Filling Coolant
WARNING: This page is about a different variant/trim than selected.
WARNING:
Caustic fluids
- Danger of chemical burns
- → Wear personal protective gear.
- → Ensure that there is good ventilation.
- → Avoid contact with caustic fluid.
- → If you do come into contact, wash off immediately with plenty of warm water and contact a doctor if necessary.
Information
- Only use Genuine Porsche coolant.
- Never mix coolant with other coolants.
Information
- If no vacuum is built up, there is a leak in the cooling system or the connection pressure is too low.
- Deformation of the rubber hoses in the cooling system is normal.
- When the pressure gauge pointer is in the green area of the display scale, a sufficient vacuum has been built up.
- If both shut-off valves are closed and the compressed air supply is disconnected, the vacuum must not drop.
- If the vacuum drops within approx. 30 seconds, there is a leak in the cooling system.
Information
- A hissing sound after connecting the compressed air supply is normal.
The > 9696 - filling device is used for vacuum-filling.
The > VAS 6096/2 - Vacuum pump is also required in order to increase the vacuum.
- Check the pressure level in the compressed air system and set it to at least 8 bar if necessary.
Information
- The quantity of coolant available should exceed the amount required to fill the system by about 2 litres in order to prevent air being sucked in.
- An antifreeze content of -35°C corresponds to a mixture ratio of 50:50 (coolant/water).
- Place a canister with a sufficient amount of coolant and with an antifreeze content of -35°C behind the vehicle at the same height as the reservoir.
- >VAS 6096/2 - Vacuum pump
must then be connected to the power supply and switched on.
Empty the overflow tank if there is coolant in the overflow tank.
- Push the filler hose -2-
of the vacuum gauge onto the canister connection. Drain the return hose -4-
from the Venturi nozzle into a second empty container.

- Return hose
- Canister for return hose
Information
- The pressure level in the workshop compressed air system must be at least 8 bar.
- >9696/2 - Filling adapter-1- with flexible extension (FZ 100) -2-
for vacuum-filling must be screwed onto the coolant reservoir.
- 5.1 Close both shut-off valves (90° with respect to flow direction). Connect vacuum gauge -3- to the flexible extension -2- .
- 5.2 Connect pressure hose -4- to the Venturi nozzle -5- .
- 5.3 Set the pressure level on the workshop pressure system to 8 bar.
Coolant filling device connections
- Open both shut-off valves on the vacuum gauge until the transparent filler hose is completely filled with coolant.
There must be no air in the filler hose!
Shut-off valves open
- Close the shut-off valve -arrow-
on the filler hose connection to allow a vacuum to build up.
A sufficient vacuum has built up in the cooling system when the pointer is in the green area.

Vacuum built up (pointer in green area)
- Check the cooling system for leaks.
To check the system for leaks, a constant vacuum must be present for 15 seconds!
- 8.1 Close shut-off valve -2- for the Venturi nozzle.
- 8.2 Disconnect compressed air hose -4- .
Shut-off valves closed
Information
- When using the electric vacuum pump > VAS 6096/2 - Vacuum pump , always comply with the following instructions:
- Monitor the overflow tank before and while using the electric vacuum pump and empty the tank in good time.
- There must be no coolant in the connecting hose from the overflow tank to the pump - fluid in the pump will damage it irreparably.
- The electric vacuum pump must not be used for more than 5 minutes, otherwise the coolant can evaporate in the system.
- >VAS 6096/2 - Vacuum pump
must be connected to the Venturi nozzle.
Do not use electric vacuum pump for more than 5 minutes!
- 9.1 Open shut-off valve at the Venturi nozzle for the pump connection.
- 9.2 Check the amount of coolant in the overflow tank while using the electric vacuum pump!
- 9.3 Switch off the electric vacuum pump after 5 minutes and close the shut-off valve at the Venturi nozzle.
- 9.4 Disconnect connecting line from the electric vacuum pump to the Venturi nozzle.

Arrows Shut-off valves
- The pointer -1-
on the pressure gauge -2-
is approx. 5 mm below the end mark of the green area -arrow-
.
Result: Vacuum is OK!

- Check the cooling system for leaks again.
To check the system for leaks, a constant vacuum must be present for 15 seconds!
- To fill the system, open the left shut-off valve (right valve remains closed -arrow-
).
Filling the cooling system - opening shut-off valve for filler hose
- The filling process is complete when the pointer on the pressure gauge stops at zero. Then open the right shut-off valve.
- Remove filling device and collect emerging coolant.
- Bleed the cooling system using the PIWIS Tester .
- Check engine coolant level and correct it if necessary.
