Land Rover Discovery: Engine Cooling - Ingenium i4 2.0l Diesel Cooling System Partial Draining, Filling and Bleeding (G1879553) / General Procedures

DRAINING

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:

Make sure to support the vehicle with axle stands.

Raise and support the vehicle.

WARNINGS:

• 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.
• Be prepared to collect escaping fluid.
• 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.

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

Position a container to collect the fluid.

CAUTION:

Be prepared to collect escaping fluids.

• Attach a hose to the radiator drain tap. Open the tap.
• Allow the coolant to drain into a suitable container.

Tighten the radiator drain tap.

Remove the container.
