- Do not grasp hot or rotating parts

9 Engine ON
10 Increase engine speed to approx 1000 rpm
11 Close throttle valve (039a) and check the maximum operating pressure

CAUTION: Test should only be conducted briefly to ensure that the oil temperature does not rise beyond its permitted level.

12 Engine OFF
13 Extract oil from power steering pump supply reservoir
14 Connect tester (039)
15 Remove connecting pipe (040a) and connecting hose (040c)
16 Check O-ring on high-pressure line (30i) and replace if necessary
17 Connect high-pressure line (30i) to power steering pump
18 Screw bracket (arrow) for high-pressure line (30i) onto air conditioning compressor
