Extract oil from expansion reservoir of power steering pump


Before opening the hydraulic system the area around the separation point should be cleaned thoroughly.
Otherwise even the smallest dirt particles, introduced into the hydraulic system, can lead to malfunctions and total failure of the hydraulic system.

 Danger !

Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.

Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.

7

Allow engine to run at a speed of approx. 1000 rpm

8

Close throttle valve and check oil pressure


Run check for brief period only.
This is to prevent the oil temperature from rising to an impermissible level.
