Why does the Mercedes-Benz B200 make a humming noise when running?
1 Answers
The abnormal noise from the Mercedes-Benz B200 while running is related to issues with engine oil, belts, and water temperature. Engine oil aspect: If the engine oil viscosity is too high, it can cause problems with engine operation, reduce lubrication effectiveness, and result in louder engine noise. It is essential to promptly visit a repair shop to check if the engine oil needs replacement. Belt aspect: Check if the belt is loose. A loose belt can lead to increased noise in the engine compartment. Water temperature aspect: Overheating can also cause abnormal engine noise. Check if the temperature gauge is normal and if there is any smoke coming from the engine compartment. Remember to replace the coolant before winter.
