If the power steering system into the air, will cause the automobile steering instability, remittent.

The main reasons for the infiltration of air are: the loosening or damage of the tubing joint, the rupture of the tubing, the reconnection of the tubing or the disassembly to the oil pump, the no exhaust operation after the steering gear, the low liquid level of the tank and so on. Therefore, it is necessary to check the tubing joint or tubing of the Mercedes Benz parts in the north of Baotou, and the exhaust operation must be carried out after the reinstallation of the tubing and the turning of the northern Baotou Benz accessories to the oil pump and the steering gear. The specific operation steps are as follows:

First, turn the steering wheel to the left and right limit position continuously, and add the steering fluid to the North American Benz parts storage tank at the same time.

2. If the liquid level is not maintained, start the engine and turn the steering wheel to the limit for more than 5 times.

(3) stop the steering wheel in the left limit position, unscrew the deflation bolt until the exhaust gas is tightened, then turn the steering wheel to the right limit position, unscrewing the deflation bolt on the steering gear shell, until the net gas is tightened. Repeat the above actions until all the gas is discharged. Attention: the action should be light to tighten the deflation bolt so as not to damage the screw thread of the deflated bolt, and the level of the liquid level in the tank should be paid attention to in the process of deflation, and the steering fluid is added when necessary.

4. Turn the steering wheel on the left or right, the liquid level is not greater than 4mm, and the oil temperature should not change at this time.
