1. The system includes a nutrient tank (installed between the right front suspension strut and the bulkhead) big (pressure) the hose from which goes to the pump. A sealed line from the pump goes through a large diameter pressure hose to the connection in front of the steering gear (which contains the pressure sensor on early carburetor and Turbo models) and from there through a metal pipe to the steering gear housing. Two long metal tubes run from the steering gear housing to connectors on the gear housing tube on each side of the rack travel cylinder.
2. The return, from the steering gear housing to the reservoir, is a long metal pipe, installed on the inner wing group and connected at each end to a short flexible pipe.
3. Before removing the reservoir, drain the liquid into a clean container. Disconnect the hoses. Installation is carried out in reverse order. Fill the system with liquid, bleed air from the system.
4. To drain the fluid, disconnect the short flexible tube from the steering gear housing and drain the fluid into a suitable container. To speed up the process, connect a long plastic tube to the steering gear bushing and lower the other end into a container. Start the engine and at idle speed, rotate the steering wheel from lock to lock until all the fluid has drained. Stop the engine to avoid damaging the pump.
5. When installing the reservoir, check that the hose or tube is positioned correctly.
6. To check the pressure sensor, if equipped, disconnect the switch wires and connect a multimeter (in resistance measurement mode), to the sensor terminals. There should be no short circuit (that is, the resistance is infinite). Start the engine and set the idle speed, then turn the steering wheel completely from left to right. When the pressure rises above 1961-2942 kPa, at the maximum steering angle, the switch contacts should close. If not, the switch is faulty and must be replaced.
