Hydroflush

Hydroflush is a blank fluid that is used in a short period as a substitute for the traditional LHM+, which the hydraulic system of you Citroën is normally using. Experience tells us that normal LHM+ is not capable of transporting small particles, smudge and other irregularities through the system and into the filter. After some years and kilometers or miles this can give some smaller problems and irritations such as: heavy steering, height-problems at the rear, unstable height correctors, braking problems, clicking of the hydraulic pump.

The Hydroflush fluid needs to work in the system for a while. Remove the LHM+ from the tank and fill up with the Hydroflush fluid. Drive with this flushing fluid somewhere between 1500 and 5000 kilometers depending on your normal use pattern.
After this, replace the Hydroflush again with LHM+ and the car's hydraulics are as new again.

DIY-howto

To remove the old LHM+ from the tank, follow this procedure:

• Place the hydraulic system of the car in lowest position
• Open the pressure regulator bleed screw on the main accumulator, to release the whole system from pressure.

• Take the lock off the tank, and take away the clip that holds the tank in place (this is a different process for each car type; the pictures are for the CX):
  
• Remove the overflow- or return-filter as well as the main filter from the connecting hoses
• Lift the LHM-container out of the engine compartment and clean it thoroughly
• Take out the plate which is at the bottom of the container (CX only)

Return from the pressure regulator and height corrector 5. Main hose to the high pressure pump 6. Main filter 7. Plate i the bottom of the container 8. Overflow- and return filter 9.

• Clean the container with preferably gasoline and dry it with an air compressor.

When cleaned, put the parts back in place, and pour the Hydroflush fluid in the tank.

In some cases, the system is unable to suck the fluid into the pump because the system is completely empty. The result is that the car will not rise instantly. In this case:

• Separate the hose which goes from the lock of the hydraulic tank to the hydraulic pump and fill the hose with Hydroflush fluid so that the fluid runs into the pump.
• Connect the hose again
• Close the bleed screw on the regulator (see 3)
• Place the height control lever of the car in its highest position and raise the car. Top off the system with enough fluid (see picture)
