Land Rover Discovery: Engine Cooling - Ingenium i4 2.0l Diesel Cooling System Partial Draining and Vacuum Filling (G1809493) / General Procedures

SPECIAL TOOL(S)

DRAINING

WARNING:

Since injury such as scalding could be caused by escaping steam or coolant, do not remove the filler cap from the coolant expansion tank while the system is hot.

CAUTIONS:

• The engine cooling system must be maintained with the correct concentration and type of anti-freeze solution to prevent corrosion and frost damage. Failure to follow this instruction may result in damage to the engine.
• Engine coolant will damage the paint finished surfaces. If spilt, immediately remove the coolant and clean the area with water.

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.

WARNING:

Since injury such as scalding could be caused by escaping steam or coolant, do not remove the filler cap from the coolant expansion tank while the system is hot.

Refer to: Engine Undershield (501-02 Front End Body Panels, Removal and Installation).

Position a container to collect the fluid.

NOTES:

• Some components shown removed for clarity.
• Collect the coolant in a clean container and reuse.

• Attach a hose to the radiator drain tap.
• Open the radiator drain tap.
• Drain the coolant from the radiator.

Close the radiator drain tap and remove the hose.

FILLING

WARNING:

Since injury such as scalding could be caused by escaping steam or coolant, do not remove the filler cap from the coolant expansion tank while the system is hot.

CAUTIONS:

• The engine cooling system must be maintained with the correct concentration and type of anti-freeze solution to prevent corrosion and frost damage. Failure to follow this instruction may result in damage to the engine.
• Engine coolant will damage the paint finished surfaces. If spilt, immediately remove the coolant and clean the area with water.

Refer to: Engine Undershield (501-02 Front End Body Panels, Removal and Installation).

Prepare a sufficient amount of coolant to the specified concentration.

NOTES:

• Make sure the coolant supply valve is in the closed position on the special tool.
• The special 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.

Special Tool(s): HU-919, JLR-303-1634

2. Position the hose from the special tool into a container of clean coolant.
3. Connect a regulated compressed air supply to the special tool.
4. Move the special tool to the expansion tank.

NOTES:

• Make sure the coolant supply valve is in the closed position on the special tool.
• 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.

Open the air supply valve until -0.8 (-12 psi) Bar is shown on the gauge.

Special Tool(s): HU-919, JLR-303-1634

• Close the air supply valve.
• Allow 1 minute to check the vacuum is held.

NOTES:

• The coolant is to be reused.
• Close the coolant supply valve when the coolant expansion tank MAX mark is reached or coolant movement has stopped.

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

Special Tool(s): HU-919, JLR-303-1634

Remove the special tool.

Connect exhaust extraction hoses to the tail pipes.

Start and run the engine.

Install the coolant expansion tank cap.

Hold the engine speed at 2000 revolutions per minute (RPM) until warm air is expelled from the heater.

Switch the engine off and allow to cool.

Clean any spilt or excess coolant from the vehicle.

WARNING:

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

Check and top-up the coolant if required.
