My car just started squeaking under the hood. I have a '94 Le Baron Convertiible, about 49K miles. The sound seems to be coming from one of the belts or pulleys, probably the widest belt or one of the pulleys it’s on. The alternator is on this belt, but it doesn’t seem to be the source of the noise.
Car was OK Friday. Saturday, I was driving in a downpour and hit a puddle, maybe 6 inches deep, that sprayed a lot of water. On Monday morning (yesterday for the calendar impaired), it was squeaking really badly, especially at idle. When accelerating, the squeak would go away. This morning, the squeaks are quieter, but still there.
Any ideas on the probable cause of the squeak, apart from hitting the puddle (water still under the belts? Rust developed on a pulley?)? Is there something I should do, maybe oil the pulleys? Is there a special kind of oil I should use? Or will it just go away on its own over the next few days?
