911 Turbo AWD F6-3600cc 3.6L SOHC Twin Turbo (1997)
Power Steering Fluid: Testing and Inspection
The reservoir is fitted on the right in the engine compartment.
Check the fluid level* with the engine idling and without operating the steering system. Correct fluid level:
In the case of reservoirs with a transparent upper section (first version used), the fluid level must be between the min. and max. marks on the reservoir.
If the reservoir does not have a transparent upper section, the level must be between the two marks on the dipstick attached to the lid. Unscrew the lid
and wipe the dipstick clean. Screw the lid back on, remove it again and check the fluid level.
Footnotes
(*) Porsche started to fill the hydraulic brake booster and power steering systems with Pentosin CHF 11 S (green) in March 1996.
-
ATF was used before then.
-
Pentosin and ATF are miscible (can be mixed together).
-
This means that Pentosin can be used to top up the fluid level in 993 vehicles produced before the aforementioned introduction date.
-
On vehicles filled with Pentosin, always fill or top up the brake system with Pentosin.
