Checking Fluid Level For Power-Assisted Steering

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2013 Porsche 911, 2012 Porsche 911, 2011 Porsche 911, 2010 Porsche 911, and 2009 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

The reservoir is located in the engine compartment.

For your information: Unlike on other Porsche models, Pentosin is also used as the clutch control medium for the 911 Turbo. This additional Pentosin reservoir -2- for the 911 Turbo with manual transmission is located under a cover in the luggage compartment.

Check the fluid level for power-assisted steering.

There are two marks on the dipstick located on the cap (911 Carrera, 911 GT3 and 911 Turbo). One area is marked "Cold" for when the engine is cold → "Cold" mark: approx. 20°C and the other is marked "Hot" for when the engine is warmed up → "Hot" mark: approx. 80°C.

Check the fluid level (Pentosin) when the engine is idling and cold → "Cold" mark: approx. 20°C.

Start the engine and let it run for → Period: approx. 20 s. Switch off engine.
Open engine cover. Open reservoir cap.
Wipe off the dipstick. Close and then reopen cap. The fluid level should lie in the hatched area beneath the "Cold" mark (mark = maximum level) at → "Cold" mark: approx. 20°C. Top up with Pentosin if necessary. The higher mark "Hot" is for a fluid temperature of → "Hot" mark: approx. 80°C.

Do not add too much Pentosin! The respective marks are for the maximum fluid level at the "COLD" or "HOT" temperature.

If assembly work was performed previously, check fluid level with the engine idling and without operating the steering.

Multiple steering movements (maneuvering) with the engine switched off change the fluid level in the reservoir - fluid level rises. In this case, the engine must be run for at least 20 seconds immediately prior to the fluid level check.

When topping up or filling in Pentosin, make sure that it does not come into contact with the coolant hoses! If coolant hoses come into contact with Pentosin, thoroughly clean them with water IMMEDIATELY! Replace visibly swollen coolant hoses!
