Land Rover Discovery (2009–2016) Service Manual / Powertrain / Engine / 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.
