Caution: Do not start the engine if the power steering fluid reservoir is empty.
Note: at low temperatures (below -20°C) extraneous noise ("crunch") may appear from the power steering pump. If this extraneous noise disappears during engine warm-up, then the power steering is in good working order, and the noise is related to the properties of the working fluid.
1. Checking the fluid level.
- a) Make sure the ignition switch is in the "OFF" position.
- b) Check the fluid level in the power steering hydraulic system reservoir using the marks on its walls. The fluid level should be between the "MAX" and "MIN" lines.
- Working fluid: PSF-3
2. Checking the power steering hydraulic system.
- a) Place the vehicle on a level, horizontal surface.
- b) Start the engine and set the idle speed. With the vehicle stationary, turn the steering wheel several times in a row until the working fluid temperature rises to approximately 50-60°C.
- c) With the engine idling, turn the steering wheel several times to the right and left until it stops.
- d) Check for cloudiness or foaming of the fluid in the booster system reservoir.
Note: If foaming or emulsification occurs, bleed the power steering system.
- d) Check the difference in fluid levels in the power steering system reservoir with the engine running and not running.
- Maximum increase in liquid level: 5 mm
Note:
- If the fluid level changes by more than 5 mm or increases sharply after the engine is stopped, it is necessary to remove air from the hydraulic booster system.
- If air gets into the power steering hydraulic system, extraneous rattling noises will occur from the power steering pump and fluid flow control valve, which will lead to a reduction in the service life of the pump and other components of the hydraulic system.
