1. If, when performing any operations, you disconnected the hydraulic hoses of the power steering system, the system must be bled in order to remove all air from it and achieve the required power steering.
2. With the wheels so that they are pointing straight ahead, check the hydraulic fluid level in the pump reservoir and, if necessary, add the recommended type of hydraulic fluid (see relevant chapter), so that its level rises to the Cold mark on the dipstick.
3. Start the engine and leave it to idle at high speeds. Check the hydraulic fluid level again and add more if necessary to keep the hydraulic fluid level at the Cold mark on the dipstick.
4. Bleed the power steering system by turning the wheels from side to side several times, do not turn the wheels all the way. This will purge air from the hydraulic system. When bleeding, make sure that the hydraulic fluid reservoir on the pump is full.
5. After the air has been bled from the system, set the wheels so they are pointing straight ahead and let the engine run for a few more minutes before shutting it off.
6. Drive the car and check the operation of the steering and the absence of extraneous noise when the steering wheel is turned.
7. Check the hydraulic fluid level, it should be at the Hot mark on the dipstick when the engine is warmed up to normal operating temperature. Add hydraulic fluid if needed (see relevant chapter).
