What Causes the Abnormal Noise When Starting the Magotan?
2 Answers
The abnormal noise when starting the Magotan can be caused by the following situations: Sharp abnormal noise: This is caused by the belt slipping, which is due to insufficient pre-tension of the tensioner or the belt being stretched over time and becoming loose. Gear grinding noise: This is caused by the gear grinding between the starter gear and the engine flywheel gear. The reason is that after prolonged use, the gears of the starter and flywheel wear out severely, resulting in misalignment and grinding sounds. Tapping noise: This sound is produced by the closing of the valves in the engine's valve train. In an engine, the valve train is the noisiest component. This sound is emitted when the intake and exhaust valves close and is generally audible after starting.
I've been driving a Magotan for several years, and sometimes I hear a creaking sound when starting the car, which seems quite common. It's mostly likely an issue with the starter, especially the aging of the starter gear or solenoid valve, which can get stuck during cold starts. Alternatively, it could be due to a loose or slipping engine belt, like the sound produced by friction when the rubber ages. I remember the car didn’t have this problem when it was new—it only started after driving 50,000 to 60,000 kilometers. It’s recommended to check if the belt tensioner is functioning properly. If the sound only occurs during cold starts, it might be due to insufficient or lack of lubrication, causing increased friction between components. Go to a repair shop as soon as possible for a stethoscope or computer diagnosis—don’t delay and risk affecting driving performance. Warming up the car for a minute or two before driving can help alleviate the issue.
