Hydraulic power-assisted steering

When the engine is shut-down, power assistance to the steering is lost and be-
tween 5 and 7 times as much effort is needed to turn the steering wheel. In gen-
eral, if loss of assistance is experienced, proceed as follows: Check the fluid level
in the reservoir, check for leaks from hose and pipe unions and rectify if possible
(tighten the unions or change the hoses). Top up the reservoir with clean fluid to
the recommended specification. Restart the engine and check that the pump
performs normally. Test at low engine and road speed.
If any doubt remains concerning the pump's efficiency, the unit must be inspect-
ed by an approved specialist.
Under no circumstances must hydraulic components be removed or their initial set-
tings altered. This work must be carried out by a specialist.
A hydraulic system can only operate efficiently if it is kept perfectly clean. Great care must
therefore be taken to ensure that no dirt enters the system when the above operations are car-
ried out.
