9. Release clips and remove air intake hose from 

air cleaner housing.

Note: Pre 03 MY air intake hose illustrated.

10. Discard intake 'O' ring and move intake aside 

for access.

11. Loosen union securing high pressure pipe to 

PAS pump and release pipe.

12. Fit adaptor LRT-57-034A to high pressure port 

of PAS pump.

13. Fit adaptor LRT-57-035 to existing high 

pressure hose.

14. Fit hose LRT-57-002/3 to each adaptor.
15. Fit pressure gauge LRT-57-005 to test valve 

LRT-57-001

16. Connect hoses LRT-57-002/3 to LRT-57-001 

and tighten unions.

17. Hang pressure gauge in a safe position under 

bonnet.

18. Remove PAS reservoir filler cap, fill to level 

indicator and refit cap.

19. Connect battery earth lead.
20. 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 and test equipment are 

free from leaks.

22. Maintain maximum fluid level during test.
23. Open the test valve on LRT-57-001  and start 

the engine.

24. With the engine at idle, slowly turn the steering 

wheel and hold on full lock.

25. Note the pressure reading on LRT-57-005.
26. 
Repeat the pressure check for the opposite full 

lock.

27. Test pressure should be between 21 and 62 

bar, (300 to 900) psi. Dependant on road 
surface.

28. With the engine at idle, centralise the steering 

wheel. Pressure should read 7 bar (100 psi) or 
below.

29. Pressures outside the above tolerance 

indicates a fault.

30. To determine if fault is in steering pump or 

steering box, close the valve on LRT-57-001 for 
a maximum of 5 seconds. Pump damage may 
occur if test valve is closed for longer periods.

31. If gauge does not register between 75 and 103 

bar, (1500 psi), (maximum pump pressure), the 
pump is faulty.

32. If maximum pump pressure is correct suspect 

the steering box.
