What is the reason for the loud whining sound when accelerating in the Sagitar?
3 Answers
The possible causes of loud abnormal noise when accelerating in the Sagitar include: insufficient engine oil in the engine; long-term failure to change the engine oil affecting performance; excessively low viscosity of the engine oil. During operation, the engine oil forms a thin film on the surfaces of various components inside the engine, which reduces friction and helps dissipate heat. Precautions for using a car engine are as follows: 1. Avoid driving in neutral: The engine itself has a fuel cut-off function during deceleration, and driving in neutral is not conducive to fuel economy; 2. Pay attention to observation during daily use: If oil is found on the ground, determine whether there is an engine oil leak and promptly communicate with the car 4S store to eliminate safety hazards; 3. For cars equipped with turbochargers: Do not turn off the engine immediately after high-speed driving or climbing a slope. Let it idle for 10 minutes before turning it off. Cars with turbochargers accumulate carbon deposits several times faster than naturally aspirated cars; 4. When brake fluid is contaminated with or absorbs water, or if impurities or sediment are found in the brake fluid, it should be replaced or carefully filtered in time. Otherwise, it may lead to insufficient braking pressure, affecting braking performance.
I've been driving my Sagitar for nearly ten years, mainly for daily commuting, and have encountered the whining noise when accelerating several times. Most often, it's due to the engine belt being too loose or worn out. A loose belt can cause friction and produce that sound, which disappears after replacing it with a new one. A clogged air filter is another common cause; restricted airflow can lead to a whining noise, so regular cleaning or replacement can prevent this. For turbocharged models, failed seals might also be the culprit. I always advise car owners to get it checked early to avoid long-term engine damage. Safety comes first—if the noise grows louder and affects concentration, visit a repair shop promptly to prevent breakdowns and unnecessary delays.
As the primary driver in the family, I encountered a whining noise when accelerating while driving my Sagitar to take the kids to school, mainly due to belt issues or intake system blockage. Over time, belts wear out and harden, causing annoying buzzing sounds; a dirty air filter restricting airflow can also produce similar noises, which can be improved by replacing it with a clean one. Last time I had a mechanic check it, I realized small issues can accumulate into major problems if neglected. It's important to pay attention to regular maintenance cycles, such as inspecting the belt every six months, to keep the engine running quietly and ensure more worry-free and comfortable long-distance drives.
