The pressure of the working fluid is created by a pump driven by the vehicle's engine. The hydraulic pump has built-in safety and bypass valves. The safety valve does not allow the liquid pressure to increase above the set value, the bypass valve bypasses excess liquid to the drain.
The reservoir contains the fluid necessary for the power steering to operate. There is a liquid cleaning filter in the tank.
When performing any work on the power steering, it is necessary to keep the following in mind:
- if necessary, the car can be lifted and placed on stands
- the vehicle must be securely fastened
- if necessary, one or both wheels are removed
- before removing the wheels, it is necessary to mark their position relative to the hubs

When hoses and pipelines are disconnected, liquid leaks out. Place a container underneath to collect any leaking liquid.
When assembling hose connections and pipes, ensure that the hoses are not kinked or twisted. Also ensure that pipes and especially hoses do not come into contact with high temperature areas or rotating parts.
Clamps, gaskets and similar parts must always be installed new.
After assembling the system, fill it with liquid and remove air from the system.
Use only fluids recommended by Opel.
After assembly, start the engine and check the system for leaks. Leaks are always visible by the traces of drops on the ground under the car.
