator cooling fans may continue to run after the ignition
has been switched off but will
automatically switch off when the
engine has cooled sufficiently.
2. It is unsafe to run the engine in an overheated condition.
3. Do not remove the coolant reservoir filler cap while the
engine is hot. If it is essential, then
protect your hands against
escaping steam. SLOWLY turn the
cap anti-clockwise to allow the
steam pressure to escape
completely before removing the
cap. Should the pointer move into the red
segment (
H) of the coolant gauge, stop
the vehicle as soon as it is safely possible,
turn off the engine and open the hood to
allow the engine to cool.

Regular Checks
In the interests of safety and reliability,
it is advisable to carry out the following
checks at the recommended intervals,
and always before starting on a long
journey.
Daily
Check that there is sufficient fuel for the
journey intended, particularly at night
and before joining motorways.
Weekly
Tyres– Check the tyres, including the
spare, for condition and pressure.
Tyre pressures are explained on page 8 - 8
and shown on a label inside the fuel filler
flap.
Lights – Check that all exterior lights and
direction indicators function correctly
and that the lenses are clean.
Engine oil – With the vehicle standing
on level ground, check the oil level and
top up if necessary with oil of the correct
grade.
Engine coolant – With the engine cold,
check the level of the coolant in the
coolant reservoir header tank. Any loss of
fluid must be checked by a Jaguar
Retailer. Brake fluid
– Check the level of the fluid
in the brake fluid reservoir. Top up if
necessary with new, unused Jaguar
approved brake fluid.
The reservoir is initially nearly full,
but the level will drop as the brake pads
wear. If the level appears unusually low,
location of the fluid leakage must be
checked by a Jaguar Retailer.
Power steering fluid – With the engine
cold, check the level of the fluid in the
power steering fluid reservoir. Top up if
necessary with fluid of the correct
specification. Any loss of fluid should be
checked by a Jaguar Retailer.
Windscreen washer fluid – Top up
with windscreen washer fluid and clean
soft water. Check the operation of the
washers. It is recommended that you
use Jaguar Windscreen Washer Fluid to
keep the glass clean and also to prevent
the fluid from freezing during cold
weather.
Monthly
Wiper blades – Check the quality of the
wipe. If smearing or juddering is evident,
clean the windscreen and wiper blades.
Used Engine Oil
!WARNING:
Prolonged and repeated contact may
cause serious skin disorders,
including dermatitis and cancer.
Always use a hand cream to protect the
skin from oil contamination.
Avoid contact with the skin as far as
possible and wash thoroughly after any
contact. Keep oils out of reach of
children.
PROTECT THE ENVIRONMENT: It is
illegal to pollute drai ns, watercourses and
soil. Use authorised waste collection
facilities, including civic amenity sites and
garages providing fa cilities for the
disposal of used oi l, oil filters and
batteries. If in doubt, contact your Local
Authority for advice on disposal.

Maintenance 7 - 11
Check Coolant Level
Refer to page 7 - 5 for coolant header tank
location.
The coolant level MAX and MIN
indicators are located inside the reservoir
and are only visible when looking into the
filler neck with the cap removed. Check
the level only when the engine is cold.
The coolant level shou ld be between the
MAX and MIN indicators. If persistent
coolant loss is noticed, have a Jaguar
Retailer investigate the cause
immediately.
!WARNING:
Do not remove the coolant header
tank filler/pressure cap while the
engine is hot. If the cap must be
removed, protect the hands against
escaping steam and slowly turn the
cap anti-clockwise until the steam
starts to escape. Leave the cap in this
position until the pressure is
released, and then remove the cap.
Topping up
!WARNING:
Do not allow anti-freeze to make
contact with skin or eyes. If this
happens, rinse the affected area
immediately with plenty of water.
Caution: Anti-freeze will damage
paintwork. Avoid spillage.
Top up with a mixture of 50% water and
50% anti-freeze until the coolant is
between the MAX and MIN indicators
inside the header tank. Use anti-freeze to
specification WSS M97B44, coloured
orange, Extended Life Coolant.
Refit the filler cap and hand-tighten
securely until the ratchet operates. Engine anti-freeze
When used at the correct concentration,
anti-freeze not only protects the engine
from frost damage in winter, it also
provides all year round protection against
internal corrosion.
The cooling system should always be
topped up or refilled with the specified
anti-freeze at the correct concentration.
This 50/50% mixture gives frost
protection for temperatures down to
–40°F (–40°C).
Do not mix any other anti-freeze with
that specified; inferior quality anti-freeze
may be ineffective in maintaining
adequate frost and corrosion protection
to the cooling system.
The coolant solution
may remain in the
cooling system for five years or
156,000 miles (250,000 km) after which
the system should be drained, flushed
and refilled.
Engine block heater
For further information consult your
Jaguar Retailer.
Caution: The fitting of an engine
block heater does not eliminate the
need for anti-freeze under freezing
conditions.
