Porsche recommends to vent the system after each session and to change the fluid
after each race weekend.
Venting:
•
Depress the clutch pedal 2 to 3 times and keep it depressed
•
Shortly open the vent valve (illustration 2.2.3.1) – the clutch pedal has to be
depressed and should not be released
•
Close the vent valve again
•
Repeat this procedure 2 to 3 times
•
Check the fluid level on the fluid reservoir
and replenish fluid, if required
Replacement:
•
Remove the old fluid from the reservoir and fill with new fluid
•
Then proceed as for venting, perform approx. 10 times the steps
mentioned above and replenish fluid in the reservoir if required.
