Caution: Do not start the engine if the power steering hydraulic reservoir is empty.
Note: at low temperatures (below -20°С) possible extraneous noise ("crunch") from the power steering pump. If during the engine warm-up this extraneous noise disappears, then the power steering is in good condition, and the noise is related to the properties of the working fluid.
1. Checking the fluid level.
- A) Make sure the ignition key is in the "OFF".
- b) Check the fluid level in the power steering hydraulic reservoir according to the marks on its walls. The liquid level must be between the lines "MAX" And "MIN".
- Working fluid: PSF-3
2. Checking the hydraulic system of the power steering.
- A) Park the vehicle on a level, level ground.
- b) Start the engine and set the idle speed. With the vehicle stationary, make several turns of the steering wheel in a row so that the temperature of the working fluid increases to approximately 50-60°C.
- V) With the engine idling, make several turns of the steering wheel to the right and left until it stops.
- G) Check for cloudiness or foaming in the booster system reservoir.
Note: If foaming or emulsification is present, bleed the power steering system.
- d) Check the magnitude of the difference in fluid levels in the booster hydraulic system reservoir with the engine running and not running.
- Maximum liquid level increase: 5mm
Note:
- If the liquid level changes by more than 5 mm or rises sharply after the engine is stopped, then it is necessary to bleed air from the booster hydraulic system.
- If air enters the power steering hydraulic system, there will be extraneous rattling noises from the power steering pump and fluid control valve, which will shorten the life of the pump and other components of the hydraulic system.
