We replace the fluid in the power steering hydraulic system if the fluid is dark and heavily contaminated
If the fluid is heavily contaminated, you need to check the serviceability of the power steering pump and steering gear
To replace the power steering fluid, raise the front of the car until the wheels come off the surface of the site and place the car on supports
We squeeze the bent ears of the clamp for fastening the hose of the return line of the power steering system, slide the clamp along the hose and disconnect the hose from the pump nozzle
We unscrew the fitting of the pressure line of the power steering system and disconnect the pipeline from the pump
Remove the gaskets from the fitting and replace them regardless of the condition
We lower the disconnected drain and pressure pipelines into a previously prepared container
Disconnect the pads with wires from the ignition coils
We 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
We connect pipelines and hoses to the power steering pump
Pour fluid into the reservoir and bleed air from the power steering system
A sign of the presence of air in the system is the wedging of the steering wheel when trying to turn sharply
In addition, the pump makes an increased noise when the steering wheel is turned, and the liquid in the tank usually foams
The presence of air in the power steering system leads to premature failure of the power steering pump
Pour the working fluid into the hydraulic booster system up to the “MAX” mark on the reservoir wall
Disconnect the pads with wires from the ignition coils
Turn on the starter for 10-20 seconds, turn the steering wheel five or six times in both directions until it stops
During pumping, add liquid to the tank: its level should not fall below the filter
Connect the pads with wires to the ignition coils and start the engine
Turn the steering wheel all the way in both directions until there are no air bubbles in the power steering fluid
We make sure that the fluid level in the reservoir of the power steering system practically does not change when the steering wheel is turned in both directions
If the fluid level changes by more than 10 mm, and when the engine stops, it rises sharply, re-bleed the system
