Removing hose for power steering (naturally aspirated engine)

CAUTION



- Damage can result from Pentosin getting into the surrounding area (e.g. onto the coolant hoses) when the hydraulic hoses are released (opened).

-> Avoid all contact with Pentosin.
-> Collect emerging Pentosin in a suitable container.
-> Wear protective goggles when carrying out overhead work on lines with Pentosin!
-> Wear protective gloves!
-> If coolant hoses come into contact with Pentosin, clean them thoroughly with water IMMEDIATELY.
-> Replace visibly swollen coolant hoses!





Installation position of hose for power steering

1. Drain Pentosin from the power-steering reservoir using suction. Only draw out fluid using a syringe that is used exclusively for Pentosin.
2. Loosen the line bracket on the hose line

Information

- In vehicles without Servotronic, the hydraulic system must be flushed with approx. two litres of Pentosin.

- The hydraulic system must be bled following repairs -> 48 Test and assembly work on power steering. The vehicle must be lowered onto the wheels for this.

- Only use Pentosin CHF 202 to fill the hydraulic system.

- Pay attention to the hydraulic fluid level.

- Replace sealing rings.

- Observe correct tightening torques. -> 48 Tightening torques for steering

Information

Pentosin in engine compartment

- The reservoir is located at the front left of the engine compartment.

- A dipstick with MAX/MIN markings is mounted on the cap of the reservoir. They are for a fluid level with a cold engine (approx. 20°C).

- The MAX marking can be easily exceeded at higher temperatures.

- Check the fluid level (Pentosin CHF 11 S) when the engine is not running and when it is cold (approx. 20°C).
