What causes the abnormal noise in the new Santana three seconds after ignition?

New Santana engine abnormal noise after ignition is caused by belt slippage. Below is an introduction to engine belt slippage and abnormal noise: Causes of engine belt slippage: It is usually due to damaged bearings in the generator, water pump, or power steering pump; if it is a sound of air leakage during engine operation, it may be caused by a blocked exhaust system, vacuum tube leakage, or breakage. Engine abnormal noise indicates that the technical state of a certain engine mechanism has changed, mainly caused by excessive wear of some parts or improper assembly and adjustment. Solutions for engine abnormal noise: Issues caused by engine oil require timely replacement; problems with the timing system need replacement; loose or aged engine mounts require repair and replacement; issues caused by the throttle need cleaning. Abnormal noises in motor vehicles must not be ignored, as they can pose safety risks to vehicle usage.
This is a common issue I encounter when repairing cars. The new Santana makes abnormal noises three seconds after starting, most likely due to problems with the pulley or fan. The engine compartment of the new Santana is compactly designed, and the temperature changes rapidly after starting. The belt might be loose or worn, causing friction noise when the fan kicks in after three seconds. Additionally, the assembly of new cars can sometimes be less tight, and plastic parts expanding and contracting with heat can also produce squeaking sounds. I recommend opening the hood to identify the source of the noise. If it's coming from the belt or fan area, take it to a repair shop promptly to adjust the tension. New cars often have such minor issues during the break-in period. While not major problems, it's best to fix them early to avoid belt breakage, which could affect driving safety.
I've been driving for several years, and my new Santana makes strange noises after starting, most likely due to the air conditioning compressor. The system automatically activates the compressor three seconds after starting the engine. If the fan bearings are worn or the motor has issues, it will produce a buzzing sound. My old car had a similar problem before, and replacing the fan solved it. Although the car is new, the quality of parts may not be stable, and the increased load after starting can cause noise. Don't ignore this small sign. First, try turning off the AC before starting the engine to see if the noise persists. If it disappears, it indicates an issue with the compressor or fan, and the parts should be replaced.
