How to test car Power Steering Pump ?

Hello everyone, this news mainly describes how the power steering pump self-checks whether it is good or bad. Mainly based on the following four ways, let us understand it together:
1. The noise increases during steering, and the power pump is poorly lubricated in the cold car, resulting in internal wear and abnormal noise;
2. When steering, the steering wheel is stuck, and the booster pump is leaking oil, which causes the oil level to be too low;
3. The steering wheel becomes heavier when turning, which is caused by the oil leakage of the booster pump;

4. Inaccurate pointing occurs when turning.

Hope it can help you!
