Removal
1. Disconnect the negative battery cable (chapter 5 paragraph 1).
2. Disconnect the electrical connector of the hydraulic steering system pressure sensor (see Fig. 34.2).
Models with 4-cylinder engines
3. Unscrew the bolt securing the pipeline to the engine lifting bracket located on its right side.
4. Unscrew the bolt securing the pipeline support to the pump bracket.
5. Place a container under the pump to catch any drips.
6. Loosen the clamp and disconnect the hose supplying the liquid to the pump from the inlet pipe. Plug the hose to prevent dust and dirt from getting in.
7. Unscrew the discharge pipe connection nut. The liquid should flow into the container.
8. Apply the parking brake, raise the front of the vehicle and place it on supports. Remove the right front wheel.
9. Remove the bolts and lower accessory drive cover.
10. Using a wrench, turn the accessory drive belt tensioner clockwise to remove the belt tension. Then remove the belt from the pulleys (see chapter 1).
11. Remove the four bolts and lift the pump off its brackets. To access the bolts on the right side of the engine, rotate the pump pulley so that the pulley hole axes line up with the bolt axes.
Models with V-shaped 6-cylinder engines
12. Unscrew the bolt securing the pipeline to the right engine support.
13. Place a container under the pump to catch any drips.
14. Loosen the discharge line connection nut located in front of the right engine support. The fluid should drain into a container.
15. Disconnect the drain hose from the fluid pump located behind the engine mount. Plug the hose to prevent dust and dirt from getting in.
16. Before removing the engine support, you need to support it on the right side using a lift. If you are using a jack for this, install it under the pan, placing a reliable wooden pad between them.
17. Release the high-voltage wire retainer. Then, with the engine suspended, gradually loosen the 6 nuts securing the upper part of the right engine support. Remove the support from the studs (see Fig. 34.17).
18. Drain the cooling system (chapter 1). To prevent fluid leaks, disconnect the hoses from the reserve tank of this system.
19. Disconnect the fluid level sensor connector on the tank.
20. Unscrew the bolts and remove the tank.
21. Unscrew the bolts and remove the lower part of the right engine support from the inside of the wing (see Fig. 34.21, a, b).
22. Holding the pump pulley with an Allen key, unscrew the four pulley bolts without removing them (see Fig. 34.22).
23. Apply the parking brake and loosen the right wheel nuts. Remove the front wheel.
24. From under the wheel arch, remove the screws of the front and rear sections of the accessory drive belt cover.
25. Using a suitable tool, turn the accessory drive belt tensioner clockwise to remove tension from the belt. Then remove the belt from the pump pulley.
26. Remove the pump pulley bolts and remove the pulley (see Fig. 34.26).
27. Loosen the pump pipe bracket bolt and move the bracket to the side.
28. Unscrew the five nuts and two bolts securing the pump plate (see Fig. 34.28).
29. Unscrew the two pump mounting bolts and remove the pump together with its plate from the engine (see Fig. 34.29, a-c).
Installation
30. If necessary, the sealing ring on the discharge side of the pump can be replaced (as described in paragraph 30).
Models with 4-cylinder engines
31. Install the pump on the bracket and secure it with four bolts, tightening them to the required torque.
32. Place the accessory drive belt on the pulleys. Then turn the belt tensioner clockwise until the tensioner pulley contacts the belt. Release the tensioner to tighten the belt.
33. Install the lower belt cover.
34. Install the right front wheel and lower the vehicle to the ground.
35. Connect the pump discharge line and tighten the line nut.
36. Connect the liquid supply hose to the pump with the branch pipe and tighten the clamp.
37. Install the pipeline support onto the pump bracket and tighten the bolt.
38. Install the pipeline support on the engine lifting bracket on its right side and tighten the bolt.
Models with V-shaped 6-cylinder engines
39. Install the pump together with its plate and tighten the bolts and nuts to the required torque.
40. Install the pipe bracket and tighten the bolt.
41. Install the pump pulley and tighten the bolts to the required torque, holding the pump shaft with an Allen key to prevent it from turning.
42. Inspect the belt. Replace it if necessary. Place the accessory drive belt on the pulleys. Then turn the belt tensioner clockwise until the tensioner pulley contacts the belt. Release the tensioner to tighten the belt.
43. Install the accessory drive belt covers. Install the wheel. Lower the vehicle to the ground and tighten the wheel nuts to the specified torque.
44. Install the lower part of the engine mount and tighten the bolts to the specified torque (Chapter 2A or 2B).
45. Install the reserve tank from inside the wing. Reconnect the wiring and hoses.
46. Install the upper part of the engine mount onto the studs. Tighten the 6 nuts to the specified torque (Chapter 2A or 2B). Fix the high-voltage wire.
47. After installing the engine mounts, remove the lift.
48. Connect the drain hose and the discharge pipe to the pump, tighten the fitting to the required torque.
49. Install and tighten the pipeline mounting bolt to the engine mount.
50. Fill the cooling system (chapter 1).
All models
51. Connect the negative battery cable.
52. Bleed the hydraulic system (paragraph 33).
