Filling Coolant (Includes Bleeding)

WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
  1. If you have not already done so, screw cap adapter K65 for coolant reservoir onto the reservoir.
  2. Connect the flexible extension (FZ 100) to the cap.
  3. Connect the vacuum pressure gauge of the bleeder tool to the flexible extension. When doing so, ensure that both shutoff valves are closed (positioned at 90° with respect to flow direction).
  4. Connect the Venturi nozzle to the vacuum pressure gauge.

    Information 

    • The coolant amount provided must be approx. 2 litres more than the amount to be filled in. 
    • Because differing quantities of coolant can drain away during different types of repairs, the filling capacity can vary greatly. Recommendation: To be on the safe side, fill the canister to 30 l, then bleed the cooling system. The difference after bleeding is the coolant quantity that is sucked in. Check the volume scale on the canister. 
    • An antifreeze content of -35 °C corresponds to a mixture of 50: 50 (antifreeze: water). 
  5. Place a canister with a sufficient amount of coolant and with an antifreeze content of -35 °C beside the vehicle close to the reservoir.

    Information 

    • The bleeding process is completed more quickly if the canister is positioned at roughly the same height as the coolant expansion tank. 
  6. Push the filler hose -5-  of the vacuum pressure gauge onto the canister connection. Lay the return line -6-  from the Venturi nozzle to a second container (bucket).

    Information 

    • A hissing sound after connecting the compressed air supply is usual. 
  7. Connect the compressed air supply.

  8. Open both shut-off valves on the vacuum pressure gauge. → Shut off valves on vacuum pressure gauge until the transparent filler hose has completely filled with coolant.

  9. Close the left shutoff valve (V1) -arrow-  on the vacuum pressure gauge and allow a vacuum to build up in the coolant circuit.

    Information 

    • If no vacuum is generated (the pointer does not move to the green area), there is a leak in the cooling system. 
    • If a vacuum is still not established, there is a blockage in the tool. Clean the device, use clean compressed air. 
    • Deformation of the rubber hoses of the cooling system is normal. 
    • Pressure of between 6 and 10 bar must be present. The higher the pressure, the better the vacuum in the vehicle cooling system. 
    • When the pressure gauge pointer is in the green area of the display scale, a sufficient vacuum has been built up. 
    • After both shutoff valves on the vacuum pressure gauge have been closed and the compressed air supply has been disconnected, the vacuum must not drop. If the vacuum drops within approx. 30 seconds, there is a leak in the coolant circuit. 
  10. When there is a sufficient vacuum in the cooling system (indicator is in the green area), close the right shutoff valve (V2) and then disconnect the compressed air supply.

  11. Re-open the left shut-off valve (V1) on the vacuum pressure gauge. The cooling system is then filled.
  12. When there is no trace of vacuum present or the coolant is no longer drawn from the canister, open the right shutoff valve (V2).

  13. Then remove the complete filling tool (including the adapter K65).
  14. If necessary, fill the coolant reservoir with coolant to the MAX marking.

  15. If necessary, check to ensure that the cooling system is properly sealed.

  16. Screw on lid on reservoir in a clockwise direction.

  17. Close the maintenance cover.
  18. Re-install the complete engine guard. → Installing engine guard
  19. Conduct a test drive with the vehicle, check the fluid level in the reservoir after the cooling system has cooled again and, if necessary, fill up to the MAX marking with coolant.
