2. Plug the pump openings with suitable plugs.
3. Connect the special plug to the hand vacuum pump.
4. Install the plug in place of the pump reservoir cap.
5. Create a vacuum in the tank of about 68 kPa, but no more.
6. If the vacuum drops again, repair or replace the pump. If vacuum remains constant, check other parts of the power steering system.
7. Observe the condition of the liquid in the tank.
Attention: the liquid should not foam or bubble. Intermittent air bubbles indicate a bad hose connection or damaged hose o-rings.
8. If foaming occurs, replace the following parts:
- return hose clamps;
- return hose sealing rings;
- pressure hose sealing rings;
- steering tube seals;
- O-ring between reservoir and pump.
9. Bleed the power steering system.
10. Make a test drive for about 20 km to warm up the fluid in the system. Park the vehicle on a level, level surface.
11. Verify that the following conditions are met:
- there is a smooth operation of the amplifier;
- the car adequately responds to the movement of the steering wheel;
- a constant liquid level is maintained in the pump reservoir;
- there are no fluid leaks;
- the liquid does not foam and does not change color.
