Power steering pump,
reservoir and hydraulic fluid
circuit

Notes:

Power steering pumps cannot be repaired. If
problems in the pump are suspected carry out
pressure and leakage tests. Replace the pump
if it is malfunctioning.
Check steering system for leaks if the fluid level
in the reservoir is low.
If there are leaks at the line connections first
tighten connections, wipe dry and then re-check
for leaks.

Hydraulic system fluid capacity: 0.7-0.9 Liters
(12-15 oz.)

CAUTION!
Pumps supplied as replacement parts are not
filled with fluid. Therefore it is essential to fill
the pump with hydraulic fluid G 002 000 and
to rotate pump several times by hand.
Otherwise the pump may be damaged or be
noisy during operation.
Part numbers are listed here for reference
only. Always check with your Parts
