Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

Plug-In Couplings For Steering Hydraulic System
IMPORTANT:
- The principle of the plug-in couplings for the pressure and return lines is the same. It is the diameter of the plug-in coupling and of the pipelines that differ (return line = large diameter / pressure line = small diameter).
- Plug-in couplings are components that permit simple, fast and precise connection of pipelines.
- These precision components must be handled carefully during repairs. Excess force during assembly work, damage to the sealing surface and soiling can cause leakage.
- Perform preparations carefully when handling plug-in couplings - e.g. cleaning and fitting the plugs - as repairs are possible only by replacing the affected line in most cases. Only the threaded part A (with fitted O-rings) and the holder C are available as individual parts for the plug-in coupling (see Plug-in couplings for pipelines ).

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
