and Vacuum Filling
General Procedures

Draining

1. Refer to: Radiator Splash Shield (501-02 Front End Body Panels, Removal and Installation).


2. WARNING: Release the cooling system pressure by slowly
turning the coolant expansion tank cap a quarter of a turn.
Cover the expansion tank cap with a thick cloth to prevent
the possibility of scalding. Failure to follow this instruction
may result in personal injury.
CAUTIONS:


Since injury such as scalding could be caused by
escaping steam or coolant, make sure the vehicle cooling
system is cool prior to carrying out this procedure


Be prepared to collect escaping coolant.



3. WARNING: Do not work on or under a vehicle supported only by a jack.
Always support the vehicle on safety stands.
Raise and support the vehicle.


4. CAUTION: Be prepared to collect escaping coolant.

3. CAUTION: Anti-freeze concentration must be maintained at 50%.

Install the cooling system vacuum refill adaptor to the expansion
tank.
Install the vacuum filler gauge to the cooling system vacuum
refill adaptor.
Install the venturi tube assembly to the vacuum filler gauge.

4. NOTES:


Make sure the coolant supply valve is in the closed position on the
vacuum filler gauge assembly.


The coolant vacuum fill tool needs an air pressure of 6 to 8 bar (87
to 116 psi) to operate correctly.


Small diameter or long airlines may restrict airflow to the coolant
vacuum fill tool.

Connect a regulated compressed air supply to the venturi tube
assembly.

5. Position the evacuated air hose into a container.

6. Open the air supply valve.


7. NOTE: Make sure the coolant supply hose is positioned into a container
of fifty percent mixture of Jaguar Premium Cooling System Fluid or
equivalent, meeting Jaguar specification WSS M97B44-D and fifty
percent water. Make sure no air can enter the coolant supply hose.

Open the coolant supply valve for 2 seconds to prime the coolant supply
hose.

8. Apply air pressure progressively until the arrow on the vacuum filler
gauge reaches the green segment.

9. Disconnect the compressed air supply line.


10. NOTE: Close the coolant supply valve when the coolant expansion
tank MAX mark is reached or coolant movement has ceased.

Open the coolant supply valve and allow the coolant to be drawn into
the system.

11. Remove the vacuum filler gauge and cooling system vacuum refill
adaptor assembly.

12.














13.
Set the heater controls to maximum.


14. CAUTION: Observe the engine temperature gauge. If the engine
starts to over-heat switch off immediately and allow to cool. Failure to
follow this instruction may cause damage to the vehicle
Start the engine and idle until hot air is emited at the face registers.

15. Switch the heater off.

16. Raise the engine speed to 2000 RPM for eight minutes.


17. CAUTION: Switch off the engine and allow the coolant temperature
to go cold.
Switch the engine off.

18. Visually check the engine and cooling system for signs of coolant
leakage.


19. WARNING: When releasing the cooling system pressure, cover the
coolant expansion tank cap with a thick cloth.
CAUTIONS:


Since injury such as scalding could be caused by escaping steam or
coolant, make sure the vehicle cooling system is cool prior to carrying
out this procedure


Make sure the coolant level remains above the "COLD FILL RANGE"
lower level mark.


NOTE: When the cooling system is warm, the coolant will be
approximately 10mm above the upper level mark on the expansion tank
with the cap removed.
Check and top-up the coolant if required.

Filling

1. Refer to: Radiator Splash Shield (501-02 Front End Body Panels, Removal and Installation).

2. Lower the vehicle.

3.
4. CAUTION: Anti-freeze concentration must be maintained at 50%.

Fill the cooling system, keeping coolant to the upper level mark of the
expansion tank until a steady stream of coolant is seen running from the
coolant hose bleed point.

5.
Continue to fill the coolant until the maximum level
is reached.


















6. Set the heater controls to maximum.

7. Start engine and increase speed to 2000 rpm for 2 minutes.

8.
Continue to top-up with coolant with engine idling until hot air is
emitted from face vents.
When hot air is emitted from the vents, switch the heater off. Go
to Step 10.

9. If no hot air is emitted, turn the engine off for 10 seconds and the start
the engine and return to Step 7.


10. CAUTION: Correct installation of the Coolant
expansion tank cap can be obtained by tightening the cap
until an audible click is heard.

Continue to fill the coolant until the maximum level is
reached.









11. Switch the heater off.

12. Raise the engine speed to 2000 rpm for eight minutes.

13. Switch the engine off and allow to cool.

14. Visually check the engine and cooling system for signs of coolant
leakage.
