What is the reason for the noise when turning the steering wheel for the first time in a cold car?

The reason for the noise when turning the steering wheel for the first time in a cold car is only one, which is generally abnormal lubrication of the power steering pump when the car is cold. Additionally, it is necessary to check whether the level of the power steering fluid is normal, whether the return power steering pipe is leaking, and the level of the power steering fluid. Steering refers to changing the direction of the car by using the steering wheel. Overview of the car steering wheel: The steering wheel, also known as the car's wheel, is a wheel-like device used to control the direction of movement in cars, engineering machinery, agricultural vehicles, etc. The steering wheel is generally connected to the steering shaft via splines. Usage of the car steering wheel: The driver controls the steering wheel to maintain or change the direction of the car's movement according to the driver's intention. When a frontal collision accident occurs, whether due to the rearward movement of the steering wheel or the driver's forward collision with the steering wheel, the driver can be injured.
I've encountered this issue several times. Since I usually pay close attention to car maintenance, I found that the first turn when the car is cold often makes a noise, mostly due to low or leaking power steering fluid. Think about it, when the engine is cold, the oil is thick, and the steering pump doesn't have enough pressure, causing a squeaking sound when turning, and in severe cases, it may even struggle to turn. Another common reason is aging or loose steering belts. In winter, the low temperature causes metal to contract, and the belt tension becomes insufficient, resulting in a clicking sound when turning. If these small issues are ignored, the steering system will wear out faster, making the steering wheel feel heavy over time, and even posing safety risks. I recommend checking the power steering fluid reservoir level before each start. If it's low, add the appropriate fluid. If that doesn't help, consult a professional technician to check the seals or pipelines—safety comes first. Regular maintenance can also save a lot on repair costs, so don't wait until a major problem arises to take action.
