Cooling System Draining and Vacuum Filling
Trustmark Authoring Standards (TAS) Repair Procedures
NOTE: TAS style procedures can be identified by steps that have no accompanying step text and the magenta color of the electrical connectors and fasteners such as nuts, bolts, clamps or clips.
A TAS removal and installation procedure uses a sequence of color illustrations to indicate the order to be followed when removing/disassembling or installing/assembling a component.
Specification data
Specification procedures will only contain technical data that is not already part of a repair procedure.
Sequence of tasks
If components must be removed or installed in a specific sequence, the sequence will be identified numerically in a graphic and the corresponding text will be numbered accordingly.
Special Tools, Equipment, Materials and Torque Figures
Special tools will be shown with the tool numbers in the illustration. The special tool numbers, general equipment, materials and torque figures used for the procedure step will be shown in the text column.
TAS Graphics
Colors used in the graphic are as follows:
Blue - Component to be removed/installed or disassembled/assembled.
Green and Brown - Additional components that need to be removed/installed or disassembled/assembled prior to the target component.
Yellow - Component that is touched or affected in a way but remains in the vehicle. It may be detached, attached, moved, modified, checked, adjusted etc.
Magenta - Electrical connectors and fasteners such as nuts, bolts, clamps and clips.
Pale Blue - Special tool(s) and general equipment.
One illustration may have multiple steps assigned to it.
Numbered pointers are used to indicate the number of electrical connectors and fasteners such as nuts, bolts, clamps and clips.
Items in the illustration can be transparent or use cutouts to show hidden details.

General Procedures
Draining
WARNING: 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.
All vehicles
1. WARNING: Make sure to support the vehicle with axle stands.
Raise and support the vehicle.
2.
3. Refer to: Engine Undershield.
Vehicles without supercharger
4. Refer to: Air Cleaner Outlet Pipe T-Connector.
Vehicles without supercharger
5. Refer to: Air Cleaner Outlet Pipe T-Connector.
All vehicles
6. WARNING: When releasing the cooling system pressure, cover the coolant expansion tank cap with a thick cloth.
7. CAUTION: Be prepared to collect escaping coolant.
8. CAUTION: Be prepared to collect escaping coolant.
NOTE: Step 9-12 and 15-16 only needs to be carried out when auxiliary climate control system has been fitted to the vehicle.
9. Remove the front RH wheel arch liner.
Refer to: Fender Splash Shield.
10. CAUTION: Be prepared to collect escaping coolant.
11. Remove the rear LH wheel arch liner.
Refer to: Rear Fender Splash Shield.
12. CAUTION: Be prepared to collect escaping coolant.
13. Torque: 5 Nm

17. Carry out the procedure up to step 1 in the filling section three times, filling the cooling system with clean water at the first two drains. At the third refill, use a suitable measuring tool to make sure that the cooling system maintains a 50% mix.
Filling
1. 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.
2. NOTE:
- 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.
3. Position the evacuated air hose into a container.
4. Open the air supply valve.
5. 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.
6. Apply air pressure progressively until the arrow on the vacuum filler gauge reaches the green segment.
7. Disconnect the compressed air supply line.
8. 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.
9. Remove the vacuum filler gauge and cooling system vacuum refill adaptor assembly.
10. Continue to fill the coolant expansion tank to the rim until the coolant level stops dropping.
11.
12. Start and run the engine.
13. Set the heater controls to maximum.
14. Increase the engine speed from idle to 3500 RPM until hot air is emitted from the front and rear face vents.
15. Run the engine until the thermostat opens and hot air is emitted from the front and rear face vents.
16. Switch the engine off and allow to cool.
17. Visually check the engine and cooling system for signs of coolant leakage.
18.
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.
