Note: If the liquid is heavily contaminated and dark, check the serviceability of the power steering pump and steering gear. Perhaps they need to be repaired.
You will need: container for working fluid, key «at 22», pliers.
For working fluid replacement perform the following operations.
1. Raise the front of the car until the wheels are off the surface of the site and place the car on supports.
2. Remove the fuel pump fuse from the mounting block in the engine compartment.
3. Turn away a stopper of a tank of the hydraulic booster of a steering.
4. Loosen the clamp securing the fluid supply hose to the power steering pump nozzle by squeezing its bent ears with pliers. Slide the clamp along the hose and disconnect the hose from the nozzle. Drain the liquid from the tank into a previously prepared container.
5. Turn out a bolt union of fastening of the pipeline of a high pressure to the union of the pump of the hydraulic booster of a steering and disconnect the pipeline.
6. Drain the fluid from the power steering system by turning on the starter two or three times and turning the steering wheel in both directions until it stops.
7. Attach the pipeline and niches to the power steering pump. fill the fluid reservoir and bleed the air from the power steering system.
The need for pumping arises when air enters the hydraulic system during a fluid change, repair work, or in case of leakage during operation. A sign of the presence of air in the system is the wedging of the steering wheel on the wheels when trying to make a sharp turn. In addition, the pump makes an increased noise when the steering wheel is turned, and the liquid in the tank usually foams.
For hydraulic booster system bleed steering, do the following.
Warning: Air in the power steering system will cause premature failure of the power steering pump.
1. Fill the working fluid into the hydraulic booster system to the minimum level (label «MIN») (see «Checking the level and topping up the working fluid in the power steering reservoir»).
2. Start the engine and turn the steering wheel five or six times in both directions until it stops.
Note: During pumping, add fluid to the tank: its level should not fall below the mark «M1N» on the fluid level indicator on the reservoir cap.
3. Turn the steering wheel from lock to lock in both directions until there are no air bubbles in the fluid filled into the power steering reservoir, and the level of the working fluid in the reservoir stops decreasing.
Note: Make sure that the fluid level in the power steering system reservoir barely changes when the steering wheel is turned to either side. If the fluid level changes by more than 10 mm, and rises sharply when the engine is stopped, re-bleed the system.
