Clutch Fluid: Testing and Inspection




Clutch: Checking Fluid Levels

CAUTION:
Danger of material damage if the wrong fluid is used.
- Fill Pentosin CHF 11 S only into both supply tanks.


Pentosin CHF 11 S can be ordered with the following part number:

Quantity supplied 6 litre = 000.043.203.33. Container volume: 1 litre cans (6 ea.).





Power steering and clutch actuation are supported by hydraulic auxiliary forces. A tandem servo pump is available instead of the servo pump for the steering (996 naturally aspirated engine) for this purpose. Both systems share one supply tank (expansion tank). This tank -A- is located in the engine compartment.





In addition, a second supply tank for the clutch actuating circuit is available in the luggage compartment under the cover -A-.


Checking Pentosin CHF 11 S Hydraulic Fluid In the Engine Compartment and Luggage Compartment

NOTE:
- The supply tank for the power steering and the clutch booster circuit is located in the engine compartment.
- The second supply tank for the clutch actuating circuit is secured under a cover in the luggage compartment.


Checking Pentosin CHF 11 S Hydraulic Fluid In the Engine Compartment

NOTE: The dipstick located on the reservoir cap has the "Cold marking" (approx. 20 °C engine temperature) on one side and the "Hot max" symbol on the other side.




Pentosin tank in the engine compartment

- Check the fluid level (Pentosin CHF 11 S) with the engine stationary and cold (approx. 20 °C).

CAUTION:
Danger of damage to property if too much Pentosin CHF 11 S is filled or if it comes in contact with the coolant hoses when topping up or filling in.
- Observe the following specifications in order to avoid overfilling and thus overflowing.
- Multiple steering operations (manoeuvreing) and/or actuating the clutch with the engine switched off change the fluid level in the reservoir. Fluid level rises. In this case, the engine must be run for approx. 20 seconds immediately prior to the fluid level check.
- If coolant hoses come into contact with Pentosin, thoroughly clean them with water IMMEDIATELY.
- Replace visibly swollen coolant hoses.


1. Start engine and run it at idle speed for approx. 20 seconds.
Switch off engine.

2. Open the engine cover.

3. Open reservoir cap.

4. Wipe off the dipstick. Close and then reopen the cap. The fluid level should be in the designated "Cold range" (min./max. level at 20 °C). Top up with Pentosin if necessary. Do not add too much Pentosin. In warmed-up condition, the fluid level must not exceed the "Hot max" mark.


Checking Pentosin CHF 11 S Hydraulic Fluid In the Luggage Compartment

WARNING:
Danger of damage and injury if the wrong fluid is filled in after the caps have been changed.
- If fluid is being filled into several tanks in the luggage compartment (brake fluid/water/Pentosin), carry out these filling procedures in sequence (always screw off just one cap) so that the caps of the 3 tanks are not interchanged. This prevents any chance of another person filling in the wrong fluids at a later stage.

NOTE:

- On right-hand drive vehicles, the supply tank is located in the area of the brake fluid reservoir/control module for automatic headlight beam adjustment (ALWR).
- The fluid level on the transparent supply tank should always lie between the Min. and Max. marking.
- Hold the supply tank by hand (counter) to undo and tighten the cap.
- Pentosin CHF 11 S hydraulic fluid should not be topped up until the fluid level is at the lower marking.





This tank -2- supplies the clutch actuating circuit with Pentosin.





1. Remove cover -A-.




Front tank





2. If the fluid level in the transparent container -2- does not lie between the Min. and Max. marking, screw off the cap. Counter the container when doing this. Fill in Pentosin CHF 11 S hydraulic fluid up to the Max. marking.

3. Screw cap (green) -2- closed. Counter the container when doing this.





4. Install cover -A-.
