Why Does the Car Make Squeaking Noises When Driving in the Rain?

This is caused by the contact surface between the belt and the pulley becoming too smooth. It usually occurs when the engine speed changes rapidly, and sometimes increased load on the belt-driven accessories can also cause belt damage. Here are the relevant details: 1. Solution: Check if the belt-driven accessories have damaged bearings, are stuck, loose, or if the accessory power has increased. Replace the belt, or use 100-grit sandpaper to roughen the contact surface between the pulley and the belt. As a temporary fix, you can apply 1-2 drops of engine oil to the contact surface between the belt and the pulley. 2. Precautions for driving in the rain: Before driving in the rain, carefully check if the wipers are functioning effectively to ensure they work flawlessly when needed. During rain, the sky is often dark, and rainwater on the windshield can severely obstruct visibility. Turn on the wipers to promptly clear rainwater from the windshield, maintain good visibility, and turn on the headlights, fog lights, and taillights based on visibility conditions.
