Bleeding the hydraulic system of the power steering is necessary after any work related to the depressurization of the system (replacement of the pump or pipelines)
A sign of air in the system is the steering wheel wedging when you try to turn it sharply.
In addition, the pump makes an increased noise when the steering wheel is turned, and the fluid in the reservoir usually foams.
Apply the parking brake to the vehicle and place chocks under the rear wheels.
Raise the front of the vehicle and support it securely so that the front wheels are off the ground.
With a lift, the entire vehicle can be lifted.
Fill the working fluid into the power steering system to the lower mark on the dipstick installed in the reservoir cap
Without starting the engine, turn the steering wheel five to six times to the left and right until it stops.
Start the engine and turn the steering wheel all the way to one side. Do not increase engine speed above idle speed.
Do not hold the steering wheel in the end position for more than 5 seconds.
Turn the steering wheel all the way in the opposite direction.
Return the steering wheel to center position and stop the engine.
Check the hydraulic fluid level in the power steering reservoir and top up if necessary.
When the engine is warm, the level of the working fluid in the tank should be no higher than the upper mark on the dipstick, and when it is cold, not lower than the lower mark.
Repeat steps 4-7 until the fluid level in the reservoir stops decreasing when you turn the steering wheel and air bubbles stop appearing in the fluid.
Add the required amount of working fluid. Do not overfill liquid above the top mark.
Lower the front wheels to the ground. Start the engine and make several full turns of the steering wheel from one extreme position to the other.
Make sure that the difference in fluid levels in the reservoir between left and right turns of the steering wheel is negligible.
Check that the difference between the working fluid level when the engine is running and the level after stopping the engine is within 5 mm.
If the level difference reaches 5 mm or more, it means that the air is not completely removed from the system and the pumping should be repeated.
Replace the reservoir cap and wipe off any drips.
Replacing the power steering fluid
According to the manufacturer's recommendation, the fluid in the power steering system is not changed during the entire service life of the vehicle.
However, if the fluid in the reservoir is very dirty or darkened, then it should be replaced.
If the fluid is heavily soiled or darkened, check the serviceability of the power steering pump and steering gear. They may need to be repaired or replaced.
Raise the front of the vehicle and support it securely so that the front wheels are off the ground.
With a lift, the entire vehicle can be lifted.
Pump out (for example, with a syringe or rubber bulb) fluid from the power steering reservoir.
We unscrew the nut of the tightening bolt of the tank mounting bracket and remove the bolt from the bracket hole
We take out the tank from the bracket, loosen the clamp of the fluid return hose and disconnect the hose
Dip the end of the disconnected hose into a prepared container.
If the hose is not long enough, extend it with a piece of any hose of a suitable diameter.
Drain the power steering system by running the engine two or three times for a few seconds and at the same time turning the steering wheel alternately in both directions until it stops.
Connect the fluid return hose to the power steering reservoir.
Fill the reservoir with fluid and bleed the air from the power steering system
Do not overfill above the upper mark on the dipstick.
Replace the plug and wipe off any drips.
