What Causes the Engine Noise in Buick Excelle?
3 Answers
The causes of engine noise in Buick Excelle are: 1. Excessive oil viscosity; 2. Loose belt; 3. High water temperature; 4. Clogged throttle or fuel injector. Taking the 2021 Buick Excelle as an example, its body dimensions are: length 4609mm, width 1798mm, height 1486mm, with a wheelbase of 2640mm. The 2021 Buick Excelle is equipped with a 1.3L turbocharged engine, delivering a maximum horsepower of 163ps and a maximum power of 120kw, paired with a 6-speed automatic manual transmission. It adopts a front suspension type of MacPherson independent suspension and a rear suspension type of multi-link independent suspension.
Engine noise issues are quite common in the Buick Excelle, which I've personally experienced several times. The main causes are often insufficient or aged engine oil, leading to component friction that produces ticking or rattling sounds. The Buick's chain system is prone to loosening, and chain noise is a clear sign it needs tightening. Additionally, aged belts can produce high-pitched squealing, while excessive carbon buildup may cause knocking sounds at idle, resembling metal collisions. I recommend first checking the oil dipstick yourself and topping up if the level is low. If you hear unusual noises, stop driving immediately instead of forcing it. If the noise persists, promptly visit a professional repair shop to diagnose specific trouble codes with a scanner. Don't underestimate these sounds—they could indicate internal engine damage, and delayed repairs may cost more. Regular maintenance, including oil and belt changes, is key to prevention. While the Buick is user-friendly, engine noises should never be ignored.
Engine abnormal noise is no joke, safety should be taken seriously. For cars like the Buick Excelle, I've observed that such noises often originate from the cooling system or valve issues. For instance, a faulty water pump or fan may produce whooshing or rattling sounds, while incorrect valve clearance can cause ticking noises. If not repaired promptly, it may lead to engine damage and breakdown risks. Upon hearing abnormal sounds, owners should immediately reduce speed and have the vehicle inspected at a 4S shop or reliable garage. For daily prevention, maintaining clean engine oil and performing timely part replacements can effectively reduce the likelihood of abnormal noises. Every driver knows that noise often hides potential hazards – only by fixing it can one travel with peace of mind.
