Supercharger Cooling System Draining, Filling and Bleeding - General Procedures

    WARNING: Never remove the coolant expansion tank pressure cap under any circumstances while the engine is operating. Failure to follow this instruction may result in personal injury.
    WARNING: To avoid hot coolant or steam blowing out of the cooling system, use extreme care when removing the coolant expansion tank pressure cap. Wait until the engine has cooled down, then insulate the coolant pressure cap with a suitable cloth and slowly loosen the coolant expansion tank pressure cap until the cooling system pressure is released. Do not remove the coolant expansion tank pressure cap. Step back while the pressure is released from the system. When all of the pressure has been released slowly remove the coolant expansion tank pressure cap (still with the suitable cloth in position) from the coolant expansion tank. Failure to follow this instruction may result in personal injury.
    WARNING: Remove fuse 14 from the engine management fuse box prior to performing any under hood service in the area of the cooling fan when the engine is hot, since the cooling fan motor could operate if the engine has been switched OFF. Failure to follow this instruction may result in personal injury.
    CAUTION: The engine cooling system must be maintained with the correct concentration and type of anti-freeze solution to prevent corrosion and frost damage.
    CAUTION: Never remove the coolant pressure cap under any circumstances while the engine is operating. Failure to follow this instruction may result in damage to the engine.
  1. Release the cooling system pressure.
    • Remove the expansion tank cap.
  2. Raise and support the vehicle. Refer to Jacking and Lifting article.

    4. CAUTION: Do not over tighten the radiator drain plug. Failure to follow this instruction may cause damage to the vehicle.
  4. Install the radiator drain plug when all coolant has drained.
    • Remove the container.
    • Clean off any spillages.
    5. CAUTION: The supercharger cooling system must be maintained with the correct concentration and type of coolant solution to prevent corrosion and frost damage.
    NOTE: Jaguar recommends filling the cooling system with softened water.
  5. Fill the cooling system up to the MAX mark on the coolant expansion tank using a fifty percent mixture of Jaguar Premium Cooling System Fluid or equivalent, meeting Jaguar specification WSS M97B44-D and fifty percent water.
  6. Install the expansion tank pressure cap.

  7. Remove the supercharger coolant fill plug.
    • Remove and discard the sealing washer.
    8. NOTE: Place a suitable cloth around supercharger fill port.
    NOTE: Jaguar recommends filling the cooling system with softened water.
  8. Top up the coolant through the supercharger fill port.
    9. CAUTION: Coolant may spill from supercharger fill port when ignition switched on.
  9. Switch ignition on.
    10. CAUTION: Do not allow the supercharger water pump to run dry for more than one minute. Failure to follow this instruction may result in damage to the vehicle.
  10. Allow the supercharger water pump to run and top up the coolant through supercharger fill port.
  11. Switch the ignition off.

  12. Install the supercharger coolant fill plug.
    • Install a new sealing washer.
    • Tighten to 45 Nm.
    • Clean off any spillages.
    13. CAUTION: Install fuse 14 to the engine management fuse box. Failure to follow this instruction may result in damage to the vehicle.
    CAUTION: Do not RUN the engine with the coolant expansion tank pressure cap removed. Failure to follow this instruction may cause damage to the vehicle
  13. START and RUN the engine.
  14. SET the heating system to MAX heat, the blower motor to MAX speed and the air distribution to instrument panel registers.
    15. 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.
  15. Allow the engine to RUN until hot air is emitted from the instrument panel registers, while observing the engine temperature gauge.
  16. Switch off the engine.
  17. Allow the engine to cool.
  18. Release the cooling system pressure.
    • Remove the coolant expansion tank pressure cap.
    19. CAUTION: The cooling system must be maintained with the correct concentration and type of coolant solution to prevent corrosion and frost damage.
    NOTE: Jaguar recommends filling the cooling system with softened water.
  19. Fill the cooling system up to the MAX mark on the coolant expansion tank using a fifty percent mixture of Jaguar Premium Cooling System Fluid or equivalent, meeting Jaguar specification WSS M97B44-D and fifty percent water.
  20. Install the coolant expansion tank pressure cap.
