Reasons for Engine Abnormal Noise After Vehicle Wading
1 Answers
After a vehicle wades through water, the most common cause of engine abnormal noise is insufficient lubrication of vehicle bearings due to water exposure. Other reasons for abnormal noise are as follows: 1. Foreign objects: If abnormal noise occurs during braking immediately after wading, it is caused by moisture or impurities in the brake discs. The noise will disappear once the water is worn off, provided no foreign objects are present. 2. Water entering the transmission: If abnormal noise occurs in the transmission during idling or driving after wading for some time, it is due to insufficient lubrication of internal bearings caused by water entering the transmission. 3. Moisture entering internal bearings: If abnormal noise occurs in the front part of the engine during idling or driving after wading for some time, it is caused by insufficient lubrication due to moisture entering the internal bearings of components like the generator belt tensioner or generator.
