What Causes Engine Noise When Turning the Steering Wheel?
3 Answers
Engine noise can be caused by engine misfire, improper use of engine oil, timing belt noise, insufficient car warm-up time, and other factors. Below is relevant information about the engine: Relatively small friction torque: The engine's valve drive mechanism adopts a hydraulic support roller rocker arm structure. Compared to the hydraulic tappet valve drive mechanism commonly used in modern gasoline engines, this innovative valve drive mechanism offers the advantage of relatively small friction torque. Reduced camshaft weight: The use of a hot-shrink camshaft not only reduces the weight of the camshaft compared to the original one but also allows the engine to achieve higher cam profile accuracy and more precise valve timing.
I've encountered this issue many times when the engine makes strange noises while turning the steering wheel. It's mostly related to the steering system. The steering system relies on the engine to drive the power steering pump. If the oil in the pump is insufficient or leaking, it's prone to produce squeaking or gurgling sounds. Additionally, if the belt is loose or worn out, it can also create friction noises when under increased load during steering. I recommend first checking the power steering fluid reservoir level to see if it's low. If it's a new sound, take it to a professional mechanic for diagnosis as soon as possible—don't wait until a major problem arises. For regular driving, pay attention to periodic maintenance of steering components and change the fluids more frequently to prevent issues before they occur. Whenever the car makes unusual noises, it can feel unsettling, so addressing them early brings peace of mind.
When turning, the engine makes noise, and I personally think it's usually a minor issue with the power steering system. When the steering wheel is turned, the engine has to work extra to drive the power steering pump. If the belt is worn or loose, it can shake and produce squeaking sounds. Also, insufficient oil pressure or leaks in the lines can make the pump work harder. I experienced this once—my old car always made noise when turning, and replacing the belt fixed it. The issue isn't too complicated, but for safety, don't try to fix it yourself. Have a mechanic check the belt tension with tools. Don't skimp on maintenance—check fluid levels and keep things clean. A healthy power steering system means less noise.
