13. Remove bolt from steering box pipe retaining 

clip. Leaving the PAS reservoir oil pipe in place, 
release pipe retaining clip and PAS cooler pipe 
from steering box, discard the seal.

14. Fit tool LRT-57-041 to steering box housing.
15. Fit seal to PAS oil cooler pipe.
16. Fit PAS cooler pipe to LRT-57-041 align the 

retaining clip to pipes and tighten bolt to 24 Nm 
(18 lbf.ft).

17. Connect test hoses LRT-57-002  to LRT-57-

041  and tighten unions. Ensure all pipes and 
fittings are clear of engine rotating parts.

18. Hang pressure gauge in a safe position under 

bonnet.

19. LHD only:  Fit turbocharger intercooler feed 

pipe and vacuum connection and fit PAS 
reservoir to mounting bracket. Fit air intake 
hose to turbocharger and air cleaner and 
connect multiplug to MAF sensor. The above 
parts must be refitted in order to run the 
engine.

20. Fill PAS reservoir, connect battery earth lead. 

Start engine and allow air to bleed from PAS 
system, by turning steering from lock to lock. 
Stop engine and check PAS fluid level.

21. Ensure steering system is free from leaks and 

maintain maximum fluid level during test.

22. Open the test valve on LRT-57-001  and start 

the engine.

23. With the engine at idle and normal running 

temperature, slowly turn the steering wheel and 
hold on lock.

24. Note reading on pressure gauge.
25. Repeat pressure check on opposite lock, again 

noting the reading on the pressure gauge.

26. The test pressure should be between 21 and 62 

bar, (300 to 900 lbf/in

2

.  Pressure will rise to 62 

bar (900 lbf/in

2

)  when held on full lock.

27. With the engine at idle, centralise the steering 

wheel. Pressure should read 7 bar (100 lbf/in

2

) 

or below.

28. Pressure outside the above tolerance indicates 

a fault.

29. To determine if fault is in steering pump or 

steering rack, close the valve on LRT-57-001 
for a maximum of five seconds. Pump damage 
may occur if test valve is closed for longer 
periods.  

30. If the gauge does not register between  75 and 

103 bar, (1500 lbf/in

2

) (maximum pump 

pressure), the pump is faulty.

31. If maximum pump pressure is obtained, 

suspect the steering box.

32. On completion, stop engine, disconnect battery 

earth lead and syphon fluid from PAS reservoir.

33. LHD only:  Disconnect multiplug from MAF 

sensor, remove air intake hose clips and move 
hose aside.

34. LHD only:  Release PAS reservoir from 

mounting, for access to turbocharger 
intercooler pipe.Remove vacuum hose from 
turbocharger intercooler pipe.Release clips and 
disconnect intercooler  pipe from turbocharger.

35. Remove test equipment from tool LRT-57-041.
36. Remove bolt and clip from steering box.
37. Release PAS cooler pipe from tool LRT-57-041  

and discard seal. leaving PAS reservoir oil pipe 
in place, release  tool LRT-57-041 from 
steering box and discard seal.
