How to Perfectly Solve the Clicking Sound in Verano?

One effective method is to add an anti-wear additive. Below is a detailed introduction on how to resolve the clicking sound in Verano: 1. Function of Anti-wear Additive: This additive can be added to the engine without affecting its operation. If the sound disappears, it indicates excessive friction gaps between internal components. Large gaps can cause knocking sounds. In such cases, components like push rods, lifters, and piston rings may need replacement. However, to accurately identify the issue, disassembling the cylinder and replacing parts is necessary—there are no other alternatives. 2. Cause: Generally, during cold starts, most cars experience slightly louder engine sounds compared to when the engine is warm. As long as the sound is uniform, smooth, and not harsh, it usually isn't a problem. This occurs because, when cold, the gap between the cylinder wall and piston hasn't reached the optimal size, and the lubrication from the engine oil isn't fully effective. Typically, when the engine block temperature reaches around 95 degrees, the sound will return to normal.
I've dealt with many cases of the ticking sound in the Verano. Common causes include excessive engine valve clearance or loose timing chain. First, identify the source: if it occurs during cold starts and disappears when the engine warms up, it's likely the chain; if it persists at idle, it may be a valve issue. You can check the oil level and quality yourself - low or poor-quality oil can worsen the noise. Use a stethoscope to locate the sound source at the top or side of the engine, but don't tamper with components. I recommend visiting a 4S shop to have technicians measure the clearance or check the chain tensioner - a simple adjustment can fix it at low cost. For daily maintenance, choose good quality oil and change it regularly to prevent ticking sounds.
When driving my Verano, I encountered a ticking sound that seemed like something knocking inside the engine. After researching, I found it could be due to a loose connecting rod small end or a failed water pump bearing. I tried checking if the belt was worn out—a loose belt can produce similar noises, so tightening or replacing it might help. If the sound is accompanied by vibration, it's also worth checking if the engine mounts are worn. My advice is not to delay—visit a professional repair shop as soon as possible. They can diagnose it more accurately with specialized tools. After spending some money on repairs, the noise disappeared, and I felt much more at ease while driving. Usually, I pay attention not to stomp on the accelerator too hard; gentle driving helps reduce wear and tear.
