Cooling System Draining and Vacuum Filling
NOTE:
Removal steps in this procedure may contain installation details.
1 Disconnect the battery ground cable.
For additional information, refer to Specifications Battery and Charging System
For additional information, refer to Engine Cover - 5.0L Service and Repair
WARNING: Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.
2 Raise and support the vehicle.
For additional information, refer to Radiator Splash Shield Radiator Splash Shield
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.
CAUTION: 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
CAUTION: Be prepared to collect escaping coolant.
CAUTION: Be prepared to collect escaping coolant.
Position a container to collect the fluid.
Attach a hose to the radiator drain tap. Open the tap.
Torque to: 2 Nm

1 Lower the vehicle.
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.
NOTE:
Make sure the coolant supply valve is in the closed position on the vacuum filler gauge assembly.
NOTE:
The coolant vacuum fill tool needs an air pressure of 6 to 8 bar (87 to 116 psi) to operate correctly.
NOTE:
Small diameter or long airlines may restrict airflow to the coolant vacuum fill tool.
2 Connect a regulated compressed air supply to the venturi tube assembly.
3 Position the evacuated air hose into a container.
4 Open the air supply valve.
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.
5 Open the coolant supply valve for 2 seconds to prime the coolant supply hose.
6 Apply air pressure progressively until the arrow on the vacuum filler gauge reaches the green segment.
7 Disconnect the compressed air supply line.
NOTE:
Close the coolant supply valve when the coolant expansion tank MAX mark is reached or coolant movement has ceased.
8 Open the coolant supply valve and allow the coolant to be drawn into the system.
9 Remove the vacuum filler gauge and cooling system vacuum refill adaptor assembly.
10 Set the heater controls to maximum.
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
11 Start the engine and idle until hot air is emitted at the face registers.
12 Switch the heater off.
13 Raise the engine speed to 2000 RPM for eight minutes.
CAUTION: Switch off the engine and allow the coolant temperature to go cold.
14 Visually check the engine and cooling system for signs of coolant leakage.
WARNING: When releasing the cooling system pressure, cover the coolant expansion tank cap with a thick cloth.
CAUTION: 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
CAUTION: 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.
15 Check and top-up the coolant if required.
