Filter The plastic plate, the two filters and the tank.

Filter The octopus.
The arrow shows the intake for the feed hose.


Drain the used hydraulic fluid into a large plastic container (10-liter paint cans, etc) and put into it metal objects you do not want lying around rusting. For example, a spare hydraulic pump.
Write on the lid what you have put in the container.

Replacing the hydraulic fluid

Replace the hydraulic fluid every 60.000 km, and when you buy yourself a new CX.

Put the car on the lowest level and open the bleed screw. Pump the brake pedal until the pressure is gone. Remove the spare wheel. Remove the mounting bracket on the tank. Lift up the octopus and pull out the two wires. Lift out the tank. Drain the hydraulic fluid. NB! Sharp edges on the tank!

Remove the two filters from the octopus and remove the plastic plate in the bottom of the tank. Clean the tank, plastic plate and both filters with gasoline. Clean the octopus. Then blow dry with compressed air.

Mount both filters (twist the round one in place with a snap) and put the tank back in place (make sure the rubber it is sitting on is where it should be). Fill LHM. Fill the feed tube (arrow) to the hydraulic pump with LHM. Connect the two wires and put the octopus fast but carefully into the tank so that the feed hose don't empty itself, and make sure the half round filter do not fall off or shift. Put on the mounting bracket.

Put your car in normal height and tighten the bleed screw. Start the engine and see that the car rises. Put your car in the bottom position and stop the engine. Open the bleed screw. Start the engine and allow 5-10 minutes at idle to get out air bubbles.

Tighten the bleed screw and lift the car up and down a few times. Check the LHM level. With the car at the highest position the yellow cursor shall be between the two red lines.

Bleed the brakes until clean LHM without air bubbles comes out.

Top up with LHM. With the car at the highest position the yellow marker shall be at the top red line.


LHM+ or LHM PLUS is an improved version of LHM. LHM+ functions better especially at very low temperatures.

LHM+ can be mixed without problems with LHM.

Filter NB! Make sure that this metal bar does not fall off!
(It will disappear down into the engine bay and you'll never find it again.)


The car will not rise after changing the hydraulic fluid:
— Is the bleed screw tightened?
(Tighten the bleed screw.)
— Do the hydraulic pump receive LHM?
(Fill LHM in the feed hose.)
— Is the delivery hose to the hydraulic pump cracked?
(Wrap elastic tape over the cracks, tight.)

Level: The yellow cursor must be between the two red lines when the car is in the top position on a flat surface.
