The power steering oil in a special liquid in power steering pump of the power steering system. With the function of hydraulic, it makes the steering wheel easy to turn. Besides, it makes the driver control the direction more convenient. However, some drivers say that there is abnormal sound after changing the oil. While some drivers say that it’s hard to turn the steering wheel. Next let me answer you such questions.
Why there is abnormal sound
After changing the steering oil, you have to discharge the air inside the pump. But if you don’t, there will be strange sound. While this strange sound is because there is air mix in the system. But if there is still abnormal sound after discharging the air, you have to change the power steering oil. Otherwise it will speed the wear on the pump and steering gear box. Besides, it could also be the problem on steering oil. Maybe you add the ATF (automatic transmission fluid). It’s true that part of the cars can add such oil, but we OrientFlex suggest you add the power steering oil. Because it has stable shearing resistance. Therefore, you should judge what’s the problem is. If you can’t, go to the store to repair it.
What to do that it’s hard to turn the steering wheel after changing the oil
Shut down the engine and turn left to the bottom, then turn right to the bottom. There will not be any air left only if repeat such action at least 30 times. After doing this, you will find it easy to turn the wheel.
When change the steering oil, you should start the engine first and then discharge the old oil entirely. Then add new oil but in the meantime, turn the wheel left and right to make the new oil permeate. It also has the clean function. However, you should not turn the wheel too long. Otherwise the high pressure will cause the steering oil erupt out.
