Check steering with hydraulic booster
Check of effort steering | PERFORMANCE ORDER | | 1. On the car standing on a firm, level surface, set the front wheels to straight-line motion. | | 2. Start up the engine and warm up the power steering fluid to a temperature of 50 ~ 60 ?� C. Turn the steering wheel from lock to lock several times. |  | 3. Leave the engine to operate at idle speed and hook on a dynamometer for a steering wheel spoke in a place the most remote from the center of the wheel. With the front wheels established for rectilinear movement measure effort, which must be applied to the steering wheel to turn the wheel left and right. Force: 31 N (3.2 kg) | | 4. If the measured force is greater than the desired value, check the fluid level, the lack of air in the fluid leaks in hoses and their connections, the work of the power steering pump and steering gear, and pressure in the tires of the front wheels. |

Check the fluid level
A warning  The hydraulic power-assisted steering add only the recommended liquid.
| PERFORMANCE ORDER |  | 1. Make sure that the liquid level is between labels FULL (full) and LOW (low) located on the body of a transparent tank. | | 2. If necessary, add or pump fluid from the reservoir. |
|
Bleeding the hydraulic system of the power steering
A warning Do not start the engine. Lift the front of the car and fix on supports.
| PERFORMANCE ORDER | | 1. Check the fluid level. | | 2. With the engine off, turn the steering wheel from lock to lock several times. | | 3. Check the fluid level. If the fluid level has dropped, add more liquid. | | 4. Repeat steps 2 and 3 until the liquid level is not stabilized. | | 5. Start up the engine and leave to work on frequency of rotation of idling |  | 6. Turn the steering wheel from lock to lock several times. | | | 7. Make sure that the liquid does not foam, and its level has not gone down. | | 8. If necessary, add a liquid and repeat steps 6 and 7. |
|
Check for fluid leaks | PERFORMANCE ORDER | | 1. Start up the engine. | | 2. Turn the steering wheel from lock to lock several times to pressurize the hydraulic power steering. | | 3. Check for fluid leaks from hydraulic power steering. |
A warning To avoid damage do not hold the steering wheel is turned fully over 15 seconds. Leaks of a liquid are available in most places of connection of hoses and tubes, as well as in the places of their connection to a tank and steering gear.

Checking the fluid pressure in the hydraulic system | PERFORMANCE ORDER |  | 1. Assemble the device for measurement of pressure OK201 323 AA0 as shown. Torque: 39-49 N ??? m | | 2. Disconnect the pressure hose from the pump and connect the device for measurement of pressure OK201 323 AA0 between a hose and a pump. |
A warning Before disconnecting the hose, put labels for correct its repeated installation.
| | 3. Remove air from hydraulic power steering. |  | 4. Open the valve device OK201 323 AA0. Start up the engine and turn the steering wheel from lock to lock several times to warm up the power steering fluid to a temperature of 50 ~ 60 ?� C, |
A warning If the valve is left closed for more than 15 seconds, the liquid temperature will increase excessively and will damage the oil pump.
|  | 5. Close the valve. Increase the engine speed to 1000-1500 min -1 and measure the fluid pressure generated by the pump. If the pressure is lower than required, replace the power steering pump. The fluid pressure generated by the power steering pump: 7358-7848 kPa | | 6. Open the valve and increase the engine speed to 1000-1500 min -1. | | 7. Turn the steering wheel from stop to stop several times and measure the fluid pressure generated by the gear pump. If the pressure is lower than required, replace the power steering pump. The pressure of a liquid created by gear pump of the amplifier: 7358-7848 kPa |
A warning If you leave in the full lock position for longer than 15 seconds, the liquid temperature will increase excessively and will damage the oil pump.
| | 8. Remove the device for measurement of pressure OK201 323 AA0. Replace and tighten the pressure hose. Tighten the hose connection to torque. Torque: 39-49 N ??? m |  | 9. Remove air from hydraulic power steering. |
