How to Solve the Squeaking Noise from Wet Car Belts?

[VioletDella]

When driving through waterlogged roads, the splashing water causes the engine belt to slip after getting wet, resulting in abnormal noise from the engine belt. If the engine belt continues to make noise after drying, it indicates that the belt is too loose and needs to be replaced with a new one.

I've been working as a mechanic in the auto shop for many years and have seen countless cases of belts squealing after getting wet. The main reason is water getting between the belt and pulleys, reducing friction and causing slippage, which produces that annoying screeching sound. For a quick fix, you can try using a hairdryer to dry the belt area or simply spray some specialized belt anti-slip agent. But in the long run, leaving this issue unresolved can be dangerous—old belts might stretch and crack, and pulleys could rust. My advice is to not rush driving after going through water. Stop the engine and check the belt tension. If it's loose, adjust the tensioning bolt immediately. If that doesn't work, take it to a professional shop and have a technician measure it with a tension gauge. Safety always comes first—don't let that little noise turn into an engine overhaul.
