Removing And Installing Hydraulic Pump: Notes
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Porsche Cayenne, 2017 Porsche Cayenne, 2016 Porsche Cayenne, 2015 Porsche Cayenne, and 2014 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Increased risk of accidents and material damage if too much Pentosin CHF 202 is filled in or if Pentosin CHF 202 comes into contact with the coolant hoses when filling or topping up.
- It is possible to overfill the system, causing Pentosin CHF 202 to overflow onto coolant hoses and other components.
→ Before checking the fluid level, run the engine for approx. 20 seconds. Multiple steering operations (maneuvering) will change the fluid level in the reservoir! Check the fluid level.
→ If coolant hoses come into contact with Pentosin, clean them thoroughly with water IMMEDIATELY.
→ Replace visibly swollen coolant hoses.
Information
- Damage to the power steering will occur if there is a shortage of oil in the hydraulic system. Even small leaks can cause the hydraulic fluid to escape and damage the power-steering pump as a result of high oil pressure in the hydraulic circuit.
- Grunt-like noises that can be heard when the steering is locked, or foam formation in the reservoir indicate a shortage of oil and/or that air has also been sucked in. Before filling the reservoir, any existing leaks must be eliminated on the suction side. Alternatively, the defective part on the pressure side should be replaced.
Information
- Before installing a new reservoir, the steering system must be flushed following repairs. → 489729 FLUSHING THE STEERING SYSTEM
- The reservoir must always be replaced if individual or multiple components, such as the hydraulic pump (tandem hydraulic pump) and steering, are replaced.
- The hydraulic system must be bled after repair work is carried out. The vehicle must be lowered onto the wheels for this. → 4890IN TEST AND ASSEMBLY WORK ON POWER STEERING
- Only use Pentosin CHF 202 to fill the hydraulic system.
- Check the hydraulic fluid level.
- Replace sealing rings.
- Observe correct tightening torques. → 4X00IN TIGHTENING TORQUES FOR STEERING
