Chirping noise from I think the Serpentine Belt?

I’m a uni student driving across the country and while I was pulling into my hotel, I noticed a chirping sound coming from my hood. I’ve had a small oil leak that I took in to get diagnosed at an auto shop and they said it’s alright as long as I keep track of the oil level and add oil when it’s low. Does anyone know what the problem might be or how serious it is?

Humm, that does not sound like a serpentine belt noise, I would remove the belt and spin the pulleys to see which one is making the noise. Also, while the belt is off, start the engine for a second to see if the noise is gone, it might be internal. Let me know.

It sounds like the chirping could be a belt or pulley issue, especially if it happens when the engine is running. Since you already have an oil leak being monitored, it’s best not to ignore new noises.

Have you tried to remove the belt and start the engine?
